An X-ray flaring event and a variable soft X-ray excess in the Seyfert LCRS B040659.9-385922 as detected with eROSITA
S. Krishnan, A. G. Markowitz, M. Krumpe +13
Extreme continuum variability in AGNs can indicate extreme changes in accretion flows onto supermassive black holes. We explore the multiwavelength nature of a continuum flare in t…
The eROSITA Upper Limits: Description and access to the data
D. Tubín-Arenas, M. Krumpe, G. Lamer +13
The soft X-ray instrument eROSITA on board the Spectrum-Roentgen-Gamma (SRG) observatory has successfully completed four of the eight planned all-sky surveys, detecting almost one…
A radio flare associated with the nuclear transient eRASSt J234403-352640: an outflow launched by a potential tidal disruption event
A. J. Goodwin, G. E. Anderson, J. C. A. Miller-Jones +7
We present an extensive radio monitoring campaign of the nuclear transient eRASSt J234403-352640 with the Australia Telescope Compact Array, one of the most X-ray luminous TDE cand…
The SRG/eROSITA all-sky survey: First X-ray catalogues and data release of the western Galactic hemisphere
A. Merloni, G. Lamer, T. Liu +142
The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite began surveying the sky in December 2019, with the aim of producing all-sky X-ray source lists and sk…
Rapid evolution of the recurrence time in the repeating partial tidal disruption event eRASSt J045650.3-203750
Zhu Liu, Taeho Ryu, A. J. Goodwin +8
In this letter, we present the results from further X-ray and UV observations of the nuclear transient eRASSt J045650.3-203750 (hereafter J0456-20). We detected five repeating X-ra…
eROSITA Detection of a Cloud Obscuration Event in the Seyfert AGN EC 04570-5206
Alex Markowitz, Mirko Krumpe, David Homan +13
Recent years have seen broad observational support for the presence of a clumpy component within the circumnuclear gas around SMBHs. In the X-ray band, individual clouds can manife…
