A large number of tidal disruption event (TDE) candidates have been observed recently, often differing in their observational features. Two classes appear to stand out: X-ray and optical TDEs, the latter featuring lower effective temperatures and luminosities. These differences can be explained if the radiation detected from the two categories of events originates from different locations. In practice, this location is set by the evolution of the debris stream around the black hole and by the… Expand

Self-intersection of the fallback stream in tidal disruption events
• Physics
• 2019
We propose a semi-analytical model for the self-intersection of the fallback stream in tidal disruption events (TDEs). When the blackhole mass exceeds a critical value M_cr, a large fraction of theExpand
Stellar tidal disruption events in general relativity
• Physics
• General Relativity and Gravitation
• 2019
A tidal disruption event (TDE) ensues when a star passes too close to a supermassive black hole (SMBH) in a galactic center, and is ripped apart by its tidal field. The gaseous debris produced in aExpand
Revisiting Optical Tidal Disruption Events with iPTF16axa
We report the discovery by the intermediate Palomar Transient Factory (iPTF) of a candidate tidal disruption event (TDE) iPTF16axa at z = 0.108 and present its broadband photometric and spectroscopicExpand
Simulating disc formation in tidal disruption events
• Physics
• 2019
A star coming too close to a supermassive black hole gets disrupted by the tidal force of the compact object in a tidal disruption event, or TDE. Following this encounter, the debris evolves into anExpand
Magnetic field evolution in tidal disruption events
• Physics
• 2017
When a star gets tidally disrupted by a supermassive black hole, its magnetic field is expected to pervade its debris. In this paper, we study this process via smoothed particle magnetohydrodynamicalExpand
X-Ray Properties of TDEs
• Physics

Observational astronomy of tidal disruption events (TDEs) began with the detection of X-ray flares from quiescent galaxies during the ROSAT all-sky survey of 1990–1991. The flares complied withExpand
X-Ray Brightening and UV Fading of Tidal Disruption Event ASASSN-15oi
• Physics

We present late-time observations by Swift and XMM-Newton of the tidal disruption event (TDE) ASASSN-15oi that reveal that the source brightened in the X-rays by a factor of $\sim10$ one year afterExpand
Tidal Disruption of a Main-sequence Star by an Intermediate-mass Black Hole: A Bright Decade
• Physics
• 2018
There has been suggestive evidence of intermediate-mass black holes (IMBHs; 10^{3-5} M_sun) existing in some globular clusters (GCs) and dwarf galaxies, but IMBHs as a population remain elusive. As aExpand
Optical follow-up of the tidal disruption event iPTF16fnl: new insights from X-shooter observations

• 2019
We present the results from Nordic Optical Telescope and X-shooter follow-up campaigns of the tidal disruption event (TDE) iPTF16fnl, covering the first ∼100 d after the transient discovery. WeExpand
What Sets the Line Profiles in Tidal Disruption Events
