The host galaxy of the z=2.4 radio-loud AGN MRC 0406-244 as seen by HST

N. A. Hatch, H. J. A. Röttgering, G. K. Miley +7

We present multicolour Hubble Space Telescope images of the powerful z=2.4 radio galaxy MRC 0406-244 and model its complex morphology with several components including a host galax…

A z~3 radio galaxy and its protocluster: evidence for a superstructure?

E. Kuiper, B. P. Venemans, N. A. Hatch +2

We present spectroscopic follow-up observations of Lyman Break Galaxies (LBGs) selected in the field surrounding the radio galaxy MRC0316-257 at z~3.13 (0316). Robust spectroscopic…

A luminous quasar at a redshift of z = 7.085

Daniel J. Mortlock, Stephen J. Warren, Bram P. Venemans +14

The intergalactic medium was not completely reionized until approximately a billion years after the Big Bang, as revealed by observations of quasars with redshifts of less than 6.5…

Discovery of a high-z protocluster with tunable filters: the case of 6C0140+326 at z=4.4

E. Kuiper, N. A. Hatch, B. P. Venemans +7

We present the first results obtained using a tunable narrowband filter in the search for high-z protoclusters. Using the recently commissioned red tunable filter on the Gran Teles…

A SINFONI view of flies in the Spiderweb: a galaxy cluster in the making

E. Kuiper, N. A. Hatch, G. K. Miley +8

The environment of the high-z radio galaxy PKS 1138-262 at z~2.2 is a prime example of a forming galaxy cluster. We use deep SINFONI data to perform a detailed study of the kinemat…

H-alpha emitters in z~2 proto-clusters: evidence for faster evolution in dense environments

N. A. Hatch, J. D. Kurk, L. Pentericci +4

This is a study of H-alpha emitters in two dense galaxy proto-clusters surrounding radio galaxies at z~2. We show that the proto-cluster surrounding MRC 1138-262 contains 14+/-2 ti…

A galaxy populations study of a radio-selected protocluster at z~3.1

E. Kuiper, N. A. Hatch, H. J. A. Rottgering +12

We present a population study of several types of galaxies within the protocluster surrounding the radio galaxy MRC0316-257 at z~3.1. In addition to the known population of Ly_alph…
