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 ...

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 ...

The twisted dark matter halo of the Milky Way [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We analyse systems analogous to the Milky Way (MW) in the eagle cosmological hydrodynamics simulation in order to deduce the likely structure of the MW’s dark matter (DM) halo. We identify MW mass haloes in the simulation whose satellite galaxies have similar kinematics and spatial distribution to those of the bright satellites ...

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

A first estimate of the Milky Way dark matter halo spin [PDF]
Astronomy & Astrophysics, 2021 The spin, or normalized angular momentumλ, of dark matter halos in cosmological simulations follows a log normal distribution and has little correlation with galaxy observables such as stellar masses or sizes. There is currently no way to infer theλparameter of individual halos hosting observed galaxies.

The Milky Way’s halo and subhaloes in self-interacting dark matter [PDF]
Monthly Notices of the Royal Astronomical Society, 2019 ABSTRACT We perform high-resolution simulations of an MW-like galaxy in a self-interacting cold dark matter model with elastic cross-section over mass of $1~\rm cm^2\, g^{-1}$ (SIDM) and compare to a model without self-interactions (CDM).

DISPERSAL OF TIDAL DEBRIS IN A MILKY-WAY-SIZED DARK MATTER HALO [PDF]
The Astrophysical Journal, 2016 ABSTRACT We simulate the tidal disruption of a collisionless N-body globular star cluster in a total of 300 different orbits selected to have galactocentric radii between 10 and 30 kpc in four dark matter halos: (a) a spherical halo with no subhalos, (b) a spherical halo with subhalos, (c) a realistic halo with no subhalos, and (d) a ...
