The power of quasars originates from supermassive black holes that are believed to exist at the core of most galaxies. The Doppler shifts of stars near the cores of galaxies indicate that they are revolving around tremendous masses with very steep gravity gradients, suggesting black holes.
First quasar found to seemingly not have a host galaxy HE0450-2958 (Naked Quasar) 2005 Some disputed observations suggest a host galaxy, others do not. First multi-core quasar PG 1302-102: 2014 Binary supermassive black holes within the quasar [37] [38] First quasar containing a recoiling supermassive black hole SDSS J0927+2943: 2008
OJ 287 core black holes — a BL Lac object with a candidate binary supermassive black hole core system [23] PG 1302-102 – the first binary-cored quasar — a pair of supermassive black holes at the core of this quasar [24] [25] SDSS J120136.02+300305.5 core black holes — a pair of supermassive black holes at the centre of this galaxy [26]
The cosmic scale of time is long, and supermassive black holes can be thousands of light years across. Quasars, though, are on the small end of the supermassive black hole size class—sometimes ...
The 1997 science-fiction film Men In Black, starring Will Smith and Tommy Lee Jones, was loosely based on The Men in Black comic book series created by Lowell Cunningham and Sandy Carruthers. [11] Cunningham got the idea for the comic when he and a friend saw a black van on the street and his friend joked about government "men in black". [12]
3C 279 (also known as 4C–05.55, NRAO 413, and PKS 1253–05) is an optically violent variable quasar (OVV), which is known in the astronomical community for its variations in the visible, radio and X-ray bands. [2] The quasar was observed to have undergone a period of extreme activity from 1987 until 1991. [3]
APM 08279+5255 is a very distant, broad absorption line quasar located in the constellation Lynx. It is magnified and split into multiple images by the gravitational lensing effect of a foreground galaxy through which its light passes. It appears to be a giant elliptical galaxy with a supermassive black hole and associated accretion disk.
3C 273 is a quasar located at the center of a giant elliptical galaxy in the constellation of Virgo. It was the first quasar ever to be identified and is the visually brightest quasar in the sky as seen from Earth, with an apparent visual magnitude of 12.9. [2] The derived distance to this object is 749 megaparsecs (2.4 billion light-years).
