A Dense Dark Matter Core of the Subhalo in the Strong Lensing System JVAS B1938+666

The nature of dark matter remains unknown, motivating the study of fuzzy/wave dark matter (FDM/ ψ DM) and self-interacting dark matter (SIDM) as alternative frameworks to address small-scale discrepancies in halo profiles inferred from observations. This study presents a nonparametric reconstruction...
