Black holes and cosmic jets found to play key role in shaping galaxy evolution

A new study by Indian astronomers has revealed that supermassive black holes and the powerful jets they emit work in tandem to drive out gas from the centers of galaxies, effectively stalling the formation of new stars and influencing the overall evolution of galaxies. The study, conducted by a team at the Indian Institute of Astrophysics (IIA), an autonomous institute under the Department of Science and Technology (DST), has shed fresh light on how energetic processes near black holes—both r...

Astronomers get best view yet of two merging black holes

The merger of two black holes is a momentous event, revealing the wildest and most extreme configurations of space, time and gravity known to science. Researchers have now gotten their best look yet at such an event based on the detection of ripples in space-time called gravitational waves in an observation that lends strong support to hypotheses from eminent physicists Albert Einstein and Stephen Hawking. The collision occurred 1.3 billion light-years from Earth in a galaxy beyond our Milky W...
