The extragalactic γ-ray background: imprints from the physical properties and evolution of star-forming galaxy populations

ABSTRACT Star-forming galaxies (SFGs) harbour an abundant reservoir of cosmic rays (CRs). At GeV energies, these CRs undergo interactions with their environment to produce γ-rays, and the unresolved γ-ray emission from populations of SFGs form a component of the isotropic extragalactic γ-ray background (EGB). In this work, we investigate the contribution to the 0.01–50 GeV EGB from SFG populations located up to redshift z = 3. We find this is dominated by starbursts, while the contribution from main-sequence SFGs is marginal at all energies. We also demonstrate that most of the γ-ray contribution from SFGs emanates from low-mass galaxies, with over 80 per cent of the emission originating from galaxies with stellar masses below $10^8 \, {\rm M}_{\odot }$. Many of these galaxies are located at relatively high redshift, with their peak EGB contribution arising ∼700 Myr before the noon of cosmic star formation. We find that the precise redshift distributions of EGB sources at different energies imprint intensity signatures at different angular scales, which may allow their contribution to be distinguished using analyses of small-scale EGB intensity anisotropies, particularly if the diffuse EGB is dominated by hadronic CR-driven γ-ray emission from SFGs. We show that the EGB is sensitive to the evolution of low-mass populations of galaxies, particularly around z ∼ 2.5, and that it provides a new means to probe the engagement of CRs in these galaxies before the high noon of cosmic star formation.

High Noon Reclamation, and: Untitled 2 Ate Untitled 1 Tania Chen (bio) High Noon Reclamation Your loneliness is a long-term project. You sit with it, stones in your mouth; edge to edge, front to back, the light on the wall creeps. You replace the stones with musical notes and your family memory resides in a distant country (—the memory waking old aches that belong to your great-grandfather and the war wounds he brought with him across the sea). Your great-grandmother kept washing old clothes until they were all brightly bleached (—you don't remember her face, just her hands: calloused and worked to the bone). Your grandparents, your parents, they were just tests, a way of setting the ground (—but you, you are different. Meant to be so much better, meant to fit in under the bright noon sun). There is no place to hide the inadequacy of your being, too much and too little by any rule you're measured with. Your parents have given too much to fit in (—they hope, as their parents did before, that you are shaped correctly enough to make this). Your mouth knows how to pronounce all the words your grandmother stumbled on. The words your great-grandmother never bothered to learn (—in return you've given up the voice of your ancestors — the language feels awkward in you).

Evaluation on the fresh eating quality of tree peony flowers

Tree peony (Paeonia suffruticosa) is an ornamental and medicinal plant in China. The fresh eating of flower petals has gradually become a new idea for further development. This study analyzed the sensory indexes, nutritional indexes and antioxidant indexes of fresh flowers of five cultivars, namely, ‘Fengdan’ (P. ostia ‘Fengdan’), ‘Xiangyu’ (P. suffruticosa ‘Xiangyu’), ‘Zhaofen’ (P. suffruticosa ‘Zhanfen’), ‘Luoyanghong’ (P. suffruticosa ‘Luoyanghong’) and ‘High Noon’ (P. ‘High Noon’), to provide a theoretical basis for eating fresh tree peony flowers. The aroma volatiles of petals mainly comprised terpenes, alcohols and alkanes. ‘Luoyanghong’ and ‘High Noon’ have brighter colors. The taste test showed that ‘Luoyanghong’, ‘High Noon’ and ‘Xiangyu’ were the most palatable. ‘High Noon’ contained the highest soluble sugar content, ‘Luoyanghong’ contained the highest starch and vitamin C (VC) levels, and ‘Zhaofen’ contained the highest soluble protein content. The contents of bioactive compounds were the highest in ‘Luoyanghong’, and superoxide dismutase (SOD) activity was the highest in ‘Xiangyu’. The petals were rich in essential amino acids, with the highest amount in ‘Xiangyu’. ‘Luoyanghong’ and ‘High Noon’ showed strong antioxidant capacity. Therefore, tree peony flowers have excellent sensory qualities, abundant nutrients and strong antioxidant activity and could be further developed as a food to be eaten fresh. The results showed that tree peony flowers had great edible potential. Flowers of red and yellow cultivars can be considered for fresh eating on the basis of the traditional consumption of white and pink tree peony flowers.

