Core Insights - Astronomers have discovered a black hole with a mass approximately 36.3 billion times that of the Sun, potentially the largest black hole detected to date [1][3] Group 1: Discovery and Measurement - The black hole is located in the "Cosmic Horseshoe" galaxy, which is one of the most massive known galaxies [1] - The research team, led by Professor Thomas Collett from the University of Portsmouth, measured the speed of stars orbiting the black hole and the degree of light bending caused by its gravity to confirm its existence [3] - The black hole's mass was determined through a combination of these measurements, with stars moving at speeds nearly reaching 400 kilometers per second [3] Group 2: Implications and Context - The discovery aligns with previous research indicating that a supermassive black hole must exist at the center of the "Cosmic Horseshoe" for the model of dark matter distribution to match observational data [3] - This black hole is categorized as a "sleeping" black hole, meaning it is not actively accreting material, and its detection relies solely on its immense gravitational influence [3][4] - The findings provide new insights into the relationship between supermassive black holes and their host galaxies, suggesting that the black hole may have formed from the merger of supermassive black holes from satellite galaxies [4]
