Spectroscopy of Ultra Steep Spectrum Radio Sources
Carlos De Breuck, Wil van Breugel, Huub Rottgering +6
We present optical spectroscopy of 62 objects selected from several samples of ultra steep spectrum (USS) radio sources. 46 of these are from our primary catalog, consisting of 669…
High redshift radio galaxies: Beacons to biased hierarchical galaxy formation within large scale structure
C. L. Carilli, G. K. Miley, H. Rottgering +6
We summarize observations of the properties of powerful radio galaxies and their environments from z = 0 to 5. These data show that some high redshift radio galaxies inhabit region…
A search for clusters at high redshift - II. A proto cluster around a radio galaxy at z=2.16
L. Pentericci, J. D. Kurk, H. J. A Rottgering +7
VLT spectroscopic observations of Ly alpha--excess objects in the field of the clumpy radio galaxy 1138-262 at z=2.16 have led to the discovery of 14 galaxies and one QSO at approx…
Search for clusters at high redshift - I. Candidate Lya emitters near 1138-262 at z=2.2
J. D. Kurk, H. J. A. Rottgering, L. Pentericci +7
Radio, optical and X-ray observations of the powerful radio galaxy PKS 1138-262 at z=2.156 have suggested that this galaxy is a massive galaxy in the center of a forming cluster. W…
A vestige low metallicity gas shell surrounding the radio galaxy 0943-242 at z=2.92
L. Binette, J. D. Kurk, M. Villar-Martin +1
Observations are presented showing the doublet CIV 1550 absorption lines superimposed on the CIV emission in the radio galaxy 0943-242. Within the errors, the redshift of the absor…
The rise and fall of V4334 Sgr (Sakurai's Object)
H. W. Duerbeck, W. Liller, C. Sterken +10
CCD UBVRi photometry of the final helium flash object V4334 Sgr (Sakurai's Object), carried out during 1997 - 1999, is presented, and the light curve from its pre-discovery rise to…
