Abstract Weakly Interacting Massive Particles (WIMPs) are among the best-motivated dark
matter candidates. No conclusive signal, despite an extensive search program that …

Dark matter interactions with electrons or protons during the early Universe leave imprints
on the cosmic microwave background and the matter power spectrum, and can be probed …

The cosmic radio-frequency spectrum is expected to show a strong absorption signal
corresponding to the 21-centimetre-wavelength transition of atomic hydrogen around …

A bstract We consider the constraints from Supernova 1987A on particles with small
couplings to the Standard Model. We discuss a model with a fermion coupled to a dark …

We present the first limits on inelastic electron-scattering dark matter and dark photon
absorption using a prototype SuperCDMS detector having a charge resolution of 0.1 …

Direct detection strategies are proposed for dark matter particles with MeV to GeV mass. In
this largely unexplored mass range, dark matter scattering with electrons can cause single …

Cosmic inflation provides a window to the highest energy densities accessible in nature, far
beyond those achievable in any realistic terrestrial experiment. Theoretical insights into the …

The dynamics of our Universe is strongly influenced by pervasive—albeit elusive—dark
matter, with a total mass about five times the mass of all the baryons,. Despite this, its origin …

If dark matter has a large self-interaction scattering cross-section, then interactions among
dark-matter particles will drive galaxy and cluster haloes to become spherical in their …

In this work we derive simple closed-form expressions for the dynamical friction acting on
black holes moving through ultralight (scalar field) dark matter, covering both nonrelativistic …
