KnowraSagittarius A*Linked fromLinked fromThe 20 pages that link to Sagittarius A*, each with the reason it gives.All 20Broader topic 13Related 6Compared with 1Milky WayBroader topic: Its stellar orbits provide direct evidence for a roughly four-million-solar-mass black hole in the Galactic center.Black holeBroader topic: Stellar orbits around it provide direct evidence for a massive central object.Supermassive black holeBroader topic: Stellar orbits around it provide direct evidence for a supermassive black hole in our own galaxy.Event Horizon TelescopeBroader topic: The EHT produced the first image of its black-hole shadow in 2022.Chandra X-ray ObservatoryBroader topic: Chandra observations track X-ray flares and hot gas near the black hole.Galactic CenterBroader topic: It is the Galactic Center’s dominant compact object and anchors the surrounding stellar orbits.Sagittarius Dwarf Spheroidal GalaxyCompared with: Its similar name can cause confusion, but it is the Milky Way’s central source, not this satellite galaxy.Bow shockRelated: The bow shock of the star S2 near Sagittarius A* has been proposed as a source of observable radiation.Very Long Baseline ArrayBroader topic: VLBA observations help measure its radio structure and the motions of nearby sources.Solar massBroader topic: Its mass illustrates how the same unit scales from stars to galactic centers.Nuclear star clusterRelated: It lies at the center of the Milky Way nuclear star cluster.Reinhard GenzelRelated: The object whose mass Genzel’s team inferred from nearby stars’ orbits.W. M. Keck ObservatoryBroader topic: Keck’s long-term measurements of nearby stars helped establish its mass and location.Sagittarius B2Related: It is a prominent Galactic-center landmark near Sagittarius B2, but is a distinct object.Electromagnetic astronomyRelated: Observations at radio, infrared, and X-ray wavelengths probe its surroundings and activity.Galactic astronomyBroader topic: Its mass and activity inform studies of the central Galaxy, though its growth history remains unresolved.Robert BrownRelated: Brown and Bruce Balick identified this compact radio source in 1974.Andrea M. GhezBroader topic: Stars tracked by Ghez orbit this source, whose mass and compactness identify it as a black hole.Astronomical black holesBroader topic: Stellar orbits around it provide strong evidence for a central black hole in our galaxy.Black hole astronomyBroader topic: Its stars and radio emission provide unusually close evidence of a galactic-center black hole.
