Tidal disruption events (TDEs) offer a unique way to study dormant black holes. While the
number of observed TDEs has grown thanks to the emergence of wide-field surveys in the …

We present the first sample of tidal disruption events (TDEs) discovered during the SRG all-
sky survey. These 13 events were selected among X-ray transients detected in the 0°< l< …

This is the first in a collection of three papers introducing the science with an ultra-violet (UV)
space telescope on an approximately 130 kg small satellite with a moderately fast re …

In recent years, searches of archival X-ray data have revealed galaxies exhibiting nuclear
quasi-periodic eruptions with periods of several hours. These are reminiscent of the tidal …

There is growing observational evidence for dwarf galaxies hosting active galactic nuclei
(AGN), including hints of AGN-driven outflows in dwarfs. However, in the common theoretical …

We review the properties of the established Scaling Relations (SRs) of galaxies and active
galactic nuclei (AGN), focusing on their origin and expected evolution back in time, providing …

We conduct a systematic tidal disruption event (TDE) demographics analysis using the
largest sample of optically selected TDEs. A flux-limited, spectroscopically complete sample …

Massive black holes (BHs) at the centres of massive galaxies are ubiquitous. The population
of BHs within dwarf galaxies, on the other hand, is not yet known. Dwarf galaxies are thought …

Tidal disruption events (TDEs) occur when a star gets torn apart by a supermassive black
hole as it crosses its tidal radius. We present late-time optical and X-ray observations of the …

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 …
