Publikováno v: Astronomy & Astrophysics. 491:407-424

AGN feedback now appears as an attractive mechanism to resolve some of the outstanding problems with the "standard" cosmological models, in particular those related to massive galaxies. To directly constrain how this may influence the formation of ma

We present new constraints on the evolution of the early-type galaxy color-magnitude relation (CMR) based on deep near-infrared imaging of a galaxy protocluster at z=2.16 obtained using NICMOS on-board the Hubble Space Telescope. This field contains

Compact radio sources and jet-driven AGN feedback in the early universe: constraints from integral-field spectroscopy

Autor: C. De Breuck, Andrea M. Gilbert, Nicole P. H. Nesvadba, M. D. Lehnert, W. van Breugel

Publikováno v: Astronomy & Astrophysics. 475:145-153

To investigate the impact of radio jets during the formation epoch of their massive host galaxies, we present an analysis of two massive, log(M_stel/ M_sun)~10.6 and 11.3, compact radio galaxies at z=3.5, TNJ0205+2242 and TNJ0121+1320. Their small ra

Energetic Processing of Interstellar Silicate Grains by Cosmic Rays

While a significant fraction of silicate dust in stellar winds has a crystalline structure, in the interstellar medium nearly all of it is amorphous. One possible explanation for this observation is the amorphization of crystalline silicates by relat

AGN or starburst powered? Untangling the pan-spectral SEDsof the high-redshift radio galaxies and sub-mm galaxies

Autor: Brent Groves, H. Röttgering, W. van Breugel, Michael A. Dopita, Michiel Reuland

Publikováno v: Astronomische Nachrichten. 327:155-158

Here we show how theoretical pan-spectral modelling is beginning to decode the physical parameters of the interstellar medium of starburst and high-redshift galaxies, is revealing the star formation rate, identifying the bolometric contribution due t

High redshift Lyα halos

Autor: W. H. de Vries, H. J. A. Röttgering, C. De Breuck, Michael A. Dopita, Michiel Reuland, G. K. Miley, Steve Croft, W. van Breugel

Publikováno v: Astronomische Nachrichten. 327:175-179

We review current evidence for the existence of large emission-line halos around high redshift radio galaxies. Detailed narrow-band imaging and spectroscopic studies of these systems may help us understand the early stages of massive forming galaxies

Observations of the radio galaxy MRC 0316-257 at z=3.13 and the surrounding field are presented. Using narrow- and broad-band imaging obtained with the VLT, 77 candidate Ly-alpha emitters with a rest-frame equivalent width of > 15 A were selected in

Imaging and spectroscopy with the Very Large Telescope have revealed 20 Ly? emitters within a projected distance of 1.3 Mpc and 600 km s-1 of the luminous radio galaxy TN J1338-1942 at z = 4.1. Compared to the field density of Ly? emitters, this impl

Keck Adaptive Optics Observations of the Radio Galaxy 3C 294: A Merging System atz = 1.786?

Autor: W. van Breugel, A. Quirrenbach, W. H. de Vries, Krzysztof J. Fidkowski, J. E. Roberts

We present seeing-limited and adaptive optics (AO) images of the z = 1.786 radio galaxy 3C294 in the H and K' infrared bands obtained at Keck Observatory. The infrared emission of 3C294 is dominated by two distinct components separated by ~1" (9 kpc)
