Search for dark matter annihilation in the Milky Way halo
Physical Review D, 2018 The Milky Way halo is the brightest source of dark matter annihilation on the sky. Indeed, the potential strength of the Galactic dark matter signal can supersede that expected from dwarf galaxies and galaxy groups even in regions away from the Inner Galaxy.

Endothermic self-interacting dark matter in Milky Way-like dark matter haloes
Monthly Notices of the Royal Astronomical Society, 2023 ABSTRACT Self-interacting dark matter (SIDM) offers the potential to mitigate some of the discrepancies between simulated cold dark matter (CDM) and observed galactic properties. We introduce a physically motivated SIDM model to understand the effects of self interactions on the properties of Milky Way and dwarf galaxy sized haloes. This

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 ...

Dark matter halo cores and the tidal survival of Milky Way satellites
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT The cuspy central density profiles of cold dark matter (CDM) haloes make them highly resilient to disruption by tides. Self-interactions between dark matter particles, or the cycling of baryons, may result in the formation of a constant-density core that would make haloes more susceptible to tidal disruption.

The impact of inelastic self-interacting dark matter on the dark matter structure of a Milky Way halo [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 Abstract We study the effects of inelastic dark matter self-interactions on the internal structure of a simulated Milky Way (MW)-size halo. Self-interacting dark matter (SIDM) is an alternative to collisionless cold dark matter (CDM) which offers a unique solution to the problems encountered with CDM on sub-galactic scales.

Streams and the Milky Way dark matter halo
Proceedings of the International Astronomical Union, 2019AbstractWe describe an algorithm that can fit the properties of the dwarf galaxy progenitor of a tidal stream, given the properties of that stream. We show that under ideal conditions (the Milky Way potential, the orbit of the dwarf galaxy progenitor, and the functional form of the dwarf galaxy progenitor are known exactly), the density and angular ...

Constraints on the parameters of radiatively decaying dark matter from the dark matter halos of the Milky Way and Ursa Minor [PDF]
Astronomy and Astrophysics, 2007 We improve the earlier restrictions on parameters of the dark matter (DM) in the form of a sterile neutrino. The results were obtained from non-observing the DM decay line in the X-ray spectrum of the Milky Way (using the recent XMM-Newton PN blank sky data).
