The rebrightening of a ROSAT-selected tidal disruption event: repeated weak partial disruption flares from a quiescent galaxy?
A. Malyali, Z. Liu, A. Rau +11
The ROSAT-selected tidal disruption event (TDE) candidate RX J133157.6-324319.7 (J1331), was detected in 1993 as a bright (0.2-2 keV flux of erg s$^…
eRASSt J074426.3+291606: prompt accretion disc formation in a 'faint and slow' tidal disruption event
A. Malyali, Z. Liu, A. Merloni +10
We report on multi-wavelength observations of the tidal disruption event (TDE) candidate eRASSt J074426.3+291606 (J0744), located in the nucleus of a previously quiescent galaxy at…
Obscuration-dependent evolution of Active Galactic Nuclei
Johannes Buchner, Antonis Georgakakis, Kirpal Nandra +9
We aim to constrain the evolution of AGN as a function of obscuration using an X-ray selected sample of AGN from a multi-tiered survey including the CDFS, AEGIS-XD, COSM…
On the Fe K absorption - accretion state connection in the Galactic center neutron star X-ray binary AX J1745.6-2901
G. Ponti, S. Bianchi, T. Munoz-Darias +17
AX J1745.6-2901 is a high-inclination (eclipsing) neutron star Low Mass X-ray Binary (LMXB) located less than ~1.5 arcmin from Sgr A*. Ongoing monitoring campaigns have targeted Sg…
A fast and long-lived outflow from the supermassive black hole in NGC 5548
J. S. Kaastra, G. A. Kriss, M. Cappi +31
Supermassive black holes in the nuclei of active galaxies expel large amounts of matter through powerful winds of ionized gas. The archetypal active galaxy NGC 5548 has been studie…
Compton thick active galactic nuclei in Chandra surveys
Murray Brightman, Kirpal Nandra, Mara Salvato +2
We present the results from an X-ray spectral analysis of active galactic nuclei (AGN) in the Chandra Deep Field-South, AEGIS-XD and Chandra-COSMOS surveys, focussing on the identi…
