Galaxy Evolution in Dense Environments: Properties of Interacting Galaxies in the A901/02 Supercluster
A. L. Heiderman, S. Jogee, D. J. Bacon +23
We present a study of galaxies in the STAGES survey of the Abell 901/902 supercluster at z~0.165, based on HST ACS F606W, COMBO-17, Spitzer 24um, XMM-Newton X-ray, and gravitationa…
A hole in the sky - The dependence of the galaxy luminosity function on the environment
S. Phleps, C. Wolf, J. A. Peacock +2
We have developed a method to calculate overdensities in multicolour surveys, and compare the local density contrast measured in galaxy samples with different redshift error distri…
Evolution of optically faint AGN from COMBO-17 and GEMS
L. Wisotzki, K. Jahnke, S. F. Sanchez +13
We have mapped the AGN luminosity function and its evolution between z=1 and z=5 down to apparent magnitudes of . Within the GEMS project we have analysed HST-ACS images of m…
Constraints to the evolution of Ly-Alpha bright galaxies between z=3 and z=6
C. Maier, K. Meisenheimer, E. Thommes +6
Galaxies at high redshift with a strong Ly-Alpha emission line trace massive star formation in the absence of dust, and can therefore be regarded as a prime signature of the first…
Probing the distribution of dark matter in the Abell 901/902 supercluster with weak lensing
M. E. Gray, A. N. Taylor, K. Meisenheimer +3
We present a weak shear analysis of the Abell 901/902 supercluster, composed of three rich clusters at z=0.16. Using a deep R-band image from the 0.5 x 0.5 degree MPG/ESO Wide Fiel…
Object Classification in Astronomical Multi-Color Surveys
C. Wolf, K. Meisenheimer, H. -J. Röser
We present a photometric method for identifying stars, galaxies and quasars in multi-color surveys, which uses a library of >65000 color templates. The method aims for extracting t…
