Spatially extended absorption around the z=2.63 radio galaxy MRC 2025-218: outflow or infall?
A. Humphrey, M. Villar-Martin, S. F. Sanchez +7
We present an investigation into the absorber in front of the z=2.63 radio galaxy MRC 2025-218, using integral field spectroscopy obtained at the Very Large Telescope, and long sli…
The Great Observatories Origins Deep Survey. VLT/VIMOS Spectroscopy in the GOODS-South Field
P. Popesso, M. Dickinson, M. Nonino +10
We present the first results of the VIsible Multiobject Spectrograph (VIMOS) ESO/GOODS program of spectroscopy of faint galaxies in the Chandra Deep Field South (CDF-S). The progra…
Deep spectroscopy of the FUV-optical emission lines from a sample of radio galaxies at z~2.5: metallicity and ionization
A. Humphrey, M. Villar-Martin, J. Vernet +3
We present long-slit NIR spectra, obtained using the ISAAC instrument at the Very Large Telescope, for nine radio galaxies at z~2.5. One-dimensional spectra have been extracted and…
UV and optical emission lines from the z=2.6 radio galaxy 0828+193: spatially resolved measurements
A. Humphrey, F. Iwamuro, M. Villar-Martin +3
We present an investigation into the spatial variation of the rest-frame UV and optical line and continuum emission along the radio axis of the z=2.6 radio galaxy 0828+193, using l…
Report on the ESO Workshop "Obscured AGN Across Cosmic Time" held at Kloster Seeon, Bavaria, 5 to 8 June 2007
Robert Fosbury, Carlos De Breuck, Vincenzo Mainieri +2
While the radio-loud, obscured quasars (the radio galaxies) have been known and studied for decades, new and sensitive X-ray and mid-infrared surveys are now beginning to reveal la…
Ly-alpha excess in high redshift radio galaxies: a signature of star formation
M. Villar-Martin, A. Humphrey, C. De Breuck +3
About 54% of radio galaxies at z>3 and 8% of radio galaxies at 2<z<3 show unusually strong Ly-alpha emission, compared with the general population of high redshift (z>2) radio gala…
