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…
The ROSAT All-Sky Survey Bright Source Catalogue
Wolfgang Voges, Bernd Aschenbach, Thomas Boller +16
We present the ROSAT All-Sky Survey Bright Source Catalogue (RASS-BSC, revision 1RXS) derived from the all-sky survey performed during the first half year (1990/91) of the ROSAT mi…
Soft X-ray properties of Ultraluminous IRAS Galaxies
Th. Boller
A sample of 323 Ultraluminous IRAS galaxies (ULIRGs) has been correlated with the ROSAT All-Sky Survey and ROSAT public pointed observations. 22 objects are detected in ROSAT surve…
An ASCA observation of the radio-loud narrow-line Seyfert 1 galaxy RGB J0044+193
J. Siebert, K. M. Leighly, S. A. Laurent-Muehleisen +3
We present the results of an ASCA observation of the radio-loud NLS1 galaxy RGB J0044+193. The X-ray data are complemented by radio observations and a new optical spectrum for this…
