Scientists have discovered a Quasar Tsunami for the first time |


NASA's Hubble telescope discovered what is being called as 'most energetic outflow universe have ever witnessed and scientists have ever detected'. This outflow of energy is a QUASSAR TSUNAMI in the center of a distant galaxy.

Lets know about Quasars:

Quasar is a extremely luminous active galactic nucleus (AGN), in which a supe rmassive black hole with mass ranging from millions to billions of times the mass of the Sun is surrounded by a gaseous accretion disk. With time, the gasses are attracted by the gravitational pull black hole and it is emitted out in the form of electromagnetic radiation. This electromagnetic radiation is enormous in amount and can be observed in electromagnetic spectrum.

It is now known that quasars are distant but extremely luminous objects, so any light which reaches the Earth is red-shifted due to the metric expansion of space.

Quasars are believed—and in many cases confirmed—to be powered by accretion of material into super massive black holes in the nuclei of distant galaxies, as suggested in 1964 by Edwin Salpeter and Yakov  Zel'dovich. Light and other radiation cannot escape from within the event horizon of a black hole, but the energy produced by a quasar is generated outside the black hole, by gravitational stresses and immense friction within the material nearest to the black hole, as it orbits and falls inward.

The brightest quasar in the sky is 3C 273 in the constellation of Virgo. It has an average apparent magnitude of 12.8 (bright enough to be seen through a medium-size amateur telescope), but it has an absolute magnitude of −26.7.
In this universe, Gama ray burst is one of the most energetic phenomenon takes place and this quasar tsunami is even more energetic than Gama ray burst.
This quasar tsunami carries biggest amount of mechanical energy carried by any other  phenomenon in comparison to this one.

Hubble’s ultraviolet observations allow us to follow the whole range of energy output from quasars, from cooler gas to the extremely hot, highly ionized gas in the more massive winds,’ added team member Gerard Kriss of the space telescope science institute in Baltimore.

Numerical simulations of galaxy evolution suggest that such outflows can explain some important cosmological puzzles, such as why astronomers observe so few large galaxies in the universe, and why there is a relationship between the mass of the galaxy and the mass of its central black hole. This study shows that such powerful quasar outflows should be prevalent in the early universe.

Researchers have been already discovered a quasar carried huge amount of water which has never been discovered ever before and now this quasar tsunami. After these discoveries, it will be a real bluff to say 'there is no water outside the earth'. After studying 13 quasar outflow, astronomers found huge amount of water and gasses exploding out from these quasars.

The credit of this discovery totally goes to hubble space Telescope and the team of researchers includes graduate student Xinfeng Xu and postdoctoral researcher Timothy Miller, both of Virginia Tech, as well as Rachel Plesha of the Space Telescope Science Institute.
