Tidal Disruption of Milky Way Satellites with Shallow Dark Matter Density Profiles

open access: yesGalaxies, 2016
Dwarf galaxies of the Local Group provide unique possibilities to test current theories of structure formation. Their number and properties have put the broadly accepted cold dark matter model into question, posing a few problems. These problems now seem

Propagation of a Precessing Jet in the Envelope of Tidal Disruption Events

open access: yesThe Astrophysical Journal
It is likely that the disk of a tidal disruption event (TDE) is misaligned with respect to the equatorial plane of the spinning supermassive black hole (SMBH), since the initial stellar orbit before disruption most likely has an inclined orbital plane ...

AT2022cmc: A Tidal Disruption Event with a Two-component Jet in a Bondi-profile Circumnuclear Medium

open access: yesThe Astrophysical Journal
A supermassive black hole can launch a relativistic jet when it violently disrupts a star that passes too close. Such jetted tidal disruption events (TDEs) are rare and unique tools to investigate quiescent supermassive black holes, jet physics, and ...

AT 2022aedm and a New Class of Luminous, Fast-cooling Transients in Elliptical Galaxies

open access: yesThe Astrophysical Journal Letters, 2023
We present the discovery and extensive follow-up of a remarkable fast-evolving optical transient, AT 2022aedm, detected by the Asteroid Terrestrial impact Last Alert Survey (ATLAS).

Reverberation Evidence for Stream Collision and Delayed Disk Formation in Tidal Disruption Events

open access: yesThe Astrophysical Journal
When a star passes through the tidal disruption radius of a massive black hole (BH), it can be torn apart by the tidal force of the BH, known as the tidal disruption event (TDE).

Fallback Rates in Partial Tidal Disruptions of White Dwarfs by Intermediate-mass Black Holes

open access: yesThe Astrophysical Journal
The fallback rate of debris after the partial tidal disruption of a star by an intermediate-mass black hole (IMBH) might provide important signatures of such black holes rather than supermassive ones.

Mid-infrared Outbursts in Nearby Galaxies: Nuclear Obscuration and Connections to Hidden Tidal Disruption Events and Changing-look Active Galactic Nuclei

open access: yesThe Astrophysical Journal Letters, 2023
We study the properties of galaxies hosting mid-infrared outbursts in the context of a catalog of 500,000 galaxies from the Sloan Digital Sky Survey. We find that nuclear obscuration, as inferred by the surrounding dust mass, does not correlate with host

A Unified Model for Tidal Disruption Events [PDF]

open access: yesThe Astrophysical Journal Letters, 2018
Abstract In the past few years wide-field optical and UV transient surveys and X-ray telescopes have allowed us to identify a few dozen candidate tidal disruption events (TDEs). While in theory the physical processes in TDEs are ubiquitous, a few distinct classes of TDEs have been observed.
