The team observed two merging galaxies and discovered that the energy from a quasar is actively transforming the gas within its companion galaxy, thereby dictating whether new stars can form.

A new publication introduces the rapidly growing field of multi-messenger gravitational lensing, which combines gravitationally lensed signals, like gravitational waves, light or neutrinos to observe events in the universe.

A team of researchers, led by Prof. Keith Bannister at the Commonwealth Science and Industrial Research Organisation (CSIRO) in Australia, observed a burst of radio waves, three-billion light years away, using the Australian Square Kilometre Array Pathfinder (ASKAP) telescope. This could shed light on the ‘missing matter’.

Born on 26th November, 1926, in Jhang, in undivided Punjab, Dr. Yash Pal was an Indian scientist, educator, science communicator and educationist. After completing his M.Sc. degree in Physics from Panjab University, he moved to the Massachusetts Institute of Technology for his PhD. His areas of specialisation included cosmic rays.

A galaxy supercluster is the largest known structure in the Universe, made of dozens of galaxy clusters, themselves containing thousands of galaxies. The Saraswati Supercluster, discovered this year by a team of Indian scientists, is the largest known galaxy cluster today. It extends over 650 million light years across and weighs more than 20 billion suns would. We caught up with Prof. Joydeep Bagchi, who led the team that discovered Saraswati Supercluster, for a chat about the importance and implications of the discovery.
