India, Oct. 21 -- The Government of India has issued a release:
Black hole activities suppress the birth of new stars around it, shows a new study that can help in a deeper understanding of how galaxies evolve and may provide answers to why some have very low star-formation rates.
Supermassive black holes at the centres of galaxies are known to drive outflows of gas, and astronomers have long studied how feedback processes from these outflows can in turn determine the evolution of these galaxies. However, a key puzzle has been to understand the relative influence of this gas outflow versus radiation from the central regions on the behaviour and evolution of the host galaxy.
A new study led by astronomers at the Indian Institute of Astrop...
