Mapping Atomic Hydrogen in the Disk of the Milky Way [PDF]

, 2013
The VATLY radio telescope has been used to draw the map of atomic hydrogen gas in the disk of the Milky Way. Evidence has been obtained for its differential rotation, its cloud and arm structure and the presence of a dark matter ...

GD-1 and the Milky Way Starless Dark Matter Subhalos

The Astrophysical Journal
Measurements of the GD-1 star stream velocity distribution within ±3° of the centerline find a total line-of-sight velocity spread of 5–6 km s ^−1 in the-well measured ϕ _1  = [−30, 0] region.

Dynamics of Axion Clumps in the Milky Way halo to study Dark Matter

, 2022
In a wide variety of axion models, a relevant fraction of all Dark Matter (DM) is expected to bound in dense small-scale substructures, called axion miniclusters. Despite they enhance the local DM density, the crossing of miniclusters through Earth are rare events occurring once in 105 years making direct detection inefficient.

Preprint typeset using L ATEX style emulateapj v. 11/10/09 SLAC-PUB-15326 HALO-TO-HALO SIMILARITY AND SCATTER IN THE VELOCITY DISTRIBUTION OF DARK MATTER

, 2012
We examine the velocity distribution function (VDF) in dark matter halos from Milky Way to cluster mass scales. We identify an empirical model for the VDF with a wider peak and a steeper tail than a Maxwell–Boltzmann distribution, and discuss physical ...
