The track of an elusive, energetic neutrino points to a distant galaxy as its source and VLA observations suggest high-energy particles may be generated in superfast jets of material near the galaxy’s core.
Distant Quasar Providing Clues to Early-Universe Conditions
The sharp radio “vision” of the VLBA gives astronomers a detailed look at a galaxy as it appeared when the Universe was a small fraction of its current age, giving clues about conditions at that early time.
Astronomers See Distant Eruption as Black Hole Destroys Star
Years-long observation program surprises astronomers with evidence of a star’s violent death near the core of a distant galaxy.
VLBA Finds Closest Pair of Supermassive Black Holes
The VLBA finds the closest pair of supermassive black holes yet found, orbiting each other at the core of a distant galaxy.
Astronomers Detect Orbital Motion in Pair of Supermassive Black Holes
VLBA images detect orbital motion of two supermassive black holes as they circle each other at the center of a distant galaxy.