CLEAR: Emission-line Ratios at Cosmic High Noon

Abstract We use Hubble Space Telescope Wide Field Camera 3 G102 and G141 grism spectroscopy to measure rest-frame optical emission-line ratios of 533 galaxies at z ∼ 1.5 in the CANDELS Lyα Emission at Reionization survey. We compare [O iii]/Hβ versus [S ii]/(Hα + [N ii]) as an “unVO87” diagram for 461 galaxies and [O iii]/Hβ versus [Ne iii]/[O ii] as an “OHNO” diagram for 91 galaxies. The unVO87 diagram does not effectively separate active galactic nuclei (AGN) and [Ne v] sources from star-forming galaxies, indicating that the unVO87 properties of star-forming galaxies evolve with redshift and overlap with AGN emission-line signatures at z > 1. The OHNO diagram does effectively separate X-ray AGN and [Ne v]-emitting galaxies from the rest of the population. We find that the [O iii]/Hβ line ratios are significantly anticorrelated with stellar mass and significantly correlated with log ( L H β ) , while [S ii]/(Hα + [N ii]) is significantly anticorrelated with log ( L H β ) . Comparison with MAPPINGS V photoionization models indicates that these trends are consistent with lower metallicity and higher ionization in low-mass and high-star formation rate (SFR) galaxies. We do not find evidence for redshift evolution of the emission-line ratios outside of the correlations with mass and SFR. Our results suggest that the OHNO diagram of [O iii]/Hβ versus [Ne iii]/[O ii] will be a useful indicator of AGN content and gas conditions in very high-redshift galaxies to be observed by the James Webb Space Telescope.

Genome-Wide Identification and Comparative Profiling of MicroRNAs Reveal Flavonoid Biosynthesis in Two Contrasting Flower Color Cultivars of Tree Peony.

MicroRNA (miRNA)-mediated gene regulation is involved in various physiological processes in plants. Flower color is one of the vital ornamental traits of tree peony (Paeonia suffruticosa Andr.). However, the yellow-flowered tree peony cultivars are particularly rare. To elucidate the miRNA-mediated gene regulatory mechanism underlying yellow pigmentation in tree peony, we combined pigment assessment, miRNA identification, expression analysis, and gene functional verification in two contrasting flower color cultivars “High Noon” and “Roufurong.” Flavones/flavonols and anthocyanins were found to be the main contributors to the coloration of “High Noon” and “Roufurong” petals, respectively. Subsequently, miRNA analysis based on available genome data identified 9 differentially expressed miRNAs and 12 relevant target genes implicated in flavonoid biosynthesis. Their dynamic expression patterns determined the key role of mdm-miR156b-PsSPL2 module in yellow pigmentation of tree peony flowers. The sequence analysis and subcellular localization validated that PsSPL2 might function as a nuclear-localized transcription factor. Overexpression of PsSPL2 in tobacco resulted in a decrease of anthocyanin content and down-regulation of NtF3′H and NtDFR transcripts. PsSPL2-silenced petals exhibited lighter yellow color, and the contents of THC, Ap, and Ch decreased significantly. Meanwhile, expression levels of PsCHS, PsCHI, and PsF3H were significantly decreased in the petals with PsSPL2 silencing, while those of PsF3′H and PsDFR were remarkably increased. This study offers a novel insight into yellow pigmentation-related miRNA regulation network in tree peony, and further provides the valuable information on physiological changes during yellow coloring process of tree peony.

John Wick: Keanu Reeves’s Epic Adventure

Three films create the John Wick universe and franchise: John Wick (2014), John Wick: Chapter 2 (2017), and John Wick: Chapter 3, Parabellum (2019). A fourth film is scheduled to be released in March 2023. All are wildly popular, and all are criticized for violence, particularly gun violence. I argue, however, that by examining the visual references that appear in all the films, it becomes clear that the films are defending themselves from such attacks through their allusions to ancient and classical epics from around the world. As Wick battles his way through museums and beautiful cities, the film reminds us that art, all art—fine and popular--relies on violence. Wick follows many of the traditions of the epic hero, and in the end, thanks to the visual cues in the films, he is no different than Achilles or Hector or even High Noon’s Will Kane. And if there is a hero, and if there is art, there will be blood.

