Transient fading X-ray emission detected during the optical rise of a tidal disruption event

A. Malyali, A. Rau, C. Bonnerot +9

We report on the SRG/eROSITA detection of ultra-soft ( eV) X-ray emission ( erg s) from the tidal disruptio…

Multiwavelength study of extreme variability in LEDA 1154204: A changing-look event in a type 1.9 Seyfert

T. Saha, A. Markowitz, D. Homan +16

Context. Multiwavelength studies of transients in actively accreting supermassive black holes have revealed that large-amplitude variability is frequently linked to significant cha…

Discovery of the luminous X-ray ignition eRASSt J234402.9352640; I. Tidal disruption event or a rapid increase in accretion in an active galactic nucleus?

D. Homan, M. Krumpe, A. Markowitz +17

In November 2020, a new, bright object, eRASSt J234402.9352640, was discovered in the second all-sky survey of SRG/eROSITA. The object brightened by a factor of at least 150 in…

The rebrightening of a ROSAT-selected tidal disruption event: repeated weak partial disruption flares from a quiescent galaxy?

A. Malyali, Z. Liu, A. Rau +11

The ROSAT-selected tidal disruption event (TDE) candidate RX J133157.6-324319.7 (J1331), was detected in 1993 as a bright (0.2-2 keV flux of erg s$^…

eRASSt J074426.3+291606: prompt accretion disc formation in a 'faint and slow' tidal disruption event

A. Malyali, Z. Liu, A. Merloni +10

We report on multi-wavelength observations of the tidal disruption event (TDE) candidate eRASSt J074426.3+291606 (J0744), located in the nucleus of a previously quiescent galaxy at…
