Self-Interacting Dark Matter is an attractive alternative to the Cold Dark Matter paradigm only if it is able to substantially reduce the central densities of dwarf-size haloes while keeping the densities and shapes of cluster-size haloes within current constraints. Given the seemingly stringent nature of the latter, it was thought for nearly a decade that Self-Interacting Dark Matter would be viable only if the cross section for self-scattering was strongly velocitydependent. However, it has… Expand

Dark matter self-interactions from the internal dynamics of dwarf spheroidals
Dwarf spheroidal galaxies provide well-known challenges to the standard cold and collisionless dark matter scenario1,2: the too-big-to-fail problem (namely the mismatch between the observed massExpand
Constraining self-interacting dark matter with scaling laws of observed halo surface densities
The observed surface densities of dark matter halos are known to follow a simple scaling law, ranging from dwarf galaxies to galaxy clusters, with a weak dependence on their virial mass. Here weExpand

Dwarf galaxies in CDM and SIDM with baryons: observational probes of the nature of dark matter
We present the first cosmological simulations of dwarf galaxies, which include dark matter self-interactions and baryons. We study two dwarf galaxies within cold dark matter, and four differentExpand
Diverse dark matter density at sub-kiloparsec scales in Milky Way satellites: Implications for the nature of dark matter
Milky Way (MW) satellites reside within dark matter (DM) subhalos with a broad distribution of circular velocity profiles. This diversity is enhanced with the inclusion of ultrafaint satellites,Expand
Diversity in density profiles of self-interacting dark matter satellite halos
We present results from N-body simulations of self-interacting dark matter (SIDM) subhalos, which could host ultra-faint dwarf spheroidal galaxies, inside a Milky-Way-like main halo. We find thatExpand
