This central engine is believed to be a black hole.<\/p>\n<p>If true, this would be a phenomenon that \u201chas never been observed before,\u201d according to de Graaff.<\/p>\n<p>Some scientists have compared them to Quasi-stars, theoretical objects powered by a black hole, which are luminous due to the cloud of gas that surrounds them.<\/p>\n<p>Pierluigi Rinaldi, a postdoctoral research fellow at the Space Telescope Science Institute (STSci), told the <a href=\"https:\/\/www.skyatnightmagazine.com\/news\/virgil-galaxy-little-red-dots-black-hole\" target=\"_blank\" rel=\"noopener nofollow\">BBC\u2019s Sky At Night<\/a> magazine that in this scenario, the \u201clittle red dots are envisioned as black holes embedded within extremely dense cocoons of gas.\u201d<\/p>\n<p>\u201cRadiation produced near the black hole can become trapped inside this envelope, scattering many times before escaping,\u201d he said. \u201cThis idea remains speculative, but if correct, it would significantly change how we think black holes grew in the early Universe.\u201d<\/p>\n<p>Mitch Begelman, an astrophysicist at the University of Colorado Boulder who predicted the quasi-star phenomenon, believes they don\u2019t have a \u201csmoking gun\u201d but doesn\u2019t see a problem with this explanation for little red dots.<\/p>\n<p>However, others have urged caution about being so quick to label these dots quasi-stars, as it would suggest they were some star-black hole hybrid.<\/p>\n<p>\u201cIt could well be that LRDs are quasi-stars, but in my view, we have not yet fully ruled out other scenarios,\u201d Matthee said. \u201cI would definitely love this to be true, as it would imply we discovered a new type of astrophysical phenomena that bridges stars and supermassive black holes, but it\u2019s too early to tell, in my view.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"They\u2019re struggling to connect the dots.
