Semi-Analytic Predictions for Strong-Lensing Perturbers in Cold and Self-Interacting Dark Matter
Jonathan Tekverk, Duncan K. Adams, Simon Birrer +2
Strong gravitational lensing is sensitive to the abundance and internal structure of dark matter halos, providing a probe of gravothermal evolution in self-interacting dark matter…
Statistical imprints of wave-like dark matter on multiply-imaged galaxies in strong cluster lenses from JWST
Nino Ephremidze, Daniel Gilman, Cora Dvorkin
Wave-like dark matter (DM) is an elusive dark matter (DM) candidate. The model, often also called fuzzy or ultralight DM, proposes that DM is an extremely light (…
LSST Strong Lensing Systems Dark Matter Sensitivity Analysis with Neural Ratio Estimators
Andreas Filipp, Yashar Hezaveh, Laurence Perreault-Levasseur +2
Strong gravitational lensing offers a unique probe of dark matter (DM) on sub-galactic scales, where the abundance and distribution of low-mass halos are highly sensitive to the un…
Dark Matter Subhalos and Higher Order Catastrophes in Gravitational Wave Lensing
Luka Vujeva, Jose María Ezquiaga, Daniel Gilman +2
Gravitational lensing is an invaluable probe of the nature of dark matter, and the structures it forms. Lensed gravitational waves in particular allow for unparalleled sensitivity…
