Winds and Outflows in Starburst Galaxies and AGN
Stefanie Komossa, Guenther Hasinger, Hartmut Schulz
Winds and outflows in starburst galaxies and AGN provide important information on the physics of the "central engine", the presence and evolution of (nuclear) starbursts, and the m…
Formation of Massive Black Holes in Early Mergers ?
Hartmut Schulz, Stefanie Komossa
We review theoretical and observational arguments favoring a scenario in which a typical massive black hole (MBH) is formed in the merger core of colliding disk systems at high z d…
The nature of the luminous X-ray emission of NGC 6240
Stefanie Komossa, Hartmut Schulz
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 ult…
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…
