Galactic SNR candidates in the ROSAT all-sky survey
Daniel Schaudel, Werner Becker, Wolfgang Voges +3
Identified radio supernova remnants (SNRs) in the Galaxy comprise an incomplete sample of the SNR population due to various selection effects. ROSAT performed the first all-sky sur…
Identification of a complete sample of northern ROSAT All-sky survey X-ray sources. VII. The AGN subsample
I. Appenzeller, F. -J. Zickgraf, J. Krautter +1
In order to derive statistical properties of a complete X-ray selected sample of AGN we used the classification spectra of the RASS Selected Areas-North survey to study the luminos…
Search for GRB X-ray afterglows in the ROSAT all-sky survey
J. Greiner, D. H. Hartmann, W. Voges +3
We describe a search for X-ray afterglows from gamma-ray bursts using the ROSAT all-sky survey (RASS) data. If the emission in the soft X-ray band is significantly less beamed than…
Probing the Cosmic Large-Scale Structure with the REFLEX Cluster Survey : Profile of an ESO Key Programme
H. Böhringer, L. Guzzo, C. A. Collins +11
The paper describes the goals and first results of the ROSAT ESO Flux-Limited X-ray (REFLEX) Cluster Survey, a redshift survey of the X-ray brightest galaxy clusters in the ROSAT A…
On the evolutionary behaviour of BL Lac objects
N. Bade, V. Beckmann, N. G. Douglas +5
We present a new well defined sample of BL Lac objects selected from the ROSAT All-Sky Survey (RASS). The sample consists of 39 objects with 35 forming a flux limited sample down t…
