The extended Northern ROSAT Galaxy Cluster Survey (NORAS II) I. Survey Construction and First Results
Hans Boehringer, Gayoung Chon, Joerg Retzlaff +3
As the largest, clearly defined building blocks of our Universe, galaxy clusters are interesting astrophysical laboratories and important probes for cosmology. X-ray surveys for ga…
A diversity of dusty AGN tori: Data release for the VLTI/MIDI AGN Large Program and first results for 23 galaxies
Leonard Burtscher, Klaus Meisenheimer, Konrad R. W. Tristram +9
The AGN-heated dust distribution (the "torus") is increasingly recognized not only as the absorber required in unifying models, but as a tracer for the reservoir that feeds the nuc…
Complete infrared spectral energy distributions of mm detected quasars at z>5
C. Leipski, K. Meisenheimer, F. Walter +7
We present Herschel far-infrared (FIR) photometry of eleven quasars at redshift z>5 that have previously been detected at 1.2mm. We perform full spectral energy distribution (SED)…
Tully-Fisher analysis of the multiple cluster system Abell 901/902
Benjamin Bösch, Asmus Böhm, Christian Wolf +7
We derive rotation curves from optical emission lines of 182 disk galaxies (96 in the cluster and 86 in the field) in the region of Abell 901/902 located at . We focus…
AGN host galaxies at redshift z~0.7: peculiar or not?
Asmus Boehm, Lutz Wisotzki, Eric F. Bell +21
We perform a quantitative morphological comparison between the hosts of Active Galactic Nuclei (AGN) and quiescent galaxies at intermediate redshifts (z~0.7). The imaging data are…
The Herschel view of the environment of the radio galaxy 4C+41.17 at z = 3.8
D. Wylezalek, J. Vernet, C. De Breuck +16
We present Herschel observations at 70, 160, 250, 350 and 500 micron of the environment of the radio galaxy 4C+41.17 at z = 3.792. About 65% of the extracted sources are securely i…
