The gravitational wave detectors have shown a population of massive black holes that do not resemble those observed in the Milky Way1,2,3 and whose origin is debated4,5,6. According to a possible explanation, these black holes may have formed from density fluctuations in the early Universe (...
Astronomers found the most massive stellar-mass black hole in the galaxy after spotting a star "wobbling" nearby. The baby monster is the 2nd-closest black hole to Earth ever detected.
We derive the black hole occupation fraction (BHOF) of the satellite population at z= 0. MBHs generated as massive seeds have large masses that would favour their identification, but their typical BHOF is always below 40 per cent and decreases to 1 per cent for observed dwarf galaxy sizes....
and it can also affect the structure of the galaxy it resides in. For example, the supermassive black hole at the center of the Milky Way is believed to play a role in the formation and evolution of the galaxy
Full Three Dimensional Orbits For Multiple Stars on Close Approaches to the Central Supermassive Black Hole taken in building the case for a supermassive black hole at the center of the Milky Way and understanding the black hole's effect on its environment. ... AM Ghez,E Becklin,G Duchêne,...
These dwarf galaxies, more than 100 times less massive than our ownMilky Way, are among the smallest galaxies known to host massive black holes. The scientists expect that the black holes in these smaller galaxies average about 400,000 times the mass of our Sun. ...
astronomers in the UNC-Chapel Hill Department of Physics & Astronomy has found a previously overlooked treasure trove of massive black holes in dwarf galaxies. The newly discovered black holes offer a glimpse into the life story of the supermassive black hole at the center of our ownMilky Way...
B. A massive supernova will be formed and then exploded if the sun in our galaxy dies. C. “The Milky Way” was formed after a supermassive black hole collapsed and exploded. D. If “the Milky Way” dies, a supermassive black hole will be formed after its death. 相关知识点: 试题来...
(40 billion times the mass of the sun), this behemoth dwarves the milky way's central black hole, sagittarius a*— a puny 4 million solar masses . in fact, it dwarves every other black hole in our galaxy's vicinity. "[the black hole] is the most massive with a direct and accurate...
Astronomers may have discovered a massive black hole that is about 68 times larger than the sun. Current physics models don't support the existence of a black hole this size in the Milky Way galaxy, so the discovery is raising many questions. Several scientists have come forward and published...
