The Radio Flare Arrived Three Years Down the Jet
An extended-jet model links TXS 0506+056's high-energy episode with its much later radio brightening.
Summary
An extended-jet model links TXS 0506+056's high-energy episode with its much later radio brightening.
Instead of treating the blazar as one compact emission zone, the model follows electrons along a parsec-scale evolving jet and fits multi-frequency light curves. The authors find that the moving plasma can meet an older cooled-electron population near the radio-core edge, producing a delayed enhancement after the 2017 neutrino-associated episode. The fit suggests a causal pathway, but it does not by itself prove that the blazar produced the IceCube neutrino.
Why it matters
