Les Houches Lectures on Indirect Detection of Dark Matter

open access: yesSciPost Physics Lecture Notes, 2022
These lectures, presented at the 2021 Les Houches Summer School on Dark Matter, provide an introduction to key methods and tools of indirect dark matter searches, as well as a status report on the field circa summer 2021.

How does dark matter affect compact star properties and high density constraints of strongly interacting matter [PDF]

open access: yesEPJ Web of Conferences, 2022
We study the impact of asymmetric bosonic dark matter on neutron star properties, including possible changes of tidal deformability, maximum mass, radius, and matter distribution inside the star.

The local dark matter distribution in self-interacting dark matter halos

open access: yesJournal 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

Distribution of phantom dark matter in dwarf spheroidals [PDF]

open access: yesAstronomy & Astrophysics, 2020
We derive the distribution of the phantom dark matter in the eight classical dwarf galaxies surrounding the Milky Way, under the assumption that modified Newtonian dynamics (MOND) is the correct theory of gravity. According to their observed shape, we model the dwarfs as axisymmetric systems, rather than spherical systems, as usually assumed.

Dark Matter direct detection of classical WIMPs

open access: yesSciPost 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.

Magellan/M2FS and MMT/Hectochelle Spectroscopy of Dwarf Galaxies and Faint Star Clusters within the Galactic Halo

open access: yesThe Astrophysical Journal Supplement Series, 2023
We present spectroscopic data for 16,369 stellar targets within and/or toward 38 dwarf spheroidal galaxies and faint star clusters within the Milky Way halo environment.

On the Spatial Distribution of Dark Matter Halos

open access: yesThe Astrophysical Journal, 1998
We study the spatial distribution of dark matter halos in the Universe in terms of their number density contrast, related to the underlying dark matter fluctuation via a non-local and non-linear bias random field. The description of the matter dynamics is simplified by adopting the `truncated' Zel'dovich approximation to obtain both analytical results ...

Indirect Evidence for Dark Matter Density Spikes around Stellar-mass Black Holes

open access: yesThe 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.

Clumps and streams in the local dark matter distribution [PDF]

open access: yesNature, 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.
