Tidal disruption events

S Gezari - Annual Review of Astronomy and Astrophysics, 2021 - annualreviews.org
The concept of stars being tidally ripped apart and consumed by a massive black hole
(MBH) lurking in the center of a galaxy first captivated theorists in the late 1970s. The …

Intermediate-mass black holes

JE Greene, J Strader, LC Ho - Annual Review of Astronomy and …, 2020 - annualreviews.org

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 …

Observational evidence for intermediate-mass black holes

M Mezcua - International Journal of Modern Physics D, 2017 - World Scientific
Intermediate-mass black holes (IMBHs), with masses in the range 1 0 0–1 0 6 M⊙, are the
link between stellar-mass BHs and supermassive BHs (SMBHs). They are thought to be the …
