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…
Observational evidence for supermassive black hole binaries
Stefanie Komossa
Coalescing massive black hole binaries are powerful emitters of gravitational waves, in the LISA sensitivity range for masses M_BH ~ 10^{4-7} M_sun. According to hierarchical galax…
An AGN Sample with High X-ray-to-optical Flux Ratio from RASS II.Optical Emission Line Properties of Seyfert 1 Type AGN
D. W. Xu, Stefanie Komossa, J. Y. Wei +2
This work studies the optical emission line properties of a sample of 155 low-redshift bright X-ray selected ROSAT Seyfert~1 type AGN for which adequate signal-to-noise ratio spect…
X-ray imaging and spectroscopy of (radio-quiet) AGN: Highlights from Chandra and XMM-Newton
Stefanie Komossa
The X-ray observatories XMM-Newton and Chandra provided a wealth of exciting new results. Chandra delivered X-ray images of outstanding detail, reaching subarcsecond spatial resolu…
