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…
Cosmic hide and seek: the volumetric rate of X-ray quasi-periodic eruptions
R. Arcodia, A. Merloni, J. Buchner +6
Multi-wavelength extragalactic nuclear transients, particularly those detectable as multi-messengers, are among the primary drivers for the next-generation observatories. X-ray qua…
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 more the merrier: SRG/eROSITA discovers two further galaxies showing X-ray quasi-periodic eruptions
R. Arcodia, Z. Liu, A. Merloni +20
X-ray quasi-periodic eruptions (QPEs) are a novel addition to the group of extragalactic transients. In this work, we report the discovery of two further galaxies showing QPEs, eRO…
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…
