New NLS1 galaxies detected among RASS galaxies
W. Pietsch, K. Bischoff, Th. Boller
Six Narrow-Line Seyfert 1 galaxies have been discovered in optical follow-up spectroscopy of nuclei of galaxies selected for their high X-ray flux in the ROSAT All Sky Survey. We g…
Properties of new X-ray selected AGN
K. Bischoff, W. Pietsch, T. Boller +3
We present the results of a program to identify so far unknown active nuclei (AGN) in galaxies. Candidate galactic nuclei have been selected for optical spectroscopy from a cross-c…
New active galactic nuclei detected in ROSAT All Sky Survey galaxies; Part I: Verification of selection strategy
W. Pietsch, Th. Boller, S. Doebereiner +3
We present the first results of a program to identify so far unknown active nuclei (AGN) in galaxies. Candidate galactic nuclei have been selected for optical spectroscopy from a c…
X-Ray Binary Systems in the Small Magellanic Cloud
P. Kahabka, W. Pietsch
We present the result of a systematic search for spectrally hard and soft X-ray binary systems in the Small Magellanic Cloud (SMC). This search has been applied to ROSAT PSPC data…
