Multi-wavelength MCMC modeling of RCW 38 supports hadronic gamma-ray production with K_ep ≲ 10^{-3} and acceleration efficiency ≳1%, consistent with cosmic-ray composition requirements.
DAMPE independently detects the Fermi bubbles at 26 sigma and the Galactic center GeV excess at 7 sigma, with the excess spectrum and morphology matching Fermi-LAT and fitting a 50 GeV dark matter particle annihilating to b quarks.
New VERITAS observations of the 2017 VHE flare from NGC 1275, with multiwavelength SEDs, support a two-component blob-in-jet model placing gamma-ray emission near the C3 radio component at a 10-degree viewing angle.
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.
Fermi-LAT and CO data support a hadronic PeVatron scenario for LHAASO J1912+1014u with proton index ~2.2 and total energy (1-5) x 10^49 erg above 1 GeV.
Fermi-LAT detects point-like gamma-ray emission from SNR B0453-685, with broadband modeling favoring an evolved PWN impacted by the SNR reverse shock and possible pulsar contribution below 5 GeV.
Multi-instrument analysis interprets HESS J1857+026 as a pulsar wind nebula with age 16-21 kyr and B-field 0.4-1.6 μG, plus possible hadronic emission below 10 GeV and suppressed local diffusion.
