It is now possible to observe the era of the first stars. Lyman-alpha emitter (LAE) surveys have been able to locate galaxies at high redshifts (5Another observational signature of the first stars may be found in the Near Infrared Background (NIRB), which could partially be the redshifted UV photons from stars responsible for reionization. Using analytical models, the light from various populations of stars (with different mass spectra and metallicities) were modeled. The overall intensity of the NIRB can give the star formation rate at high redshifts (7E.R.F. acknowledges support from a Continuing Fellowship of the University of Texas at Austin.
