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.

abstract
Using publicly available Monte Carlo codes as well as compilation of published data on p--p interactions for proton kinetic energy below 2 GeV, we parametrize the energy spectra and production rates of $\gamma$-rays by simple but quite accurate ($\leq 20 \%$) analytical expressions in a broad range from the kinematic threshold to PeV energies.

Diffuse gamma-ray emission detected toward Berkeley 87 with 0.36° extension and photon index 2.68, favoring a hadronic origin due to dense gas and stellar winds.
MINOT modeling of Abell 3667 predicts hadronic gamma-ray flux roughly matching Fermi-LAT observations in the 1-300 GeV band but with a spectral index in tension with the data.
CTAO simulations exclude Cassiopeia A, RX J1713.7-3946, and HESS J1731-347 as PeVatrons via PTS metric while HAWC J2227+610 stays inconclusive, with 100 hours required to resolve proton cut-offs near 600 TeV.
Reviews IceCube neutrino results, models Galactic plane flux from cosmic ray interactions with the interstellar medium, and discusses prospects for identifying PeVatrons via LHAASO sources.
