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 …

Radio observations of tidal disruption events (TDEs) probe material ejected by the disruption
of stars by supermassive black holes (SMBHs), uniquely tracing the formation and evolution …

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 …

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 …

A black hole can launch a powerful relativistic jet after it tidally disrupts a star. If this jet
fortuitously aligns with our line of sight, the overall brightness is Doppler boosted by several …

Context. During its all-sky survey, the extended ROentgen Survey with an Imaging
Telescope Array (eROSITA) on board the Spectrum-Roentgen-Gamma (SRG) observatory …

Wide-field optical surveys have begun to uncover large samples of fast (t rise≲ 5 d),
luminous (M peak<− 18), blue transients. While commonly attributed to the breakout of a …

We present the results of a Palomar Transient Factory (PTF) archival search for blue
transients that lie in the magnitude range between" normal" core-collapse and …

Rates of stellar tidal disruption events (TDEs) by supermassive black holes (SMBHs) due to
two-body relaxation are calculated using a large galaxy sample (N≈ 200) in order to …

THESEUS is a space mission concept aimed at exploiting Gamma-Ray Bursts for
investigating the early Universe and at providing a substantial advancement of multi …
