Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

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 …

While tidal disruption events (TDEs) have long been heralded as laboratories for the study of
quiescent black holes, the small number of known TDEs and uncertainties in their emission …

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< …

The quest for binary and dual supermassive black holes (SMBHs) at the dawn of the multi-
messenger era is compelling. Detecting dual active galactic nuclei (AGN)–active SMBHs at …

Roughly half of the quasiperiodic eruption (QPE) sources in galactic nuclei exhibit a
remarkably regular alternating" long-short" pattern of recurrence times between consecutive …

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

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 …

We present optical spectroscopic and Swift UVOT/XRT observations of the X-ray and
UV/optical bright tidal disruption event (TDE) candidate AT 2018fyk/ASASSN–18ul …

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 …
