An active repeating fast radio burst in a magnetised eruption environment

March 14, 2025

Fast radio bursts (FRBs) are millisecond-duration radio pulses of extragalactic origin with largely unknown progenitors. Some FRBs show mild variations in their magneto-ionic environment, possibly due to plasma turbulence or […]

Processing of GASKAP-Hi pilot survey data using a commercial supercomputer
