After a star has been tidally disrupted by a black hole, the debris forms an elongated stream.
We start by studying the evolution of this gas before its bound part returns to the original …

The majority of massive black holes (MBHs) likely hosted gas discs during their lifetimes.
These could either be long-lived active galactic nuclei (AGN) discs, or shorter-lived discs …

A fraction of tidal disruption events (TDEs) occur in active galactic nuclei (AGNs) whose
black holes possess accretion disks; these TDEs can be confused with common AGN flares …

When a star comes too close to a supermassive black hole, it gets torn apart by strong tidal
forces in a tidal disruption event, or TDE. Half of the elongated stream of debris comes back …

We present continued radio and X-ray observations of the relativistic tidal disruption event
Swift J164449. 3+ 573451 extending to δt≈ 2000 days after discovery. The radio data were …

After the tidal disruption of a star by a massive black hole, disrupted stellar debris can fall
back to the hole at a rate significantly exceeding its Eddington limit. To understand how …

The joint observation of GW170817 and GRB 170817A indicated that short gamma-ray
bursts (SGRBs) can originate from binary neutron star mergers. Moreover, some SGRBs …

We report the discovery of a tidal disruption event (TDE) candidate occurring in the active
galactic nucleus (AGN) SDSS J022700. 77-042020.6. A sudden increase in flux from J0227 …

In the manuscript, effects of tidal disruption events (TDEs) are estimated on long-term AGN
variability, to provide interesting clues to detect probable hidden TDEs in normal broad line …

The black hole of an active galactic nucleus is encircled by an accretion disk. The surface
density of the disk is always too low to affect the tidal disruption of a star, but it can be high …
