Abstract

A wide variety of recent observations related to active galaxies at large redshifts is reviewed. Studies of galaxies with the Hubble Space Telescope have shown that active star formation in galaxies has continued over the same redshift interval over which active galaxies display strong cosmological evolution. At redshifts greater than 2, there is evidence that many galaxies underwent bursts of continued star formation and that, at the largest redshifts, z ∼ 3, the comoving space density of star-forming galaxies is approximately half of that of luminous galaxies (L ≥ L*) at the present day. Radio galaxies at redshifts z ∼ 1 have high optical surface brightness emission regions stimulated by the passage of the radio jets responsible for powering their large-scale radio structures. The significance of these results for understanding the cosmological evolution of active galaxies is discussed.
