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 J234402.9 $-$ 352640; 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 J234402.9 $-$ 352640, was discovered in the second all-sky survey of SRG/eROSITA. The object brightened by a factor of at least 150 in…
