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…
