As a part of a sky survey to map poorly-studied low-mass galaxy clusters, Indian astronomers have made a rare discovery of a “double radio-relic” or two radio wave emitting structures at the periphery of one single such galaxy-cluster.

A galaxy cluster is a structure that consists of anywhere from hundreds to thousands of galaxies bound together by the force of gravity. They are the largest objects in the universe and provide the closest picture of how the universe behaves.

“This study helps understand the dynamical evolution of galaxy clusters in much detail,” team leader Surajit Paul at Manipal Academy of Higher Education told DH.

This is something the Indian group has been exploring as they are surveying the sky with upgraded Giant Metrewave Radio Telescope near Pune – one of the world’s most sensitive radio telescopes - looking for low-mass galaxy clusters.
