Black Holes

Astronomers have uncovered evidence that a black hole and neutron star merged while following an unusual oval-shaped orbit, challenging expectations of circular paths in such events. The discovery comes from a reanalysis of gravitational wave data from the event known as GW200105. This finding suggests the system formed in a dynamic stellar environment.

Astronomers have detected a mysterious cosmic explosion known as AT 2024wpp, or the Whippet, which is the brightest fast blue optical transient observed to date. Researchers suggest it resulted from a massive Wolf-Rayet star being devoured by a black hole. The event, spotted at the end of 2024, offers new insights into rare stellar phenomena.

An international team has discovered a quasar in the early universe hosting a supermassive black hole that grows at an extraordinary rate. Observations reveal it accreting matter 13 times faster than the theoretical limit while emitting strong X-rays and a radio jet. This unusual behavior challenges existing models of black hole development.

Astronomers have observed a supermassive black hole in the galaxy VV 340a launching a wobbling jet that expels star-forming gas at a rate of about 19 solar masses per year. This process, captured using multiple telescopes including the James Webb Space Telescope, demonstrates how black holes can regulate galaxy evolution by limiting new star formation. The jet's precession, resembling a spinning top, enhances its interaction with surrounding gas.
