Abstract The standard Λ Cold Dark Matter (ΛCDM) cosmological model provides a good
description of a wide range of astrophysical and cosmological data. However, there are a …

New Particles Beyond the Standard Model have always been thought to be charged under
at least some of the same gauge interactions of ordinary particles. Although this assumption …

The strong discrepancy between local and early-time (inverse distance ladder) estimates of
the Hubble constant H 0 could be pointing towards new physics beyond the concordance Λ …

Self-interacting dark matter (SIDM) arises generically in scenarios for physics beyond the
Standard Model that have dark sectors with light mediators or strong dynamics. The self …

We study the direct detection prospects for a representative set of simplified models of sub-
GeV dark matter (DM), accounting for existing terrestrial, astrophysical and cosmological …

We find that a uniform scaling of the gravitational free-fall rates and photon-electron
scattering rate leaves most dimensionless cosmological observables nearly invariant. This …

The existence of millicharged dark matter (mDM) can leave a measurable imprint on 21-cm
cosmology through mDM-baryon scattering. However, the minimal scenario is severely …

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 …

Abstract Planckian Interacting Dark Matter (PIDM) is a minimal scenario of dark matter
assuming only gravitational interactions with the standard model and with only one free …
