Overview

• AT2024tvd marks the first tidal disruption event discovered outside a galaxy's core, detected 600 million light-years away by the Zwicky Transient Facility.
• The event involves a supermassive black hole, about 1 million times the mass of the Sun, devouring a star while orbiting 2,600 light-years from its host galaxy's center.
• Multi-wavelength observations from Hubble, Chandra, and other facilities confirmed the black hole's location and its dramatic flare across the electromagnetic spectrum.
• Two theories are being investigated for the black hole's displacement: ejection from a three-body interaction or as a remnant from a galaxy merger.
• This discovery demonstrates the potential of tidal disruption events to uncover hidden black holes and sets the stage for future findings with observatories like Vera Rubin and Roman Space Telescope.
