The extended Northern ROSAT Galaxy Cluster Survey (NORAS II) I. Survey Construction and First Results
Hans Boehringer, Gayoung Chon, Joerg Retzlaff +3
As the largest, clearly defined building blocks of our Universe, galaxy clusters are interesting astrophysical laboratories and important probes for cosmology. X-ray surveys for ga…
The Great Observatories Origins Deep Survey - VLT/ISAAC Near-Infrared Imaging of the GOODS-South Field
J. Retzlaff, P. Rosati, M. Dickinson +5
We present the final public data release of the VLT/ISAAC near-infrared imaging survey in the GOODS-South field. The survey covers an area of 172.5, 159.6 and 173.1 arcmin^2 in the…
HD 77407 and GJ 577: two new young stellar binaries detected with the Calar Alto Adaptive Optics system ALFA
M. Mugrauer, R. Neuhäuser, E. W. Guenther +9
We present the first results from our search for close stellar and sub-stellar companions to young nearby stars on the northern sky. Our infrared imaging observations are obtained…
Searching for X-ray Galaxy Clusters in the Zone of Avoidance
H. Boehringer, P. Schuecker, S. Komossa +3
Based on the ROSAT All-Sky Survey we are constructing a sample of the X-ray brightest galaxy clusters for cosmological studies. We have already completed the compilation of a sampl…
Constraining cosmological models with cluster power spectra
J. Retzlaff, S. Borgani, S. Gottloeber +2
Using extensive N-body simulations we estimate redshift space power spectra of clusters of galaxies for different cosmological models (SCDM, TCDM, CHDM, Lambda-CDM, OCDM, BSI, tau-…
