An international observing campaign, including radio observations with the Allen Telescope Array (ATA), has discovered an unprecedented burst of radio activity from a tidal disruption event (TDE).
TDEs occur when a star wanders too close to a supermassive black hole (SMBH) and is ripped apart by its strong gravitational forces, lighting up the cosmos across all wavelengths.
These events light up the cosmos across all wavelengths, from visible and X-ray light to radio waves.
The particular TDE, named AT 2024tvd, stands out from others as it evolved at record-breaking speed and took place off-center, away from the nucleus of its galaxy.
