Triggered Star Formation in a Massive Galaxy at z=3.8: 4C41.17 (1997)

Dey, Arjun, Van Breugel, Wil, Vacca, William, Antonucci, Robert

Spectropolarimetric observations obtained with the W. M. Keck Telescope of the z=3.8 radio galaxy 4C41.17 show that the UV continuum emission from this galaxy, which is aligned with the radio axis,...

Searches for High Redshift Radio Galaxies (1997)

De Breuck, Carlos, Van Breugel, Wil, Rottgering, Huub, Miley, George

We have started a search for High Redshift Radio Galaxies (HZRGs) in an area covering 7 sr by selecting a sample of Ultra Steep Spectrum (USS) sources with a low flux density cut-off S(1400 MHz) > 10...

On the Origin of the UV Continuum Emission from the High Redshift Radio Galaxy 3C256 (1996)

Dey, Arjun, Cimatti, Andrea, Van Breugel, Wil, Antonucci, Robert, Spinrad, Hyron

We report spectropolarimetric observations obtained with the W.M. Keck Telescope of the high redshift z=1.824 aligned radio galaxy 3C256. Our observations confirm that the spatially extended UV...
