1 giorno fa · The British astronomer Carole Mundell, 54, has a resume that reads like a movie: an expert in supermassive black holes, a scientific advisor to the British government, president of the UK Science Council and, now, Director of Science at the European Space Agency (ESA). This year alone, the ...
4 giorni fa · A black hole is a region of spacetime where gravity is so strong that nothing, including light and other electromagnetic waves, is capable of possessing enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
2 giorni fa · Comparisons of large and small black holes in galaxy OJ 287 to the Solar System. A supermassive black hole (SMBH) is an extremely large black hole, on the order of hundreds of thousands to billions of solar masses (M ☉), and is theorized to exist in the center of almost all massive galaxies.
15 mag 2024 · Studying theoretical, fast-spinning black holes is helping physicists understand more about the elusive black holes out in the universe.
1 giorno fa · Black holes threaded by massive vector fields can be subject to a superradiant instability, growing a cloud of massive vector particles around it. In this work, we consider what happens if such a dark matter candidate field mimicking a dark photon interacts with an accretion flow onto the black hole. By including a kinetic mixing term with the standard model photon, we extend the commonly used ...
