If scientists are right, they'll have some theories to update.
, named Leo I*, was first proposed to exist in 2021, when astronomers noticed stars accelerating as they approached the heart of the dwarf galaxy. While this is good evidence in favor of a supermassive black hole, astronomers frustratingly couldn't get a direct image of emissions from Leo I* to prove it exists. Now, two researchers have proposed a solution.
"Black holes are very elusive objects, and sometimes they enjoy playing hide-and-seek with us," Fabio Pacucci, an astrophysicist at the Harvard & Smithsonian Center for Astrophysics and lead author of the research, said in a."Rays of light cannot escape their event horizons, but the environment around them can be extremely bright — if enough material falls into their gravitational well.
If the technique works, the observation of Leo I* could be groundbreaking, according to Avi Loeb, an astrophysicist also at the Harvard & Smithsonian Center for Astrophysics. In particular, a detection would resolve another astronomical mystery: whether dwarf galaxies possess supermassive black holes of these tremendous masses at all.
"It would be the second-closest supermassive black hole after the one at the center of our galaxy, with a very similar mass but hosted by a galaxy that is a thousand times less massive than the Milky Way," Loeb said in the statement."This fact challenges everything we know about how galaxies and their central supermassive black holes co-evolve.
