Large-amplitude modulations and hours-timescale variability in the early X-ray light curve of a tidal disruption flare

A. Malyali, A. Rau, P. Baldini +11

We present new X-ray, optical, and UV observations of the tidal disruption event candidate eRASSt J234402.9-352640, (hereafter J2344). Between 50 and 60 days after peak optical bri…

Radio properties of the quasi-periodic eruption source RXJ1301.9+2747 at parsec scales

S. D. von Fellenberg, R. Arcodia, P. Benke +6

Quasi-periodic eruptions (QPEs) are repeating soft X-ray flares associated with galactic nuclei. Several recent works have found evidence that the accretion flow in the galactic nu…

GRB 241105A: A test case for GRB classification and rapid r-process nucleosynthesis channels

Dimple, B. P. Gompertz, A. J. Levan +85

Gamma-ray bursts (GRBs) offer a powerful window to probe the progenitor systems responsible for the formation of heavy elements through the rapid neutron capture (r-) process, than…

SRG/eROSITA No. 5: Discovery of quasi-periodic eruptions every ~3.7 days from a galaxy at z>0.1

R. Arcodia, P. Baldini, A. Merloni +17

Quasi-periodic eruptions (QPEs) are repeating soft X-ray bursts from the nuclei of galaxies, tantalizingly proposed to be extreme mass ratio inspirals. Here, we report the discover…

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…

A systematic analysis of the radio properties of 22 X-ray selected tidal disruption event candidates with the Australia Telescope Compact Array

A. J. Goodwin, M. Burn, G. E. Anderson +7

We present a systematic analysis of the radio properties of an X-ray selected sample of tidal disruption event (TDE) candidates discovered by the eROSITA telescope. We find radio s…
