Stars that interact with supermassive black holes (SMBHs) can be either completely or
partially destroyed by tides. In a partial tidal disruption event (TDE), the high-density core of …

Quasi-periodic eruptions (QPEs) are luminous bursts of soft X-rays from the nuclei of
galaxies, repeating on timescales of hours to weeks,,,–. The mechanism behind these rare …

Most, if not all, galaxies harbor at their center a supermassive black hole (SMBH) that sculpts
the dynamics of objects inhabiting galactic nuclei. SMBH binaries (SMBHBs) are expected to …

We present a toy model for the thermal optical/UV/X-ray emission from tidal disruption
events (TDEs). Motivated by recent hydrodynamical simulations, we assume that the debris …

Late-time (∼ a year) radio follow-up of optically discovered tidal disruption events (TDEs) is
increasingly resulting in detections at radio wavelengths, and there is growing evidence for …

Stars falling too close to massive black holes in the centers of galaxies can be torn apart by
the strong tidal forces. Simulating the subsequent feeding of the black hole with disrupted …

We present six epochs of optical spectropolarimetry of the Type IIP supernova (SN) 2021yja
ranging from∼ 25 to 95 d after the explosion. An unusually high continuum linear …

Mrk 501 is a prototypical high-synchrotron-peaked blazar and serves as one of the primary
targets for the Imaging X-ray Polarimetry Explorer (IXPE). In this study, we report X-ray …

Tidal disruption events occur when a star is disrupted by a supermassive black hole,
resulting in an elongated stream of gas that partly falls back to the pericentre. Due to apsidal …

Three tidal disruption event (TDE) candidates (AT2019dsg, AT2019fdr, AT2019aalc) have
been found to be coincident with high-energy astrophysical neutrinos in multimessenger …
