New Triple-Galaxy System Challenges Black Hole Evolution Theory

Summary

Story summary

The Stingray is a triple-galaxy system discovered by astronomers, dating to 1.1 billion years after Big Bang.
It contains a transitional little red dot (tLRD) with features of active galactic nuclei and little red dots (LRDs), but lacks an LRD signature.
Researchers say galaxy interactions triggered bursts of star formation, influencing black hole's activity.
If verified, the finding could mean LRDs are a phase in black hole evolution, not distinct.
