The nature of the luminous X-ray emission of NGC 6240
Stefanie Komossa, Hartmut Schulz
Abstract
We briefly review and extend our discussion of the ROSAT detection of the extraordinarily luminous (> 1042 erg/s) partly extended (> 30 kpc diameter) X-ray emission from the ultraluminous infrared galaxy NGC 6240. The `standard'-model of starburst outflow is contrasted with alternatives and a comparison with the X-ray properties of ellipticals is performed.
