Scientific paper
Following a successful HST pilot project, we propose to study the continuum and Ly Alpha morphologies for a sample of 20 z > 2 radio galaxies. During the pilot project ultraviolet continua were detected from two of the most distant galaxies known, 4C 41.17 at z = 3.8 and 4C 28.58 at z = 2.9. The HST morphologies show multiple small-scale (~ 0.1") clumps which in 4C 41.17 are closely associated with the radio source. These results (i) constrain the nature of distant radio galaxies, (ii) imply that spatial scales in distant radio galaxies are well suited for mapping with the HST and (iii) provide compelling arguments for enlarging the sample., Our 20 new targets have been chosen from 50 candidates to be bright in both continuum and Ly Alpha. We would image all 20 in the continuum and 5 of them in Ly Alpha through the appropriate linear ramp filters. The observations would elucidate sub- kiloparsec-scale structures in the target galaxies, allowing study of their alignment and relationships to the associated radio sources. Of particular interest is a comparison between the HST clumpiness and the recently discovered spatially- extended absorption systems in the Ly Alpha profiles. The project would provide unique information relevant to the formation and evolution of radio galaxies, to relationships between galaxy and quasar activity and to physical conditions in the early Universe.
