Cataclysmic Variables from SDSS III. The Third Year
Paula Szkody, Arne Henden, Oliver Fraser +17
This paper continues the series that identifies new cataclysmic variables found in the Sloan Digital Sky Survey. We present 36 cataclysmic variables and one possible symbiotic star…
ROSAT-SDSS Galaxy Clusters Survey. Correlating X-ray and optical properties
P. Popesso, H. Boehringer, W. Voges
For a detailed comparison of the appearance of cluster of galaxies in X-rays and in the optical, we have compiled a comprehensive database of X-ray and optical properties of a samp…
Star-Forming Galaxies in the Sloan Digital Sky Survey -- The View from Pittsburgh
Regina E. Schulte-Ladbeck, Christopher J. Miller, Ulrich Hopp +4
We used data from the Data Release 1 (DR1) of the Sloan Digital Sky Survey (SDSS) in order to define a catalog of about 13,000 star-forming galaxies (SFG). We discuss the results o…
Selection of extragalactic Targets for AO and VLTI Observations
J. Zuther, A. Eckart, W. Voges +2
In this contribution we would like to emphasize the usefulness of data mining multiwavelength surveys like the Sloan Digital Sky Survey (SDSS) or the ROSAT All Sky Survey (RASS) --…
The REFLEX Galaxy Cluster Survey IV: The X-ray Luminosity Function
H. Boehringer, C. A. Collins, L. Guzzo +10
The X-ray galaxy cluster sample from the REFLEX Cluster Survey, which covers the X-ray brightest galaxy clusters detected in the ROSAT All-Sky Survey in the southern sky, is used t…
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…
