Galaxies and their dark-matter haloes have posed several challenges to the dark energy
plus cold dark matter (Λ CDM) cosmological model. These discrepancies between …

The cold dark-matter model successfully explains both the emergence and evolution of
cosmic structures on large scales and, when we include a cosmological constant, the …

The properties of low-mass dark matter (DM) halos appear to be remarkably diverse relative
to cold, collisionless DM predictions, even in the presence of baryons. We show that self …

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 …

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 …

Fuzzy dark matter (FDM) is a dark matter candidate consisting of ultralight scalar particles
with masses around, a regime where cold bosonic matter behaves as a collective wave …

It has been proposed that gravothermal collapse due to dark matter self-interactions (ie self-
interacting dark matter, SIDM) can explain the observed diversity of the Milky Way (MW) …

We compare proposed solutions to the core vs cusp issue of spiral galaxies, which has also
been framed as a diversity problem, and demonstrate that the cuspiness of dark matter halos …

The presence of a central baryonic potential can have a significant impact on the
gravothermal evolution of self-interacting dark matter (SIDM) haloes. We extend a semi …

We introduce the TangoSIDM project, a suite of cosmological simulations of structure
formation in a Λ-self-interacting dark matter (SIDM) universe. TangoSIDM explores the …
