Optical-ultraviolet tidal disruption events

S van Velzen, TWS Holoien, F Onori, T Hung… - Space science …, 2020 - Springer
The existence of optical-ultraviolet Tidal Disruption Events (TDEs) could be considered
surprising because their electromagnetic output was originally predicted to be dominated by …

Distinguishing tidal disruption events from impostors

A Zabludoff, I Arcavi, S La Massa, HB Perets… - Space Science …, 2021 - Springer
Recent claimed detections of tidal disruption events (TDEs) in multi-wavelength data have

An embedded X-ray source shines through the aspherical AT 2018cow: revealing the inner workings of the most luminous fast-evolving optical transients

R Margutti, BD Metzger, R Chornock… - The Astrophysical …, 2019 - iopscience.iop.org
We present the first extensive radio to γ-ray observations of a fast-rising blue optical

Weighing black holes using tidal disruption events

B Mockler, J Guillochon… - The Astrophysical …, 2019 - iopscience.iop.org

New physical insights about tidal disruption events from a comprehensive observational inventory at X-ray wavelengths

K Auchettl, J Guillochon… - The Astrophysical …, 2017 - iopscience.iop.org
We perform a comprehensive study of the X-ray emission from 70 transient sources that

Self-intersection of the fallback stream in tidal disruption events

W Lu, C Bonnerot - Monthly Notices of the Royal Astronomical …, 2020 - academic.oup.com
We propose a semi-analytical model for the self-intersection of the fallback stream in tidal

On the mass and luminosity functions of tidal disruption flares: rate suppression due to black hole event horizons

S van Velzen - The Astrophysical Journal, 2018 - iopscience.iop.org
The tidal disruption of a star by a massive black hole is expected to yield a luminous flare of
thermal emission. About two dozen of these stellar tidal disruption flares (TDFs) may have …
