The FORS Deep Field Spectroscopic Survey

S. Noll, D. Mehlert, I. Appenzeller +10

We present a catalogue and atlas of low-resolution spectra of a well defined sample of 341 objects in the FORS Deep Field. All spectra were obtained with the FORS instruments at th…

Quasar Elemental Abundances at High Redshifts

M. Dietrich, F. Hamann, J. C. Shields +5

We examine rest-frame ultraviolet spectra of 70 high redshift quasars (z>3.5) to study the chemical enrichment history of the gas closely related to the quasars, and thereby estima…

The evolution of the Tully-Fisher relation of spiral galaxies

B. L. Ziegler, A. Boehm, K. J. Fricke +12

We present the B-band Tully-Fisher relation (TFR) of 60 late-type galaxies with redshifts 0.1-1. The galaxies were selected from the FORS Deep Field with a limiting magnitude of R=…

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…

Evidence for chemical evolution in the spectra of high redshift galaxies

D. Mehlert, S. Noll, I. Appenzeller +14

Using a sample of 57 VLT FORS spectra in the redshift range 1.37<z<3.40 (selected mainly from the FORS Deep Field survey) and a comparison sample with 36 IUE spectra of local (z ~…

The FORS Deep Field: Field selection, photometric observations and photometric catalog

J. Heidt, I. Appenzeller, A. Gabasch +21

The FORS Deep Field project is a multi-colour, multi-object spectroscopic investigation of an approx. 7 times 7 region near the south galactic pole based mostly on observations car…

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…

Discovery of an Optical Jet in the BL Lac Object 3C 371

K. Nilsson, J. Heidt, T. Pursimo +3

We have detected an optical jet in the BL Lac object 3C 371 that coincides with the radio jet in this object in the central few kpc. The most notable feature is a bright optical kn…

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…

astro-ph2005

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

A. Gabasch, U. Hopp, G. Feulner +12

We present the redshift evolution of the restframe galaxy luminosity function (LF) in the red r', i', and z' bands as derived from the FORS Deep Field (FDF). Using the deep and hom…

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…

Internal kinematics of spiral galaxies in distant clusters. Part II. Observations and data analysis

K. Jaeger, B. L. Ziegler, A. Boehm +5

We have conducted an observing campaign with FORS at the ESO-VLT to explore the kinematical properties of spiral galaxies in distant galaxy clusters. Our main goal is to analyse tr…

The FORS Deep Field

J. Heidt, I. Appenzeller, R. Bender +20

Dedicating a major fraction of its guaranteed time, the FORS consortium established a FORS Deep Field which contains a known QSO at z = 3.36. It was imaged in UBgRIz with FORS at t…

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…

Internal Kinematics of Spiral Galaxies in Distant Clusters

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

We present first results from our project to examine the internal kinematics of disk galaxies in 7 rich clusters with 0.3<=z<0.6. Spatially resolved MOS spectra have been obtained…
