Fastest-Evolving Radio Signals from Distant Tidal Disruption Event

Summary

Story summary

Astronomers have identified a tidal disruption event named AT 2024tvd, 2,600 light-years from its galaxy's center, that produced the fastest-evolving radio signals recorded, with two bursts.
The findings suggest supermassive black holes can exist away from galactic centers, possibly due to past galactic mergers.
Researchers note material was ejected months after star's destruction, signaling complex processes behind black hole activity.
The study will be published in The Astrophysical Journal Letters.
