  "abstract": "We present a comprehensive search for non-thermal high-energy γ -ray emission from the nearby merging galaxy cluster Abell 119 ( z = 0.044 ) using archival observations spanning over seven decades in photon energy. Our analysis combines hard X-ray data from INTEGRAL/ISGRI (30–100 keV), MeV γ -ray observations from COMPTEL (0.75–30 MeV), and GeV–TeV data from the DArk Matter Particle Explorer (DAMPE; 3 GeV–1 TeV). No statistically significant emission is detected at the cluster position in any energy band. In the hard X-ray regime, we derive a 3 σ upper limit of F 30 − 100 k e V ≲ 8.5 × 10 − 11 erg cm s from ISGRI mosaic imaging. Reanalysis of archival COMPTEL data yields 95% confidence-level upper limits ranging from ∼ 9 × 10 − 11 to ∼ 8 × 10 − 10 erg cm s across 0.75–30 MeV. In the GeV–TeV range, DAMPE places upper limits on the differential energy flux to ∼ 10 − 12 – 10 − 10 erg cm s (95% confidence level). These results provide independent multi-band constraints on the reported GeV excess from recent Fermi-LAT studies. While our DAMPE limits do not exclude the flux levels claimed in those analyses, the absence of confirmation across keV–MeV–GeV bands indicates that any non-thermal emission from Abell 119 remains tentative.",
