Calculations Mannucci, Filippo ; Beckwith, Steven V. W. Abstract The first generation of stars at high redshift should have produced bright optical lines of common elements. These lines would appear now in near-infrared bands. We estimate the line fluxes and large-area surface brightnesses of the prominent lines Lyα, Hα, Hβ, [O III] λ5007, and [O II] λ3727 from the first galaxies under a variety of assumptions about the epochs of star formation and cosmology. The results show that these galaxies are within the reach of the present generation of infrared instrumentation for a wide range of star formation histories. We discuss the efficacy of searching for emission-line objects in the near-infrared as a means of finding primeval galaxies and discuss the possible searching strategies with respect to the expected intrinsic scatter of the properties of the forming galaxies.
