We all already know that black holes are huge stellar objects with highly powerful force of gravity. So powerful that even photons are not able to escape. Astronomers have concluded that the RF particles emitted by them can travel almost as fast as light itself.
A research conducted by Megan Gralla with a few colleagues at the John Hopkins university led them to believe that these stellar objects commonly referred to as black holes also have the ability to hinder the formation of stars in age old galaxies.
According to the study, when these holes get big enough, the emanating particles begin to interrupt the collapsing and cooling of hot gasses which serves as a vital mechanism in the creation of new stars. Thus, prevent the formation of stars itself.
One of the assistant professors working in the study, Prof. Tobias Marriage said that active black holes serve as the sole purpose for galaxies to stop forming new stars.
However, this wasn’t the actual reason for the study in the first place. The reason the team took up this study was to mainly observe some interaction between the faint light and the hot gasses referred to them as the Sunyaev-Zel’dovich effect. It is this signature they wanted to look for. Though they didn’t exactly do what they wanted to, they figured out the reason for old galaxies to stop forming stars.
