Studying the smallest self-bound dark matter structure in our Universe can yield important clues about the fundamental particle nature of dark matter. Galaxy-scale strong gravitational lensing provides a unique way to detect and characterize dark matter substructures at cosmological distances from the Milky Way. Within the cold dark matter (CDM) paradigm, the number of low-mass subhalos within lens galaxies is expected to be large, implying that their contribution to the lensing convergence… Expand

Small-scale shear: Peeling off diffuse subhalos with gravitational waves
Subhalos at subgalactic scales (M . 10M or k & 10 Mpc−1) are pristine testbeds of dark matter (DM). However, they are too small, diffuse and dark to be visible, in any existing observations. In thisExpand

Strong gravitational lensing is a promising way of uncovering the nature of dark matter, by finding perturbations to images that cannot be well accounted for by modeling the lens galaxy withoutExpand

Constraints on the identity of the dark matter from strong gravitational lenses
The cold dark matter (CDM) cosmological model unambiguously predicts that a large number of haloes should survive as subhaloes when they are accreted into a larger halo. The CDM model would be ruledExpand
