A comma-shaped molecular cloud near the center of the Milky Way seems to be orbiting one of the most sought-after objects in astronomy.
At the center of the"Tadpole's" orbit, a team of astronomers saw precisely … nothing. And a nothing which attracts something simply screams 'Modeling suggests that this wouldn't just be any run-of-the-mill black hole either, but one belonging to the rarely-seen class of middleweights; the"missing link" intermediate-massIf this is the case, it would be the fifth candidate intermediate black hole found near the galactic center.
This growing number of heretofore elusive objects could help astronomers figure out how the supermassive black holes at the centers of galaxies form, and then grow to such colossal size.write a team of astronomers"The spatial compactness of the Tadpole and absence of bright counterparts in other wavelengths indicate that the object could be an intermediate-mass black hole."
Black holes in the Universe tend to be found in two distinct mass regimes. There are the stellar-mass black holes, up to around 100 times the mass of the Sun. These are black holes that form from the core collapse of a massive star at the end of its life, orThen there are the supermassive black holes. These are the giant chonkers that sit in the centers of galaxies, with masses millions to billions of times that of the Sun.
It's unclear how these objects form, and that's a cosmic conundrum that astronomers would love to resolve. One place answers might be found is among black holes with in-between masses. Finding these intermediate-mass black holes would be evidence that black holes evenly span an entire range of masses, and that the intermediate ones are a stage of growth between titch and behemoth.for the most part only tentativelyOne of the problems is that lone black holes don't emit any light on their own.
