Our Sun lies within 300 parsecs of the 2.7-kiloparsecs-long sinusoidal chain of dense gas
clouds known as the Radcliffe Wave. The structure's wave-like shape was discovered using …

The growing trove of precision astrometric observations from the Gaia space telescope and
other surveys is revealing the structure and dynamics of the Milky Way in ever more …

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 …

Dark sector theories naturally lead to multicomponent scenarios for dark matter where a
subcomponent can dissipate energy through self-interactions, allowing it to efficiently cool …

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 …

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 …

The non-linear process of cosmic structure formation produces gravitationally bound
overdensities of dark matter known as halos. The abundances, density profiles, ellipticities …

Using the method that was developed in the first paper of this series, we measured the
vertical gravitational potential of the Galactic disk from the time-varying structure of the …

I selectively review the theoretical properties and observational limits pertaining to dark
atoms, as well as composite dark matter candidates bound by a confining gauge interaction …

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 …
