  • The tidal disruption event AT2019dsg is probably associated with a high-energy neutrino, suggesting that such events can contribute to the cosmic neutrino flux. The electromagnetic emission is explained in terms of a central engine, a photosphere and an extended synchrotron-emitting outflow.

  • Multiwavelength observations of a galactic nucleus exhibit quasi-periodic X-ray eruptions (QPEs) that repeat every 22 days, a timescale intermediate between those of other QPEs and so-called repeating nuclear transients. The eruptions are likely to be driven by the interaction between an orbiting body and a central massive black hole.
