Exploring the Nature of Galactic Unassociated Sources Detected by the Fermi-LAT

F. Acero, A. Acharyya, A. Adelfio, M. Ajello, E. Aviano, L. Baldini, et al.

Abstract We investigate the nature of the unassociated sources detected by the Fermi-LAT close (∣ b ∣ < 10°) to the Galactic plane, representing 16% of all sources in the 4FGL-DR4 catalog. The bulk of these sources (referred to as soft Galactic unassociated sources, SGUs) exhi…

Bridging Ab Initio Symmetries and Global Nuclear Masses with Interpretable Neural Networks

Phong Dang, Evander Espinoza, Xiaoliang Wan, Michela Negro, Jerry P. Draayer, Feng Pan, et al.

Ab initio modeling has established Wigner's SU(4) and Elliott's SU(3) as dominant symmetries of the nuclear force in light and intermediate-mass nuclei. We ask whether they also govern nuclear binding across the entire chart. Our aim is not high-precision prediction but physical…
