Astronomers using NASA’s Hubble Space Telescope observed a massive black hole consuming a star 600 million light-years away in a rare cosmic event known as a tidal disruption event (TDE).
The TDE, named AT2024tvd, is unique as it occurred far from the center of its host galaxy, indicating the presence of a 'wandering' black hole roaming through the galaxy's outskirts.
The galaxy hosting AT2024tvd contains two massive black holes, with the wandering one weighing about 1 million solar masses and was confirmed to be in an offset position.
The discovery of AT2024tvd sheds light on the existence of roaming black holes and may help in identifying more of them through similar tidal disruption events, as suggested by lead study author Yuhan Yao of UC Berkeley.