Tiny Towns

Tiny Towns Michael Dowdy (bio) The roads end At motels. —Weldon Kees, "Travels in North America" Inns are not residences. —Marianne Moore, "Silence" 1 Some folks say a family business "gets in the blood." But they're usually mum on how many generations it requires, or how many decades it takes for the blood to drain, drop by drop, as the puddle beneath your sneakers congeals into a clot of unconfirmed stories. My [End Page 96] grandfather is a dozen years dead, my grandmother's a summer gone, my father's over seventy. Poking around their family business, I'm finding that folks also fail to add that toxins "get in the blood," too. ________ My family's business began with a restaurant that's eroding from my kin's memory. All that remains is a name: Tiny Town. This crack in our origin story may've been caused by a shift in our foundation, its crawl spaces now dank and impassable. For JB, my grandfather, like my father, wasn't a restaurant man. He was a motel man. The restaurants he left in a trail of ashes. ________ JB opened Tiny Town Restaurant in Pearisburg, near the rugged border between southwest Virginia and southern West Virginia, in 1954. Pearisburg was fifteen minutes from the shack where he was born, where three of his siblings had died, near where JB's schoolhouse burned down when he was seven, ending his formal education. I don't know why JB named the joint Tiny Town, whether it was his fondness for alliteration or a short-lived matter-of-factness. Given the man I knew and loved, it wasn't humility or any of its cousins. ________ Tiny Town opened when my father was five. That year he and my two uncles climbed on top of their Ripplemead trailer and threw flaming trash into my grandfather's pickup, which burned to a crisp. The temptation of fire, I'd later learn, was rumored to run in the family. Pearisburg is indeed a tiny town, [End Page 97] but it's mammoth compared to where he grew up, between the pinpricks of Pembroke and Hoge's Chapel. The New River flows past all three dots. Unlike his aptly named restaurant, the New is a misnomer—the world's second oldest river cuts through one of the world's oldest mountain ranges. Near its banks, tiny towns like Ripplemead abound. ________ Another Tiny Town appears in season three of the Netflix cult classic Arrested Development. As the Bluth family, their family business, and the show itself unravel before our eyes, the Bluths build on the hillside behind their own model home a model-sized village of model homes. The Bluth's Tiny Town is a bait-and-switch designed to fool their Japanese investors, who will, the racist Bluths believe, stare in awe through binoculars and miss the tricks of perspective and scale. Yet it's the Bluths, not their investors, who mistake the appeal of their scheme. In their arrogance and desperation, the gigantic—their incompetence, xenophobia, and self-sabotage—shrinks. In real life, the small can appear outsized, especially up close or at high noon. Getting a durable sense of the scale and perspective of one's inheritance requires a tricky mix of curiosity and forbearance that the Bluths sorely lack. ________ My family's family business wasn't run by Bluthian sociopaths, and our Blue Ridge hustles were a far cry from the Bluths' Hollywood schemes. But, like theirs, ours was agonistic, dysfunctional, ever edging toward dissolution. My grandfather's Tiny Town, like many of his businesses, lasted only a few years. Like the Bluths, whose real estate acumen [End Page 98] consisted of hunches and gambles, JB led with his gut. Like the Bluth patriarch George, whose Banana Stand went up in flames, JB had a business or two burn to the ground. One rumor ran that he torched them for insurance cash. I've found little evidence of that, other than ashes, and ashes rarely speak. Were his fires the result of going-it-alone? Now, cable TV brands such instincts as DIY. Then, it was simply the ingrained habit...

A Physical Model for the Quasar Luminosity Function Evolution between Cosmic Dawn and High Noon

