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-…
