The galaxy population of the complex cluster system Abell 3921
Florian Pranger, Asmus Böhm, Chiara Ferrari +6
We present a spectrophotometric analysis of the galaxy pop. in the area of the merging cluster Abell 3921 at redshift 0.093. We investigate the impact of the complex cluster enviro…
Age-dating the Tully-Fisher relation at moderate redshift
Ignacio Ferreras, Asmus Böhm, Bodo Ziegler +1
We analyse the Tully-Fisher relation at moderate redshift from the point of view of the underlying stellar populations, by comparing optical and NIR photometry with a phenomenologi…
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…
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…
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.…