Abstract Modeling the evolution of the number density distribution of quasars through the quasar luminosity function (QLF) is critical to improving our understanding of the connection between black holes, galaxies, and their halos. Here we present a novel semiempirical model for the evolution of the QLF that is fully defined after the specification of a free parameter, the internal duty cycle, ε DC, along with minimal other assumptions. All remaining model parameters are fixed upon calibration against the QLF at two redshifts, z = 4 and z = 5. Our modeling shows that the evolution at the bright end results from the stochasticity in the median quasar luminosity versus halo mass relation, while the faint end shape is determined by the evolution of the halo mass function (HMF) with redshift. Additionally, our model suggests the overall quasar density is determined by the evolution of the HMF, irrespective of the value of ε DC. The z ≥ 4 QLFs from our model are in excellent agreement with current observations for all ε DC, with model predictions suggesting that observations at z ≳ 7.5 are needed to discriminate between different ε DC. We further extend the model at z ≤ 4, successfully describing the QLF between 1 ≤ z ≤ 4, albeit with additional assumptions on Σ and ε DC. We use the existing measurements of quasar duty cycle from clustering to constrain ε DC, finding ε DC ∼ 0.01 or ε DC ≳ 0.1 dependent on observational data sets used for reference. Finally, we present forecasts for future wide-area surveys with promising expectations for the Nancy Grace Roman Telescope to discover N ≳ 10, bright, m UV < 26.5 quasars at z ∼ 8.

Revisiting the Blacklist Western: A Reception Study of High Noon

This article deploys primary archival research into local newspaper articles, to assess the extent to which High Noon (Fred Zinnemann, 1952) was received as a film with a contemporary political message pertaining to the Hollywood blacklist on its initial cinematic release. Various pre-existing assumptions surrounding the film’s entry into the public sphere are interrogated: by revealing that the film was overwhelmingly hailed as an instant genre classic; by examining the levels of awareness around writer Carl Foreman’s role; and by analysing concordances between news coverage of the House Un-American Activities Committee and that of High Noon. The article thereby seeks to illuminate the fragmentary nature of political discourse in Cold War-era popular culture.

Hope for Labor at the End of History

Williams, Joshua Freeman, and John Sweeney. (Courtesy of Columbia University Archives) [End Page 110] It was “the end of history”: America in the 1990s. Francis Fukuyama published a book with that title in 1992. Things would continue to happen, according to the philosopher, but the underlying story line had come to a finish with the triumph of liberal democracy and capitalism. As the decade wore on, Fukuyama’s prophecy seemed practically clairvoyant. At the turn of the millennium, Bob Dylan captured the zeitgeist: “I used to care, but things have changed.” Yet how could that be? Talk of a second Gilded Age of gross disparities in income and wealth was already commonplace. Homelessness, declining wages, a reemergence of sweatshop labor, an explosion of a contingent and deeply insecure labor force, a population of the working poor numbering in the tens of millions, industrial ghost towns, the surgical removal of a whole occupational species of middle managers—on and on went the litany of what the “market republic” had accomplished. CEO pay had grown to 500 times that of the average worker. This was the high noon of bipartisan neoliberalism in the United States. Bill Clinton was the new president, and by the time he had finished taking his inaugural oath he had jettisoned the faintly populist aroma of his campaign. After failing to extend healthcare to millions of uninsured, Clinton responded to a Republican triumph in the 1994 midterm elections with punitive workfare reform, ending, as he said, “welfare as we know it.” Talk of labor-law reform was silenced. Republicans and Democrats found common ground when it came to shrinking the welfare state, and the Democrats took the lead in accelerating mass incarceration through a crime bill in 1994. A systematic deregulation of Wall Street would come later during Clinton’s watch. All of this was good for business. A galaxy of business-oriented foundations, think tanks, magazines, policy ateliers, television and radio commentators, newspaper editorialists, and megachurches applauded the new wisdom, formed its programs, lobbied for its interests, lent it intellectual ballast, and rationalized its social unconsciousness. [End Page 111] Nothing resembling a social opposition of any muscle was in sight. Organized labor was nearly comatose. It had once represented a third of the labor force; now that was down to a sixth, and only 10 percent in the private sector. When strikes happened, which was less and less frequently, they usually ended in failure or, at best, preserved the status quo. The last great social movements to disturb the equanimity of American life—the civil rights movement especially, but also the antiwar and feminist insurrections—had taken place decades earlier and were receding rapidly from view. Trace amounts of that unruly era were detectable here and there. But, for all practical purposes, the labor movement was dead, the Black liberation movement was dead, the anti-imperial movement was dead, the feminist movement was dead. News from Nowhere Then, on a crisp October evening in 1996, something totally unexpected happened. Somewhere in the neighborhood of 2,000 people showed up at Columbia University to attend an event called “The Fight for America’s Future: A Teach-In with the Labor Movement.” People came from up and down the East Coast. Busloads of students arrived from area colleges. Professors mixed with transit workers and schoolteachers. The young, the old, and the middle-aged rubbed shoulders. There were about 1,500 more attendees than the organizers of the event anticipated. The rotunda of Low Library, where the opening plenary of the two-day teach-in was to convene, was packed; fire marshals ordered it closed to further entrants. Improvising, organizers set up loudspeakers outside, and two auditoriums were commandeered, one with an audio feed and the other with a closed-circuit television, to accommodate at least some of the overflow.

