Emission line galaxies at z = 6.5
Jaron Kurk, Andrea Cimatti, Sperello di Serego Alighieri +2
We are carrying out a search for Lyman alpha emitting galaxies at z = 6.5 employing slitless spectroscopy at the VLT. In our 43 square arcminute field we find three isolated single…
BRIGHT lights, BIG city: Massive galaxies, giant Ly-a nebulae, and proto--clusters
W. van Breugel, M. Reuland, W. de Vries +10
High redshift radio galaxies are great cosmological tools for pinpointing the most massive objects in the early Universe: massive forming galaxies, active super--massive black hole…
A search for high redshift clusters associated with radio galaxies at 2 < z < 4
J. D. Kurk, B. P. Venemans, H. J. A. Roettgering +2
High redshift radio galaxies are amongst the most massive galaxies in the early Universe and have properties expected from central galaxies in forming clusters. We are carrying out…
Deep VLT spectroscopy of high redshift radio galaxy MRC 2104-242: Evidence for a metallicity gradient
R. Overzier, H. Rottgering, J. Kurk +1
In this contribution we will present deep VLT spectroscopy observations of the giant emission line halo around the z=2.49 radio galaxy MRC 2104-242. The morphology of the halo is d…
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…
