Indian Astronomers discover rare double radio relic system in galaxy cluster Abell 2108, May 2024

A team of Indian astronomers, led by Swarna Chatterjee from the Indian Institute of Technology Indore, discovered a faint radio emission spanning 2 million light-years in the low-mass galaxy cluster Abell 2108 (A2108) using the upgraded Giant Metrewave Radio Telescopes (uGMRT) near Pune. This discovery makes this cluster as a rare double radio relic system and provides crucial insights into the formation and evolution of galaxy clusters.
