Intra-Group Light in Hickson Compact Groups - A Wavelet Approach
Cristiano Da Rocha, Claudia Mendes de Oliveira, Bodo L. Ziegler
A diffuse component of intra-group light can be observed in compact groups of galaxies. This component is presumably due to stellar material tidally stripped from the member galaxi…
The Evolution of Field Spiral Galaxies over the Past 8 Gyr
Asmus Boehm, Bodo L. Ziegler
We have performed a large observing campaign of intermediate-redshift disk galaxies including spectroscopy with the FORS instruments of the VLT and imaging with the Advanced Camera…
Disk galaxy evolution up to redshift z=1
Asmus Boehm, Bodo L. Ziegler
We have performed intermediate-resolution VLT/FORS spectroscopy and HST/ACS imaging of 129 field spiral galaxies within the FORS Deep Field. The galaxies cover the redshift range 0…
Chemical and mass evolution of galaxies
Bodo L. Ziegler
An introduction is given to projects investigating galaxy evolution quantitatively by spectroscopic observations of very distant galaxies that have weak apparent brightnesses and s…
Early-type Galaxies in the Cluster Abell 2390 at z=0.23
A. Fritz, B. L. Ziegler, R. G. Bower +2
To examine the evolution of the early-type galaxy population in the rich cluster Abell 2390 at z=0.23 we have gained spectroscopic data of 51 elliptical and lenticular galaxies wit…
VLT spectroscopy of globular cluster in NGC 3115
Harald Kuntschner, Bodo L. Ziegler, R. M. Sharples +2
We present results derived from VLT-FORS2 spectra of 17 globular clusters associated with the nearby lenticular galaxy NGC3115. Comparing line-strength indices to new stellar popul…
