Quasars, the brightest objects in the cosmos, could act as cosmic signposts, directing astronomers to elusive pairs of supermassive black holes. Though scientists are aware that supermassive black ...
The Gemini North telescope and Subaru Telescope have been used to discover most distant merging quasars yet, "seen over 900 ...
The quasars are powered by black holes that are up to ten billion times the mass of the Sun. The black hole's gravity pulls in matter which forms a rotating disk around the black hole called an ...
This illustration depicts two quasars in the process of merging. Using both the Gemini North telescope, one half of the International Gemini Observatory, which is supported in part by the US ...
Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...
Quasars play a key role in our understanding of the history of the Universe, and possibly also the future of the Milky Way." Read more. about space and black holes.
The newly discovered double quasar, J121503.42–014858.7 and J121503.55–014859.3 — referred to as C1 and C2 by their discoverers — was spotted using the Subaru Telescope on Hawaii's Mauna ...
Both quasars and blazars are intrinsically the same. Both are active galaxies, and both harbor supermassive black holes with jets. The difference between blazars and quasars comes down to the ...
Quasars – the brightest and most powerful objects in the Universe – are ignited when galaxies collide, astronomers have said. These celestial objects can be a trillion times brighter than the ...
A quasar, or hyperactive supermassive black hole at the center of an early galaxy, is so luminous that it outshines our Milky Way galaxy by 100 times.
