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
The oldest visible quasar is over 13 billion years old, which means it needed to already be a supermassive black hole when the universe was very, very young—at least, according to our current ...
In popular culture and UFO conspiracy theories, men in black (MIB) are government agents dressed in black suits, who question, interrogate, harass, threaten, allegedly memory-wipe and sometimes assassinate unidentified flying object (UFO) witnesses to keep them silent about what they have seen. The term is also frequently used to describe ...
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.
This list includes superclusters, galaxy filaments and large quasar groups (LQGs). The structures are listed based on their longest dimension. This list refers only to coupling of matter with defined limits, and not the coupling of matter in general (such as, for example, the cosmic microwave background, which fills the entire universe). All ...
The object itself was detected in ESO images dating back to 1980, but its identification as a quasar occurred only several decades later. [2]An automated analysis of 2022 data from the European Space Agency's Gaia satellite did not confirm J0529-4351 as too bright to be a quasar, and suggested it was a 16th magnitude star with a 99.98% probability.
