On the X-ray emission of z~2 radio galaxies: IC scattering of the CMB & no evidence for fully-formed potential wells
R. A. Overzier, D. E. Harris, C. L. Carilli +3
We present the results of 20 ksec Chandra observations for each of 5 radio galaxies in the redshift range 2.0 < z < 2.6. For 4 of the 5 targets we detect unresolved X-ray component…
A search for clusters at high redshift - IV. Spectroscopy of H-alpha emitters in a proto-cluster at z=2.16
J. D. Kurk, L. Pentericci, R. A. Overzier +2
Radio galaxy PKS 1138-262 is a massive galaxy at z=2.16, located in a dense environment. We have found an overdensity of Ly-alpha emitting galaxies in this field, consistent with a…
A search for clusters at high redshift - III. Candidate H-alpha emitters and EROs in the PKS 1138-262 proto-cluster at z=2.16
J. D. Kurk, L. Pentericci, H. J. A. Roettgering +1
In this paper we present deep VLT multi wavelength imaging observations of the field around the radio galaxy PKS 1138-262 aimed at detecting and studying a (potential) proto-cluste…
Clustering and Proto-Clusters in the Early Universe
Huub Rottgering, Carlos De Breuck, Emanuele Daddi +5
The clustering properties of clusters, galaxies and AGN as a function of redshift are briefly discussed. It appears that extremely red objects at z ~ 1, and objects with J-K > 1.7…
