Rubin Observatory’s Survey Strategy Performance for Tidal Disruption Events
The Astrophysical Journal Supplement Series, 2023 Tidal disruption events (TDEs) are rare transients, which are considered as promising tools for probing supermassive black holes in quiescent galaxies.

Stellar dynamics and tidal disruption events in galactic nuclei
EPJ Web of Conferences, 2012 The disruption of a star by the tidal field of a massive black hole is the final outcome of a chain of complex dynamical processes in the host galaxy. I introduce the “loss cone problem”, and describe the many theoretical and numerical challenges on the ...

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

Ultraviolet and optical observations of tidal disruption events
EPJ Web of Conferences, 2012 Tidal disruption events are expected to produce a luminous flare of radiation from fallback accretion of tidally disrupted stellar debris onto the central supermassive black hole.

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

Propagation of a Precessing Jet in the Envelope of Tidal Disruption Events
The Astrophysical JournalIt 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 ...

The 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

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

Reverberation Evidence for Stream Collision and Delayed Disk Formation in Tidal Disruption Events
The Astrophysical JournalWhen 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
The Astrophysical JournalThe 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.
