Satellite galaxies of the Milky Way and of the Andromeda galaxy have been found to
preferentially align in significantly flattened planes of satellite galaxies, and available …

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 …

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 …

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 …

We formulate an effective theory of structure formation (ETHOS) that enables cosmological
structure formation to be computed in almost any microphysical model of dark matter …

We use stellar kinematics from the latest Gaia data release (DR2) to measure the local dark
matter (DM) density ρ DM in a heliocentric cylinder of radius R= 150 pc and half-height z …

Small-scale structure is studied in the context of dissipative dark matter, arising for instance
in models with a hidden unbroken Abelian sector, so that dark matter couples to a massless …

A bstract Atomic dark matter is a simple but highly theoretically motivated possibility for an
interacting dark sector that could constitute some or all of dark matter. We perform a …

If a component of the dark matter has dissipative interactions, it could collapse to form a thin
dark disk in our Galaxy that is coplanar with the baryonic disk. It has been suggested that …

We study the fragmentation scale of dark gas formed in dissipative dark-matter halos and
show that the simple atomic-dark-matter model consistent with all current observations can …