High noon for the Union?

Next May, the SNP will be defending a fourteen year record in office in Edinburgh. Typically, governments find it difficult to secure electoral success in such circumstances. The 'costs of government' – the almost inevitable gap between a party's initial promises and voters' perceptions of what has actually been achieved – usually take their toll at the ballot box (Green and Jennings, 2017). Yet, even though the SNP administration has had its fair share of difficulties and disappointments during its now lengthy time in office, just how well it has met the challenges of the last 14 years may come to matter little in voters' minds when they decide how to cast their ballot.

BIRTH of the COSMOS field: primordial and evolved density reconstructions during cosmic high noon

ABSTRACT This work presents the first comprehensive study of structure formation at the peak epoch of cosmic star formation over 1.4 ≤ z ≤ 3.6 in the Cosmic Evolution Survey (COSMOS) field, including the most massive high-redshift galaxy proto-clusters at that era. We apply the extended COSMIC BIRTH algorithm to account for a multitracer and multisurvey Bayesian analysis at Lagrangian initial cosmic times. Combining the data of five different spectroscopic redshift surveys (zCOSMOS-deep, VUDS, MOSDEF, ZFIRE, and FMOS–COSMOS), we show that the corresponding unbiased primordial density fields can be inferred, if a proper survey completeness computation from the parent photometric catalogues, and a precise treatment of the non-linear and non-local evolution on the light-cone is taken into account, including (i) gravitational matter displacements, (ii) peculiar velocities, and (iii) galaxy bias. The reconstructions reveal a holistic view on the known proto-clusters in the COSMOS field and the growth of the cosmic web towards lower redshifts. The inferred distant dark matter density fields concurrently with other probes like tomographic reconstructions of the intergalactic medium will explore the interplay of gas and dark matter and are ideally suited to study structure formation at high redshifts in the light of upcoming deep surveys.

Elia Kazan and the Hollywood Blacklist

In April 1952, Elia Kazan appeared before HUAC and named names. Although he refused to do so in an earlier appearance, this time, having been warned that his film career was in jeopardy, he named many of his colleagues and friends. While he is far from the only one to turn informer, his case garners the most attention for a variety of reasons. In this essay, I examine Kazan’s justifications for his acts, acts that contributed to the destruction of the careers of many of his talented colleagues and friends. I wish to discover whether his arguments are philosophically plausible and how the themes in his film On the Waterfront (1954) contribute to the debate over these issues. In contrast, I examine the film High Noon (1952), largely seen as an attack on the practice of informing. I examine how Utilitarian and Kantian moral theories might be used either to justify or condemn Kazan’s actions. Finally, if we stipulate that Kazan’s acts before HUAC were immoral, does this mean that we should boycott his art or deny him accolades that his work would otherwise merit?

High-NOON States with High Flux of Photons Using Coherent Beam Stimulated Noncollinear Parametric Down Conversion

We show how to reach high fidelity NOON states with a high count rate inside optical interferometers. Previously, it has been shown that by mixing squeezed and coherent light at a beam splitter, it is possible to generate NOON states of arbitrary N with a fidelity as high as 94%. The scheme is based on higher-order interference between “quantum” down-converted light and “classical” coherent light. However, this requires optimizing the amplitude ratio of classical to quantum light, thereby limiting the overall count rate for the interferometric super-resolution signal. We propose using coherent beam stimulated noncollinear two-mode down-converted light as input to the interferometer. Our scheme is based on the stimulation of noncollinear parametric down conversion by coherent light sources. We get a better flexibility of choosing the amplitude ratio in generating NOON states. This enables super-resolution intensity exceeding the previous scheme by many orders of magnitude. Therefore, we hope to improve the magnitude of N-fold super-resolution in quantum interferometry for arbitrary N using bright light sources. We give improved results for N = 4 and 5.
