Extreme ultra-soft X-ray variability in an eROSITA observation of the Narrow-Line Seyfert 1 Galaxy 1H 0707-495
Th. Boller, T. Liu, P. Weber +9
The ultra-soft narrow-line Seyfert 1 galaxy 1H 0707-495 is a well-known and highly variable active galactic nucleus (AGN), with a complex, steep X-ray spectrum, and has been studie…
The eROSITA X-ray telescope on SRG
P. Predehl, R. Andritschke, V. Arefiev +90
eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the primary instrument on the Spectrum-Roentgen-Gamma (SRG) mission, which was successfully launched on July 1…
An underlying clock in the extreme flip-flop state transitions of the black hole transient Swift J1658.2-4242
David Bogensberger, Gabriele Ponti, Chichuan Jin +8
Aims: Flip-flops are top-hat-like X-ray flux variations which occur in some transient accreting black hole binary systems and feature simultaneous changes in the spectral hardness…
Stellar mass -- halo mass relation for the brightest central galaxies of X-ray clusters since z~0.65
G. Erfanianfar, A. Finoguenov, K. Furnell +25
We present the brightest cluster galaxies (BCGs) catalog for SPectroscoic IDentification of eROSITA Sources (SPIDERS) DR14 cluster program value-added catalog. We list the 416 BCGs…
4MOST Consortium Survey 6: Active Galactic Nuclei
A. Merloni, D. A. Alexander, M. Banerji +17
X-ray and mid-infrared emission are signposts of the accretion of matter onto the supermassive black holes that reside at the centres of most galaxies. As a major step towards unde…
A dust-enshrouded tidal disruption event with a resolved radio jet in a galaxy merger
S. Mattila, M. Pérez-Torres, A. Efstathiou +33
Tidal disruption events (TDEs) are transient flares produced when a star is ripped apart by the gravitational field of a supermassive black hole (SMBH). We have observed a transien…
