Weighing the Local Interstellar Medium using Gamma Rays and Dust
Axel Widmark, Michael Korsmeier, Tim Linden
Cold gas forms a significant mass fraction of the Milky Way disk, but is its most uncertain baryonic component. The density and distribution of cold gas is of critical importance f…
Mapping Milky Way disk perturbations in stellar number density and vertical velocity using Gaia DR3
Axel Widmark, Lawrence M. Widrow, Aneesh Naik
We have mapped the number density and mean vertical velocity of the Milky Way's stellar disk out to roughly two kiloparsecs from the Sun using Gaia Data Release 3 (DR3) and complem…
The missing radial velocities of Gaia: blind predictions for DR3
Aneesh Naik, Axel Widmark
While Gaia has observed the phase space coordinates of over a billion stars in the Galaxy, in the overwhelming majority of cases it has only obtained five of the six coordinates, t…
Snowmass2021 Cosmic Frontier White Paper: Dark Matter Physics from Halo Measurements
Keith Bechtol, Simon Birrer, Francis-Yan Cyr-Racine +41
The non-linear process of cosmic structure formation produces gravitationally bound overdensities of dark matter known as halos. The abundances, density profiles, ellipticities, an…
Estimating the local dark matter density in a non-axisymmetric wobbling disc
S. Sivertsson, J. I. Read, H. Silverwood +6
The density of dark matter near the Sun is important for experiments hunting for dark matter particles in the laboratory, and for constraining the local shape of the Milky Way's da…
Weighing the Galactic disk using phase-space spirals IV. Tests on a three-dimensional galaxy simulation
Axel Widmark, Jason A. S. Hunt, Chervin F. P. Laporte +1
In this fourth article on weighing the Galactic disk using the shape of the phase-space spiral, we have tested our method on a billion particle three-dimensional N-body simulation,…
