There is a growing sense of 'crisis' in the dark-matter particle community, which arises from
the absence of evidence for the most popular candidates for dark-matter particles—such as …

The nature of dark matter is one of the most pressing questions in physics. Yet all our
present knowledge of the dark sector to date comes from its gravitational interactions with …

The nature of dark matter remains one of the key science questions. Weakly Interacting
Massive Particles (WIMPs) are among the best motivated particle physics candidates …

Galactic rotation curves exhibit diverse behavior in the inner regions while obeying an
organizing principle; ie, they can be approximately described by a radial acceleration …

We perform a high-resolution cosmological zoom-in simulation of a Milky Way (MW)–like
system, which includes a realistic Large Magellanic Cloud analog, using a large differential …

We probe the self-interactions of dark matter with relaxed galaxy groups and clusters using
observational data from strong and weak lensing and stellar kinematics. Our analysis uses …

We use a new mass modelling method, GravSphere, to measure the central dark matter
density profile of the Draco dwarf spheroidal galaxy. Draco's star formation shut down long …

Self-interacting dark matter (SIDM) cosmologies admit an enormous diversity of dark matter
(DM) halo density profiles, from low-density cores to high-density core-collapsed cusps. The …

We present bahamas-SIDM, the first large-volume,, cosmological simulations including both
self-interacting dark matter (SIDM) and baryonic physics. These simulations are important for …

Dark matter in the cosmological concordance model is parametrized by a single number,
describing the covariantly conserved energy density of a nonrelativistic fluid. Here we test …
