Quasars are the brightest and most powerful objects in the galaxy, and scientists have recently been able to solve the biggest mystery related to these celestial objects. In a recent study, they found that quasars are activated and illuminated by the collision of galaxies.
According to Phys, a group of researchers from the University of Sheffield and Hertfordshire say that quasars, which were first discovered about 60 years ago, are caused by Collision of galaxies They activate and produce a brightness equivalent to trillions of stars.
Researchers discovered these collisions when using deep imaging observations Isaac Newton’s telescope in La Palmasaw the tangled structures of the outer regions of galaxies that host quasars.
Most galaxies have a supermassive black hole at their center. These galaxies also contain a lot of mass gas are, but most of these gases are circulating at a great distance from the center of galaxies and are safe from black holes.
Where does the extremely intense energy of quasars come from?
But the collision between the galaxies sends these gases towards the black holes in the center of the galaxy. Then, just before these gases are swallowed up by the black hole, A tremendous amount of energy It is emitted in the form of radiation and creates the special glow of quasars.
The activation of quasars can have significant consequences for galaxies. This event may remove the rest of the gases from the galaxies Out slow and prevent the formation of new stars for billions of years.
This is the first time that scientists have been able to observe a quasar with this level of sensitivity. They are by observation 48 asteroids and their host galaxy have concluded that these galaxies are ca Three times more from other galaxies are exposed to the possibility of collision or interaction with other galaxies.
This study is an important step to increase our knowledge about the formation and energy supply of quasars. Professor Cleo Tedhanter of the University of Sheffield’s Physics and Astronomy Unit says: “Outbreaks are one of the most intense phenomena in the universe, and what we see from them is probably indicative of what will happen in about five billion years when The collision of the Milky Way with the Andromeda Galaxy it happens.”
Scientists say that Earth is not going to come close to any quasars anytime soon. However, researchers monitor these phenomena to learn more about the history of the universe and the future of the Milky Way. The results of this study have been published in the journal Monthly Notices of the Royal Astronomical Society.
