Deep Lyman alpha imaging of radio galaxy 1138-262 at redshift 2.2
J. D. Kurk, H. J. A. Roettgering, L. Pentericci +1
Observations of the powerful radio galaxy 1138-262 at z=2.2 suggest that this galaxy is a massive galaxy in the center of a forming cluster. We have imaged the field of 1138-262 wi…
Jet-Induced Emission-Line Nebulosity and Star Formation in the High-Redshift Radio Galaxy 4C41.17
Geoffrey V. Bicknell, Ralph S. Sutherland, Wil J. M. van Breugel +3
The high redshift radio galaxy 4C41.17 consists of a powerful radio source in which previous work has shown that there is strong evidence for jet-induced star formation along the r…
A Radio Galaxy at z=5.19
Wil van Breugel, Carlos De Breuck, S. A. Stanford +3
We report the discovery of the most distant known AGN, the radio galaxy TN J0924-2201 at z = 5.19. The radio source was selected from a new sample of ultra-steep spectrum (USS) sou…
HST Snapshot Survey of 3CR Quasars: The Data
Matthew D. Lehnert, George K. Miley, William B. Sparks +6
We present images taken with the Wide Field Planetary Camera (WFPC-2) on the Hubble Space Telescope of 43 quasars selected from the 3CR radio catalog. The redshift range of the tar…
Optical spectroscopy of faint gigahertz peaked spectrum sources
I. A. G. Snellen, R. T. Schilizzi, M. N. Bremer +3
We present spectroscopic observations of a sample of faint Gigahertz Peaked Spectrum (GPS) radio sources drawn from the Westerbork Northern Sky Survey (WENSS). Redshifts have been…
