Indian Scientists Discover Galaxy with Four Cycles of Black Hole Activity
Scientists from IISER Pune and NCRA-TIFR have identified the first known radio galaxy, J023721.13-010528.5, whose central supermassive black hole has undergone four distinct phases of activity. Spanning about 4.2 million light-years with an S-shaped structure, the galaxy's jets of energetic particles restarted multiple times over millions of years. The study, led by Pavan Khadekar and published in The Astrophysical Journal, used data from India's GMRT, the US's Very Large Array, and South Africa's MeerKAT telescope.
