A well-monitored, X-ray selected, tidal disruption event

EPJ Web of Conferences, 2012
We report on a candidate tidal disruption event detected in the XMM-Newton slew survey from the nucleus of SDSS J120136.02+300305.5 (z = 0.146; hereafter SDSS J1201+30).

Extended Emission-line Regions in Poststarburst Galaxies Hosting Tidal Disruption Events

The Astrophysical Journal Letters
We report the discovery of an extended emission-line region (EELR) in MUSE observations of Markarian 950, a nearby ( z = 0.01628) poststarburst (PSB) galaxy that hosted the tidal disruption event (TDE) iPTF 16fnl.

Prompt emission from tidal disruptions of white dwarfs by intermediate mass black holes

EPJ Web of Conferences, 2012
We present a qualitative picture of prompt emission from tidal disruptions of white dwarfs (WD) by intermediate mass black holes (IMBH). The smaller size of an IMBH compared to a supermassive black hole and a smaller tidal radius of a WD disruption lead ...

Tidal Disruption Events through the Lens of the Cooling Envelope Model

The Astrophysical Journal Letters
The cooling envelope model for tidal disruption events (TDEs) postulates that while the stellar debris streams rapidly dissipate their bulk kinetic energy (“circularize”), this does not necessarily imply rapid feeding of the supermassive black hole (SMBH)

Early identification of optical tidal disruption events

Astronomy & Astrophysics
Context. The detection of tidal disruption events (TDEs) is one of the key science goals of large optical time-domain surveys such as the Zwicky Transient Facility (ZTF) and the upcoming Vera C.

A New Population of Mid-infrared-selected Tidal Disruption Events: Implications for Tidal Disruption Event Rates and Host Galaxy Properties

The Astrophysical Journal
Most tidal disruption events (TDEs) are currently found in time-domain optical and soft X-ray surveys, both of which are prone to significant obscuration. The infrared (IR), however, is a powerful probe of dust-enshrouded environments; hence, we recently

Optical Appearance of Eccentric Tidal Disruption Events

The Astrophysical Journal Letters
Stars approaching supermassive black holes can be tidally disrupted. Despite being expected to emit X-rays, tidal disruption events (TDEs) have been largely observed in optical bands, which is poorly understood.

Repeating partial disruptions and two-body relaxation

The Open Journal of Astrophysics
Two-body relaxation may drive stars onto near-radial orbits around a massive black hole, resulting in a tidal disruption event (TDE). In some circumstances, stars are unlikely to undergo a single terminal disruption, but rather to have a sequence of many
