Indian astronomers have identified new clues about the sources of X-ray emission from some of the Universe’s most energetic objects, offering insights into the extreme physical conditions surrounding blazars and the mechanisms that power active galaxies. The study was conducted by researchers from the Aryabhatta Research Institute of Observational Sciences (ARIES), Nainital, an autonomous institute under the Department of Science and Technology. Blazars are active galaxies powered by supermassiv
