NSF VLA Reveals Supermassive Black Holes Emit Radio "Burps" Years After Destroying Stars
A respectable bake. You'd come back tomorrow for another.
Summary
Astronomers using the NSF Very Large Array have discovered that supermassive black holes continue to emit radio waves years after tearing apart a star in a tidal disruption event (TDE). These delayed "burps" of material slam into surrounding gas and glow in radio waves, providing new insights into how black holes grow and release energy into their galaxies. The research shows that the aftermath of these stellar destruction events is far more prolonged and complex than previously understood.

· 3 pulledAstronomers using the U.S. National Science Foundation Very Large Array (NSF VLA) have found that when a supermassive black hole tears apart an unlucky star, the fireworks are not over when the first flash fades.
Years after the initial outburst, many of these black holes 'burp' out streams of material that slam into surrounding gas and glow in radio waves.
Giving the NSF VLA a front‑row seat to how black holes grow and blast energy back into their galaxies.
