Astronomical transients, sudden changes in celestial brightness, offer insights into violent cosmic events. Renowned astronomer Shrinivas Kulkarni was honored with the 2024 Shaw Prize for his contributions to understanding these phenomena. Supernovae, explosive deaths of massive stars, and active galactic nuclei (AGN), powered by supermassive black holes, showcase dazzling fluctuations in brightness. A more recent enigma, fast radio bursts (FRBs), emit intense energy bursts in milliseconds, challenging astronomers with their elusive origins.
