New Delhi: Researchers from the Indian Institute of Astrophysics have investigated the influence of gas outflows as well as radiations from supermassive black holes occupying the hearts of galaxies, on the surrounding galaxies. Both of these processes drive away gas and dust from the galaxy, the raw material from which new stars are formed. As a result, powerful and active supermassive black holes quench star formation in the surrounding galaxies. The researchers wanted to better understand why some galaxies have very low star formation rates. The research reveals that both the processes, the black hole winds as well as the radiation play a role in quenching star formation, and regulating the growth of the surrounding galaxies.
