1 day ago · Sagittarius A*, abbreviated Sgr A* ( / ˈsædʒ ˈeɪ stɑːr / SADGE-AY-star [3] ), is the supermassive black hole [4] [5] [6] at the Galactic Center of the Milky Way. Viewed from Earth, it is located near the border of the constellations Sagittarius and Scorpius, about 5.6° south of the ecliptic, [7] visually close to the Butterfly Cluster ...
1 day ago · These black holes are between 100 and 1,000 times as massive as Sagittarius A* (Sgr A*), the supermassive black hole at the heart of the Milky Way that sits just 26,000 light-years from Earth.
1 day ago · Black hole theory, dating back to the 1970s, shows that thermal pressure is a dominant force in supermassive black hole accretion disks. These theories show that thermal pressure prevents the ...
4 days ago · July 02, 2024. A team of astrophysicists led by Caltech has managed for the first time to simulate the journey of primordial gas dating from the early universe to the stage at which it becomes swept up in a disk of material fueling a single supermassive black hole. The new computer simulation upends ideas about such disks that astronomers have ...
2 days ago · Astrophysicists have discovered an unusual outburst phase of a black hole binary source Swift J1727.8-1613 1. It emitted X-rays with quasi-periodic oscillations (QPOs) while sucking in matter from ...
2 days ago · Supermassive black holes are ravenous. Clumps of dust and gas are prone to being disrupted by the turbulence and radiation when they are pulled too close. So why are some of them orbiting on the ...
1 day ago · News. Super-massive black holes quickly repoint their jets. 5 July 2024. Into the void Two galaxy clusters observed by the Chandra X-ray Observatory, showing the cavities (green ellipses), the current direction of the radio jets (white line), and the location of their parent super-massive black hole (red cross).
