NASA’s Hubble Pinpoints Roaming Massive Black Hole
- NASA's Hubble Space Telescope has discovered a massive black hole roaming 600 million light-years away, consuming stars in a tidal disruption event (TDE).
- The new TDE, named AT2024tvd, revealed a wandering supermassive black hole that is offset from the center of the galaxy, a rare find among TDE events.
- This offset black hole weighs one million solar masses and coexists with a 100 million solar mass central black hole within the same galaxy.
- The TDE phenomenon involves a star being ripped apart by a black hole's gravitational forces, leading to the formation of a disk around the black hole and the emission of high-temperature radiation.
- The flare from the TDE was detected by ground-based telescopes and confirmed by NASA's Chandra X-ray Observatory, with Hubble pinpointing the event's location within the galaxy.
- The black hole responsible for the TDE is suspected to have been ejected from the galaxy's center due to three-body interactions or may be a remnant from a past galaxy merger.
- Future telescopes like the Vera C. Rubin Observatory and NASA's Nancy Grace Roman Space Telescope will aid in further understanding transient events like TDEs.
- This discovery opens up possibilities for uncovering more wandering black holes and sheds light on the dynamics of supermassive black holes in galaxies.
- The collaborative efforts of telescopes like Hubble and Chandra enable scientists to study and track rare celestial events, enhancing our knowledge of the universe.
- Hubble's continued operation and groundbreaking discoveries underscore its vital role in advancing astrophysical research and understanding the cosmos.
