Relating basic properties of bright early-type dwarf galaxies to their location in Abell 901/902
F. D. Barazza, C. Wolf, M. E. Gray +20
We present a study of the population of bright early-type dwarf galaxies in the multiple-cluster system Abell 901/902. We use data from the STAGES survey and COMBO-17 to investigat…
Interacting Galaxies in the A901/902 Supercluster with STAGES
A. L. Heiderman, S. Jogee, I. Marinova +22
We present a study of galaxy mergers and the influence of environment in the Abell 901/902 supercluster at z~0.165. We use HST ACS F606W data from the STAGES survey, COMBO-17, Spit…
Low redshift AGN in the Hamburg/ESO Survey: I. The local AGN luminosity function
Andreas Schulze, Lutz Wisotzki, Bernd Husemann
We present a determination of the local (z=0) luminosity function of optically selected type 1 (broad-line) Active Galactic Nuclei. Our primary resource is the Hamburg/ESO Survey (…
Less than 10 percent of star formation in z=0.6 massive galaxies is triggered by major interactions
Aday R. Robaina, Eric F. Bell, Rosalind E. Skelton +26
Both observations and simulations show that major tidal interactions or mergers between gas-rich galaxies can lead to intense bursts of starformation. Yet, the average enhancement…
The role of black holes in galaxy formation and evolution
A. Cattaneo, S. M. Faber, J. Binney +14
Virtually all massive galaxies, including our own, host central black holes ranging in mass from millions to billions of solar masses. The growth of these black holes releases vast…
The QSO HE0450-2958: Scantily dressed or heavily robed? A normal quasar as part of an unusual ULIRG
Knud Jahnke, David Elbaz, Eric Pantin +5
(Abridged) The luminous z=0.286 quasar HE0450-2958 is interacting with a companion galaxy at 6.5 kpc distance and the whole system is a ULIRG. A so far undetected host galaxy trigg…
Optically-passive spirals: The missing link in gradual star formation suppression upon cluster infall
Christian Wolf, Alfonso Aragón-Salamanca, Michael Balogh +22
Galaxies migrate from the blue cloud to the red sequence when their star formation is quenched. Here, we report on galaxies quenched by environmental effects and not by mergers or…
Barred Galaxies in the Abell 901/2 Supercluster with STAGES
I. Marinova, S. Jogee, A. Heiderman +23
We present a study of bar and host disk evolution in a dense cluster environment, based on a sample of ~800 bright (MV <= -18) galaxies in the Abell 901/2 supercluster at z~0.165.…
History of Galaxy Interactions and their Impact on Star Formation over the Last 7 Gyr from GEMS
Shardha Jogee, Sarah H. Miller, Kyle Penner +22
We perform a comprehensive estimate of the frequency of galaxy mergers and their impact on star formation over z~0.24--0.80 (lookback time T_b~3--7 Gyr) using 3698 (M*>=1e9 Msun) g…
