Constraining resonant dark matter self-interactions with strong gravitational lenses

D Gilman, YM Zhong, J Bovy - Physical Review D, 2023 - APS
We devise a method to constrain self-interacting dark matter (SIDM) from observations of
quadruply imaged quasars, and apply it to five self-interaction potentials with a long-range …
