TL;DR
This paper presents evidence of shock-shock interaction in the jet of blazar CTA 102, based on spectral evolution analysis during a major radio outburst, revealing complex jet dynamics.
Contribution
It introduces observational evidence for shock-shock interaction in a blazar jet through spectral analysis during a significant outburst.
Findings
Evidence of shock-shock interaction in CTA 102's jet
Spectral evolution supports shock interaction hypothesis
Analysis during a major radio outburst
Abstract
We have found evidence for interaction between a standing and a traveling shock in the jet of the blazar CTA 102. Our result is based in the study of the spectral evolution of the turnover frequency-turnover flux density plane. The radio/mm light curves were taken during a major radio outburst in April 2006.
