Scientists confirm an 8,200-solar-mass black hole in the Omega Centauri cluster using 20 years of Hubble data, shedding light on black hole formation and evolution.
Omega Centauri (ω Cen, NGC 5139, or Caldwell 80) is a globular cluster in the constellation of Centaurus that was first identified as a non-stellar object by Edmond Halley in 1677. Located at a distance of 17,090 light-years (5,240 parsecs ), it is the largest known globular cluster in the Milky Way at a diameter of roughly 150 light-years. [ 10 ]
“We now have an answer to that and the confirmation that Omega Centauri contains an intermediate-mass black hole. “At a distance of about 18,000 light-years, this is the closest known example ...
Mayall II is considered to have twice the mass of Omega Centauri, and may contain a central, intermediate-mass (~ 2 × 10 4 M ⊙) black hole. [3] It was first identified as a possible globular cluster by American astronomers Nicholas Mayall and Olin J. Eggen in 1953 using a Palomar 48-inch (1.2 m) Schmidt plate exposed in 1948. [3]
Globular cluster Mayall II (M31 G1) is a possible candidate for hosting an intermediate-mass black hole at its center [1]. An intermediate-mass black hole (IMBH) is a class of black hole with mass in the range of one hundred to one hundred thousand (10 2 –10 5) solar masses: significantly higher than stellar black holes but lower than the hundred thousand to more than one billion (10 5 –10 ...
Fimbulthul is a tidal stellar stream torn off from Omega Centauri, the largest globular cluster of our Milky Way galaxy. The stream contains 309 known stars stretching over 18° in the constellations of Hydra and Centaurus , matching the same age as the globular cluster.
This is a list of known black holes that are close to the Solar System. It is thought that most black holes are solitary, but black holes in binary or larger systems are much easier to detect. [1] Solitary black holes can generally only be detected by measuring their gravitational distortion of the light from more
The supermassive black hole at the core of Messier 87, here shown by an image by the Event Horizon Telescope, is among the black holes in this list.. This is an ordered list of the most massive black holes so far discovered (and probable candidates), measured in units of solar masses (M ☉), approximately 2 × 10 30 kilograms.
