Abstract
The Astrophysical Multimessenger Observatory Network (AMON) was founded to tie the world’s high-energy and multimessenger observatories into a single network, with the purpose to enable the discovering of multimessenger sources, to exploit these sources for purposes of astrophysics, fundamental physics, and cosmology, and to explore archival datasets for evidence of multimessenger source populations. Contributions of AMON to date include the GCN prompt alerts for likely-cosmic neutrinos, multiple follow-up campaigns for likely-cosmic neutrinos including the IceCube-170922A event, and several archival searches for transient and flaring γ + ν and ν + CR multimessenger sources. Given the new dawn of multimessenger astronomy recently realized with the detection of the neutron binary star merger and the possible γ + ν coincidence detection from the blazar TXS0506+056, in 2019, we are planning to commission several multimessenger alert streams, including GW + γ and high-energy γ + ν coincidence alerts. We will briefly summarize the current status of AMON and review our monitoring plans for high-energy and multimessenger AMON alerts during what promises to be a very exciting year for multimessenger astrophysics.
Highlights
Multimessenger astrophysics centers on the understanding of astrophysical phenomena by looking at the properties of the different messengers of the forces of nature
In 2017, the first detection of EM radiation and gravitational waves (GWs) was made when a binary neutron star merger was observed. This event was first observed by the LIGO observatory, together with the INTEGRAL and the Fermi Gamma-ray Burst Monitoring telescopes
Astrophysical Multimessenger Observatory Network (AMON) is a network that was conceived with the main purpose of enabling coincidence analysis between different detectors and observatories to study astrophysical multimessenger sources
Summary
Multimessenger astrophysics centers on the understanding of astrophysical phenomena by looking at the properties of the different messengers of the forces of nature. These messengers are electromagnetic (EM) radiation, cosmic rays (CR1 ), neutrinos and gravitational waves (GWs). In 2017, the first detection of EM radiation and GWs was made when a binary neutron star merger was observed. This event was first observed by the LIGO observatory, together with the INTEGRAL and the Fermi Gamma-ray Burst Monitoring telescopes. The acronym will refer to ultra-high energy cosmic rays, since the data is obtained from the Pierre Auger Observatory
