New NuSTAR observation and historical review indicate an initial strong shock near the red giant in RS Oph produces both gamma-ray particle acceleration and 0.2-30 keV thermal X-rays, with gamma-ray flux from Fermi inconsistent and implications for T CrB.
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.
