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…
The "Little Dark Dot": Evidence for Self-interacting Dark Matter in the Strong Lens SDSS J0946+1006?
Shubo Li, Ran Li, Kaihao Wang +13
Previous studies, based on precise modeling of a gravitationally lensing image, have identified what may be an extremely compact, dark perturber in the well-known lensing system SD…
Pixel-level modelling of group-scale strong lens CASSOWARY 19
Hengkai Ding, Yiping Shu, Yun Chen +6
We present the first high-precision model for the group-scale strong lensing system CASSOWARY 19 (CSWA19), utilising images from the Hubble Space Telescope (HST). Sixteen member ga…
The COSMOS-Web Lens Survey (COWLS) II: depth, resolution, and NIR coverage from JWST reveal 17 spectacular lenses
Guillaume Mahler, James W. Nightingale, Natalie B. Hogg +27
The COSMOS-Web Lens Survey (COWLS) presents the first systematic search for strong gravitational lenses in the COSMOS-Web field using data from the \textit{James Webb} Space Telesc…
The COSMOS-Web Lens Survey (COWLS) I: Discovery of >100 high redshift strong lenses in contiguous JWST imaging
James Nightingale, Guillaume Mahler, Jacqueline McCleary +27
We present the COSMOS-Web Lens Survey (COWLS), a sample of over 100 strong lens candidates from the \,deg COSMOS-Web survey, discovered using exquisite James Webb Space T…
Measuring the Stellar-to-Halo Mass Relation at Solar masses, using forthcoming space-based imaging of galaxy-galaxy strong lenses
Kaihao Wang, Xiaoyue Cao, Ran Li +11
The stellar-to-halo mass relation (SHMR) is central to understanding the co-evolution of galaxies and their host dark matter haloes, yet it remains weakly constrained for dwarf gal…
