Using the Karl G. Jansky Very Large Array (VLA) and the upgraded Giant Meter Radio Telescope (uGMRT), astronomers have conducted multi-wavelength observations of a galaxy merger remnant known as Mrk 212. Results of this observational ...
Over the past five years, astronomy has been revolutionised as scientists have used ripples in the fabric of spacetime, called gravitational waves, to reveal the secrets of the previously hidden world of black holes. Gravitational ...
