Astronomers discovered light jetting out from a tidal disruption event, where a supermassive black hole swallowed a star. The beam of visible light is heading towards the Earth.
"The event started when an ill-fated star approached the supermassive black hole on a nearly parabolic trajectory and was ripped apart into a stream of gaseous debris," read the scientific paper, published on Nov. 30."About half of the mass stayed bound to the black hole, underwent general-relativistic apsidal precession as the gas fell back towards the pericenter, and then produced strong shocks at the self-crossing point.
The TDE was discovered in Feb. 2022, before the scientific news journal received the paper about it in April 2022, and the research was finally accepted in October 2022.The Herschel Space Observatory has shown that galaxies with the most powerful, active, supermassive black holes at their cores produce fewer stars than galaxies with less active black holes.
"This discovery has created widespread excitement because we can use tidal disruption events not only to find more intermediate-mass The discovery spanned years of research as the distant galaxy was first observed in June 2020, and was confirmed with Young Supernova Experiment data. It was observed again from July 1, 2020, to July 17, 2020; then from August 5, 2020, to September 6, 2020.
