Under the Firelight: Stellar Tracers of the Local Dark Matter Velocity Distribution in the Milky Way [PDF]

open access: yesAstrophysical Journal, 2018
The Gaia era opens new possibilities for discovering the remnants of disrupted satellite galaxies in the Solar neighborhood. If the population of local accreted stars is correlated with the dark matter sourced by the same mergers, one can then map the ...

Measurement of anisotropy of dark matter velocity distribution using directional detection

open access: yesEPJ Web of Conferences, 2018
Although the velocity distribution of dark matter is assumed to be generally isotropic, some studies have found that ~25% of the distribution can have anisotropic components.

Physical properties of dark matter in galaxy U11454

open access: yesPhysical Sciences and Technology, 2020
In this paper physical characteristics of dark matter distribution in the spiral galaxy U11454 is explored using only well-known cored density profiles in the literature such as the pseudo-isothermal, Burkert, Einasto, exponential sphere, Beta and ...

Dark Matter: A Primer [PDF]

open access: yesAdvances in Astronomy, 2011
Dark matter is one of the greatest unsolved mysteries in cosmology at the present time. About 80% of the Universe's gravitating matter is nonluminous, and its nature and distribution are for the most part unknown.

Effects on the local dark matter distribution due to the Large Magellanic Cloud [PDF]

open access: yes, 2021
We study the local dark matter distribution in two models for the Milky Way (MW)-Large Magellanic Cloud (LMC) interaction. The effect of the LMC on the local dark matter distribution is dependent on the evolution of the MW-LMC system, such that a static ...

Revisiting dark matter freeze-in and freeze-out through phase-space distribution [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2021
We revisit dark-matter production through freeze-in and freeze-out by solving the Boltzmann equations at the level of the phase-space distribution f(p,t).

Uncertainties in the Galactic Dark Matter distribution: An update [PDF]

open access: yes, 2020
We present here a quantitative, accurate estimate of the impact of uncertainties of astrophysical nature on the determination of the dark matter distribution within our Galaxy, the Milky Way.

Bayesian reconstruction of the Milky Way dark matter distribution [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2019
We develop a novel Bayesian methodology aimed at reliably and precisely inferring the distribution of dark matter within the Milky Way using rotation curve data.

Dependence of dark matter - electron scattering on the galactic dark matter velocity distribution [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2020
The rate of dark matter-electron scattering depends on the underlying velocity distribution of the dark matter halo. Importantly, dark matter-electron scattering is particularly sensitive to the high-velocity tail, which differs significantly amongst the

Dark matter spike around Bumblebee black holes [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2023
The effects of dark matter spike in the vicinity of the supermassive black hole, located at the center of M87 (the Virgo A galaxy), are investigated within the framework of the so-called Bumblebee Gravity.
