Not so dark, not so dense: an alternative explanation for the lensing subhalo in SDSSJ0946+1006
Qiuhan He, Andrew Robertson, James W. Nightingale +12
Previous studies of the strong lens system SDSSJ0946+1006 have reported a dark matter subhalo with an unusually high central density, potentially challenging the standard cold dark…
Probing Dark Matter Substructures with Free-Form Modelling: A Case Study of the `Jackpot' Strong Lens
Xiaoyue Cao, Ran Li, James W. Nightingale +12
Characterising the population and internal structure of sub-galactic halos is critical for constraining the nature of dark matter. These halos can be detected near galaxies that ac…
Galaxy Mass Modelling from Multi-Wavelength JWST Strong Lens Analysis: Dark Matter Substructure, Angular Mass Complexity, or Both?
Samuel C. Lange, Aristeidis Amvrosiadis, James W. Nightingale +8
We analyze two galaxy-scale strong gravitational lenses, SPT0418-47 and SPT2147-50, using JWST NIRCam imaging across multiple filters. To account for angular complexity in the lens…
