Blast From Black Holes Can Stunt The Growth Of Stars, Says Study


Astronomers have discovered mysterious wind storm that emerges from the center of galaxies. They stated that the explosion of wind is so powerful that it can disturb formation of new stars in host galaxy.

Using two different telescopes of NASA and ESA; XMM-Newton and Nuclear Spectroscopic Telescope Array, astronomers from NASA have found the furiously strong winds from supermassive black holes located at the center of galaxies. They stated that these blasts of winds are so strong that they can actually reshape star formation. These black holes are the source of high-power winds and radiation which carries phenomenal amount of energy throughout the galaxy. In effect, these gusts are strong enough to not only stunt the formation of stars but to also affect the evolution of the galaxy they reside in.

The black hole, which is being analyzed for this study, is called PDS-456. It is residing in the middle of a galaxy that is over 2 billion light years away from Earth, and emitting super-fast winds and radiation.

For their study, the astronomers calculated the speed, size as well as shape of the winds that surround the black holes. This helped them in finding out the affect of these forces on their galaxies. Black holes are very dense collections of matter that are formed at a time when stars collapse on themselves.

They stated that the gravitational pull is very strong which does not let anything escape, even light. This study reveals that the high-velocity winds known as quasar winds that surround black holes affect their galaxies. The winds increase in proportion with the development of the black hole, expelling gas outward.

According to the astronomers, a black hole as well as its galaxy are together involved in an astronomical balancing act. This implies that with the expansion of a galaxy, the black hole residing at its center works to inhibit the growth and also stops the formation of new stars.

The study has helped the astronomers in understanding the behavior of quasar winds. Instead of originating from a black hole in one direction, the winds emanate from it in a circular gust.

The findings were published in the Science journal.
