We review theories of dark matter (DM) beyond the collisionless paradigm, known as self-
interacting dark matter (SIDM), and their observable implications for astrophysical structure …

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 and properties of neutrinos are among the most pressing issues in
contemporary particle physics. The dual-phase xenon time-projection chamber is the …

Astrophysical observations spanning dwarf galaxies to galaxy clusters indicate that dark
matter (DM) halos are less dense in their central regions compared to expectations from …

We study the distribution of cold dark matter (CDM) in cosmological simulations from the
FIRE (Feedback In Realistic Environments) project, for M*∼ 104–11 M⊙ galaxies in M h∼ …

The rotation curves of spiral galaxies exhibit a diversity that has been difficult to understand
in the cold dark matter (CDM) paradigm. We show that the self-interacting dark matter …

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 present the first simulations within an effective theory of structure formation (ETHOS),
which includes the effect of interactions between dark matter and dark radiation on the linear …

While astrophysical and cosmological probes provide a remarkably precise and consistent
picture of the quantity and general properties of dark matter, its fundamental nature remains …

Core formation and runaway core collapse in models with self-interacting dark matter (SIDM)
significantly alter the central density profiles of collapsed haloes. Using a forward modelling …
