Tidal disruption events (TDEs) are bursts of electromagnetic energy that are released when
supermassive black holes at the centres of galaxies violently disrupt a star that passes too …

A tidal disruption event (TDE) ensues when a star passes too close to a supermassive black
hole (SMBH) in a galactic center, and is ripped apart by its tidal field. The gaseous debris …

After a star has been tidally disrupted by a black hole, the debris forms an elongated stream.
We start by studying the evolution of this gas before its bound part returns to the original …

Context. GSN 069 is the first galactic nucleus where quasi-periodic eruptions (QPEs) have
been identified in December 2018. These are high-amplitude, soft X-ray bursts recurring …

While once rare, observations of stars being tidally disrupted by supermassive black holes
are quickly becoming commonplace. To continue to learn from these events, it is necessary …

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 …

We propose a semi-analytical model for the self-intersection of the fallback stream in tidal
disruption events (TDEs). When the initial periapsis is less than about 15 gravitational radii …

Context. Quasi-periodic eruptions (QPEs) are repeating thermal X-ray bursts associated with
accreting massive black holes, the precise underlying physical mechanisms of which are still …

When a star passes within the tidal radius of a supermassive black hole, it will be torn
apart1. For a star with the mass of the Sun (M⊙) and a non-spinning black hole with a …

We present observations of PS16dtm (also known as SN 2016ezh), a luminous transient that
occurred at the nucleus of a narrow-line Seyfert 1 galaxy hosting a 10 6 M⊙ black hole. The …
