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…
Chemically consistent evolution of galaxies: galaxy models compared to DLA systems
Ulrich Lindner, Uta Fritze -- von Alvensleben, Klaus J. Fricke
We have extended our chemical and cosmological galaxy evolution model to calculate the abundance evolution for altogether 16 different elements in spiral galaxies in a chemically c…
X-rays from Interacting and Merging Galaxies
K. J. Fricke, P. Papaderos
We have used ROSAT PSPC and HRI to study the properties of the soft X-ray emission in a sample of colliding starburst galaxies. Together with data from other spectral ranges (optic…
X-rays from Blue Compact Dwarf Galaxies
P. Papaderos, K. J. Fricke
We present first results of a study devoted to the analysis of the X-ray emission as tracer of activity and diagnostic tool for the structural properties of Blue Compact Dwarf Gala…
