Internal kinematics of spiral galaxies in distant rich galaxy clusters

K. Jaeger, A. Boehm, B. L. Ziegler +2

We present our project on galaxy evolution in the environment of distant rich clusters aiming at disentangling the importance of specific interaction and galaxy transformation proc…

Star formation activity of intermediate redshift cluster galaxies out to the infall regions

B. Gerken, B. Ziegler, M. Balogh +3

We present a spectroscopic analysis of two galaxy clusters out to ~4Mpc at z~0.2. The two clusters VMF73 and VMF74 identified by Vikhlinin et al. (1998) were observed with MOSCA at…

The evolution of the luminosity functions in the FORS Deep Field from low to high redshift: I. The blue bands

A. Gabasch, R. Bender, S. Seitz +13

We use the very deep and homogeneous I-band selected dataset of the FORS Deep Field (FDF) to trace the evolution of the luminosity function over the redshift range 0.5 < z < 5.0. W…

PKS 0537-441: extended [O II] emission and a binary QSO?

J. Heidt, K. Jaeger, K. Nilsson +3

We present high-resolution imaging and low-resolution spectroscopy of the BL Lac object PKS 0537-441 (z = 0.893) and its environment. The observations were designed to clarify, whe…

Elemental Abundances in the Broad Emission Line Region of Quasars at Redshifts larger than 4

M. Dietrich, I. Appenzeller, F. Hamann +4

We present observations of 11 high redshift quasars ($3.9 \la z \la 5.0$) observed with low spectral resolution in the restframe ultraviolet using FORS 1 at the VLT UT 1. The emiss…

Environments of QSOs at intermediate redshifts

Klaus Jaeger, Klaus J. Fricke, Jochen Heidt

A preliminary analysis of fields around 20 mainly radio-quiet QSOs (RQQs) at intermediate redshift is summarized. We find overdensities of faint sources around 50% of our observed…
