"The most Distant Radio Galaxies"

ABSTRACT:"During the last decade the number of known radio galaxies with measured redshifts well over 2 has grown dramatically. There are now more than 150 radio galaxies with $z> 2$ and these galaxies are important laboratories for studying the early Universe, because they generally emit three components (IR-optical-UV continuum, emission lines and radio continuum) that are all highly luminous. "During the talk recent observational results will be discussed including: (i) UV/optical morphologies as seen by HST, (ii) the dynamics of the absorbing and line emitting gas as observed with the NTT and (iii) the nature of the dust as probed by SCUBA. The results will be discussed in the context of models of galaxy formation."
