Dark Matter direct detection of classical WIMPs
SciPost Physics Lecture Notes, 2022 One of the highest priorities in particle physics today is the identification of the constituents of dark matter. This manuscript is a supplement to pedagogical lectures given at the 2021 Les Houches Summer School on Dark Matter.

The local dark matter distribution in self-interacting dark matter halos
Journal of Cosmology and Astroparticle Physics, 2023 Abstract We study the effects of dark matter self-interactions on the local dark matter distribution in selected Milky Way-like galaxies in the EAGLE hydrodynamical simulations. The simulations were run with two different self-interacting dark matter models, a constant and velocity-dependent self-interaction cross-section. We find that

Indirect Evidence for Dark Matter Density Spikes around Stellar-mass Black Holes
The Astrophysical Journal Letters, 2023 It has been suggested for a long time that dark matter would form a density spike around a black hole. However, no promising evidence has been observed so far to verify this theoretical suggestion.

A DERIVATION OF (HALF) THE DARK MATTER DISTRIBUTION FUNCTION [PDF]
The Astrophysical Journal, 2012 All dark matter structures appear to follow a set of universalities, such as phase-space density or velocity anisotropy profiles, however, the origin of these universalities remains a mystery. Any equilibrated dark matter structure can be fully described by two functions, namely the radial and the tangential velocity distribution functions (VDF), and ...

Clumps and streams in the local dark matter distribution [PDF]
Nature, 2008 In cold dark matter cosmological models, structures form and grow by merging of smaller units. Numerical simulations have shown that such merging is incomplete; the inner cores of halos survive and orbit as "subhalos" within their hosts. Here we report a simulation that resolves such substructure even in the very inner regions of the Galactic halo.

Probing dark matter with resonant dynamics of the Galactic bar
, 2022 This thesis provides a novel dynamical evidence for dark matter by measuring for the first time the deceleration of the Galactic bar. This spin-down of the bar requires the transfer of energy and angular momentum to dark matter by dynamical friction ...

Imprint of Pressure on Characteristic Dark Matter Profiles: The Case of ESO0140040
Galaxies, 2020 We investigate the dark matter distribution in the spiral galaxy ESO0140040, employing the most widely used density profiles: the pseudo-isothermal, exponential sphere, Burkert, Navarro-Frenk-White, Moore and Einasto profiles.

On the distribution of dark matter in galaxies: Quantum treatments [PDF]
Journal of the Korean Physical Society, 2014 The problem of modeling the distribution of dark matter in galaxies in terms of equilibrium configurations of collisionless self-gravitating quantum particles is considered. We first summarize the pioneering model of a Newtonian self-gravitating Fermi gas in thermodynamic equilibrium developed by Ruffini and Stella (1983), which is shown to be the ...
