Deep VERITAS observations detect extended TeV gamma rays from the jet lobes of SS 433, consistent with leptonic acceleration and no central source emission.
Fermi LAT data analysis detects a time-evolving ~162-day periodic GeV signal from 4FGL J1913.2+0512 linked to SS 433, prominent in 2008-2018 but diminished afterward, indicating multi-year evolution in gamma-ray production efficiency or geometry.
Feasibility proposal for SKA-Low radio detection of PeV gamma-ray air showers from galactic PeVatrons.
A review of extreme gamma-ray transients defined as catastrophic events or extreme particle acceleration regimes, covering diagnostics, instruments, and source classes.
