Lyman-alpha galaxies at large redshifts.
Abstract
Strong Lyα emission has been detected from several different types of distant galaxies, radio galaxies and their companions at z ≅ 1.8, and galaxy companions of quasars at z > 3. This line emission is a good way of detecting galaxies at very large redshifts, and a powerful probe of the physical conditions and processes in them. A subset of the Lyα radio galaxies have photometric, spectroscopic, and morphological properties unlike those of any previously known class of objects, and may be interpreted as galaxies in the process of formation.
