abstract

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 dark disks could explain a variety of observed phenomena, including periodic comet impacts. Using the first data release from the $Gaia$ space observatory, we search for a dark disk via its effect on stellar kinematics in the Milky Way. Our new limits disfavor the presence of a thin dark matter disk, and we present updated measurements on the total matter density in the Solar neighborhood.

  1. New Limits on Charged Dark Matter from Large-Scale Coherent Magnetic Fields

    astro-ph.CO 2019-08 conditional novelty 7.0 of 10

    The intact interstellar gas disk of the Milky Way implies charged dark matter must have charge-to-mass ratio below about 10^-13 e/GeV, unless it makes up only a small fraction of dark matter.

  2. Gravity Probe-DM: The Gravitational Laboratory for Dark Matter

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Proposal for a heliocentric two-spacecraft ranging mission (Gravity Probe-DM) to measure the tidal field of the Sun's dark-matter focusing wake, with raw range scales of ~0.6 pm to ~15 nm.

  3. Halo-Independent Quantum Sensor Probes of Low-Velocity Dark Matter

    hep-ph 2026-06 unverdicted novelty 6.0 of 10

    A halo-independent method using quantum sensors to probe and reconstruct the local dark matter velocity distribution from direct detection data.

  4. Empirical Modeling of Magnetic Braking in Millisecond Pulsars to Measure the Local Dark Matter Density and Effects of Orbiting Satellite Galaxies

    astro-ph.HE 2025-01 conditional novelty 6.0 of 10

    A spin-down based empirical model for magnetic braking doubles the sample of pulsar acceleration measurements and yields a direct local dark matter density of 0.0098 +/- 0.0025 solar masses per cubic parsec.
