  • A millihertz frequency X-ray quasi-periodic oscillation has been observed near the innermost orbit of an actively accreting supermassive black hole and its frequency has evolved significantly over 2 years, a phenomenon that is difficult to explain with existing models.

  • X-ray quasi-periodic eruptions are detected from two previously inactive galaxies, with observations suggesting that the very-high-amplitude X-ray bursts may arise from an orbiting compact object.

  • 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.

  • Observations from a multiwavelength campaign of a low-mass X-ray binary, Swift J1858.6–0814, shows that accreting neutron stars have the same kind of pulsing behaviour as accreting black holes.
