AB  - Understanding how electronic correlations reshape topological states remains a central challenge in quantum materials. Here we investigate the uranium ferromagnet UPS using magnetotransport, angle-resolved photoemission spectroscopy, thermodynamic measurements, and first principles calculations. Resonant photoemission reveals narrow U-5f spectral weight at the Fermi level coexisting with broad incoherent states, consistent with the itinerant/localized duality characteristic of uranium 5f electrons. The anomalous Hall conductivity reaches approximately 4.5×10^2 Ω^−1cm^−1, yet does not simply follow the ordered magnetic moment. Temperature dependent photoemission reveals relatively little change across T_C=118~K, followed by a pronounced redistribution of low-energy 5f spectral weight below approximately 90~K. First-principles calculations identify a symmetry protected Weyl crossing with pronounced Berry curvature and yield an intrinsic anomalous Hall conductivity of approximately 9.6×10^2 Ω^−1cm^−1. These results demonstrate that magnetic order, correlated electronic reconstruction, and anomalous Hall transport develop over distinct but overlapping temperature ranges, revealing how strong correlations reshape topological transport in a uranium Weyl semimetal.
