The ROSAT view of NGC 1365 and the luminous highly variable off-nuclear X-ray source NGC 1365 - X1
Stefanie Komossa, Hartmut Schulz
We present an X-ray spectral and spatial analysis of the composite starburst/Seyfert galaxy NGC 1365. Excellent fits of the ROSAT PSPC spectrum are obtained by combining a soft the…
The ROSAT view of NGC 1365: core emission, the highly variable source NGC 1365--X1 and alignments of surrounding X-ray sources
Stefanie Komossa, Hartmut Schulz
We present a spectral and spatial analysis of the nuclear and circumnuclear X-ray emission of the prominent southern starburst/Seyfert galaxy NGC 1365. To describe the X-ray spectr…
The ULIRG NGC 6240: Luminous extended X-ray emission and evidence for an AGN
Hartmut Schulz, Stefanie Komossa, Jochen Greiner
We briefly review and extend our discussion of the ROSAT detection of the extraordinarily luminous (>10^{42} erg/s) partly extended (> 30 kpc diameter) X-ray emission from the doub…
ROSAT HRI discovery of luminous extended X-ray emission in NGC 6240
Stefanie Komossa, Hartmut Schulz, Jochen Greiner
We report the detection of luminous extended X-ray emission in NGC 6240 on the basis of ROSAT HRI observations of this ultraluminous IR galaxy. The spatial structure and temporal b…
