Dark matter annihilation in the halo of the Milky Way [PDF]
Monthly Notices of the Royal Astronomical Society, 2003 If the dark matter in the Universe is made of weakly self-interacting particles, they may self-annihilate and emit gamma-rays. We use high resolution numerical simulations to estimate directly the annihilation flux from the central regions of the Milky Way and from dark matter substructures in its halo.

The Dark Matter halo of the Milky Way, AD 2013 [PDF]
Journal of Cosmology and Astroparticle Physics, 2013 We derive the mass model of the Milky Way (MW) using a cored dark matter (DM) halo profile and recent data. The method used consists in fitting a spherically symmetric model of the Galaxy with a Burkert DM halo profile to available data: MW terminal velocities in the region inside the solar circle, circular velocity as recently estimated from maser ...

Is the dark matter halo of the Milky Way flattened? [PDF]
Astronomy & Astrophysics, 2006 We performed an extended analysis of the parameter space for the interaction of the Magellanic System with the Milky Way (MW). The varied parameters cover the phase space parameters, the masses, the structure, and the orientation of both Magellanic Clouds, as well as the flattening of the dark matter halo of the MW. The analysis was done by a specially

Using frequency maps to explore the distribution function of the Milky Way stellar halo
EPJ Web of Conferences, 2012 Resolved surveys of the Milky Way's stellar halo can obtain all 6 phase space coordinates of tens of thousands of individual stars, making it possible to compute their 3-dimensional orbits.

Machine Learning the Dark Matter Halo Mass of Milky Way-Like Systems [PDF]
The Open Journal of AstrophysicsDespite the Milky Way's proximity to us, our knowledge of its dark matter halo is fairly limited, and there is still considerable uncertainty in its halo mass.

Dark matter decay in the Milky Way halo [PDF]
Dark matter may be detected in X-ray decay, including from the decay of the dark matter particles that make up the Milky Way (MW) halo. We use a range of density profiles to compute X-ray line intensity profiles, with a focus on the resonantly produced sterile neutrino dark matter candidate.

The Stellar Halo of the Galaxy is Tilted and Doubly Broken
The Astronomical Journal, 2022 Modern Galactic surveys have revealed an ancient merger that dominates the stellar halo of our galaxy (Gaia–Sausage–Enceladus, GSE). Using chemical abundances and kinematics from the H3 Survey, we identify 5559 halo stars from this merger in the radial ...

Probing the Milky Way’s Dark Matter Halo for the 3.5 keV Line [PDF]
The Astrophysical Journal, 2020 Abstract We present a comprehensive search for the 3.5 keV line using ∼51 Ms of archival Chandra observations peering through the Milky Way’s dark matter halo from across the entirety of the sky, gathered via the Chandra Source Catalog Release 2.0. We consider the data’s radial distribution, organizing observations into four data subsets
