A new Bowen Fluorescence Flare and Extreme Coronal Line Emitter discovered by SRG/eROSITA
Pietro Baldini, Arne Rau, Riccardo Arcodia +19
The nuclear transient eRASSt J012026.5-292727 (J012026 hereafter) was discovered in the second SRG/eROSITA all-sky survey (eRASS2). The source appeared more than one order of magni…
Repeating transients in galactic nuclei: confronting observations with theory
Petra Suková, Francesco Tombesi, Dheeraj R. Pasham +5
In the last few years, a mysterious new class of astrophysical objects has been uncovered. These are spatially coincident with the nuclei of external galaxies and show X-ray variat…
Fragments of harmony amid apparent chaos: a closer look at the X-ray quasi-periodic eruptions of the galaxy RX J1301.9+2747
Margherita Giustini, Giovanni Miniutti, Riccardo Arcodia +17
Quasi-periodic eruptions (QPEs) are an extreme X-ray variability phenomenon associated with low-mass supermassive black holes. First discovered in the nucleus of the galaxy GSN 069…
Repeating partial disruptions and two-body relaxation
Luca Broggi, Nicholas C. Stone, Taeho Ryu +4
Two-body relaxation may drive stars onto near-radial orbits around a massive black hole, resulting in a tidal disruption event (TDE). In some circumstances, stars are unlikely to u…
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…
