Quasars tsunamis can stop the formation of stars

Quasars are considered the brightest objects in the Universe. They arise when supermassive black

hole, which is located in the center almostEach galaxy gets too much gas. As a result, the gravitational energy of the fall is converted into heat and light, and a bright jet appears around the black hole.

It is believed that quasars occur most oftendue to the collision of galaxies, when there is a huge amount of gas near the black hole. However, as a result, its radiation in the brightest stage pushes dust and gas out of its surroundings, the quasar itself goes out, and the star formation process stops in the galaxy itself.

This process occurs under the action of quasarwinds, extremely high-energy energy flows that spread across the galactic disk, violently sweeping away the material that could form new stars

In a new study using the Hubble telescope, scientists found that these winds - a kind of cosmic tsunami - dramatically heat up the gas and dust they pass through.

Material can heat up to a billiondegrees, after which it begins to glow over the entire visible spectrum. According to the authors of the study, this effect may explain the reason why scientists still have not been able to detect a large number of large galaxies outside the Milky Way - it is likely that tsunamis on quasars create light pollution that does not allow them to be seen.

Previously, astrophysicists from the University of Kansasdiscovereda new type of space objects - “cold quasars”. This discovery will fill a gap in the study of galaxy evolution.
