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…
ASKAP J005512.2-255834: A Luminous, Long-Lived Radio Transient at z = 0.1 -- an Orphan Afterglow or an off-nuclear TDE from an IMBH?
Ashna Gulati, Tara Murphy, David L. Kaplan +24
We report the discovery of a slowly evolving, extragalactic radio transient, ASKAP J005512.2--255834 (hereafter ASKAP J0055-2558), identified using the Australian SKA Pathfinder in…
The 6 year radio lightcurve of the tidal disruption event AT2019azh
Matthew Burn, Adelle J. Goodwin, Gemma E. Anderson +5
Analysis of radio emission from tidal disruption events allows for detailed constraints on the properties of ejected outflows and the host environment surrounding the black hole. H…
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…
The population of tidal disruption events discovered with eROSITA
Iuliia Grotova, Arne Rau, Pietro Baldini +13
This paper presents a systematic study of X-ray-selected canonical tidal disruption events (TDEs) discovered in the western Galactic hemisphere of the first two eROSITA all-sky sur…
A second radio flare from the tidal disruption event AT2020vwl: a delayed outflow ejection?
A. J. Goodwin, A. Mummery, T. Laskar +12
We present the discovery of a second radio flare from the tidal disruption event (TDE) AT2020vwl via long-term monitoring radio observations. Late-time radio flares from TDEs are b…
