NGC 4526 is a lenticular galaxy in the Virgo constellation that is seen nearly edge-on. The morphological classification is SAB(s)0°,[4] which indicates a lenticular structure with a weak bar across the center and pure spiral arms without a ring.[5] It belongs to the Virgo cluster and is one of the brightest known lenticular galaxies.[4] The inner nucleus of this galaxy displays a rise in stellar orbital motion that indicates the presence of a central dark mass. The best fit model for the motion of molecular gas in the core region suggests there is a supermassive black hole with about 4.5+4.2
−3.0×108 (450 million) times the mass of the Sun.[6] This is the first object to have its black-hole mass estimated by measuring the rotation of gas molecules around its centre with an Astronomical interferometer (in this case the Combined Array for Research in Millimeter-wave Astronomy).
Supernova SN 1969E was discovered in this galaxy in 1969, reaching a peak magnitude of 16.[7] In 1994, a Type 1a supernova was discovered about two weeks before reaching peak brightness. Designated SN 1994D, it was caused by the explosion of a white dwarf star composed of carbon and oxygen.[8]
