Dark matter induced Brownian motion

European Physical Journal C: Particles and Fields, 2020
We discuss a novel approach for directional, light dark matter searches inspired by the high precision position measurements achieved in gravitational wave detectors.

The Distribution of Satellite Galaxies in the IllustrisTNG100 Simulation

The Astrophysical Journal, 2022
We investigate the spatial distribution of the satellites of isolated host galaxies in the IllustrisTNG100 simulation. In agreement with a previous, similar analysis of the Illustris-1 simulation, the satellites are typically poor tracers of the mean ...

Stationar spherical-symmetric configuration of dark matter

Physical Sciences and Technology, 2021
The article is devoted to the consideration of a model problem, where mass flow of dark matter which take as only gravitational interacting spherical continuous medium without pressure and with radial opposite motion with equilibrium ascending and ...

The inner dark matter distribution of the Cosmic Horseshoe (J1148+1930) with gravitational lensing and dynamics

, 2019
We present a detailed analysis of the inner mass structure of the Cosmic Horseshoe (J1148+1930) strong gravitational lens system observed with the Hubble Space Telescope (HST) Wide Field Camera 3 (WFC3). In addition to the spectacular Einstein ring, this

Getting the astrophysics and particle physics of dark matter out of next-generation direct detection experiments [PDF]

, 2010
The next decade will bring massive new data sets from experiments of the direct detection of weakly interacting massive particle (WIMP) dark matter. The primary goal of these experiments is to identify and characterize the dark-matter particle species ...

Physical properties of dark matter in galaxy U11454

Physical 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 ...

A simple analytical model for dark matter halo structure and adiabatic contraction

, 2006
A simple analytical model for describing inner parts of dark matter halo is considered. It is assumed that dark matter density is power-law. The model deals with dark matter distribution function in phase space of adiabatic invariants (radial action and ...

The distribution of inelastic dark matter in the Sun

European Physical Journal C: Particles and Fields, 2018
If dark matter is composed of new particles, these may become captured after scattering with nuclei in the Sun, thermalize through additional scattering, and finally annihilate into neutrinos that can be detected on Earth.

Dark matter distribution in superthin galaxies

Monthly Notices of the Royal Astronomical Society, 2020
ABSTRACT This paper presents a new method of calculating dark matter density profiles for superthin axial symmetric galaxies without a bulge. This method is based on a simple physical model, which includes an infinitely thin galactic disc immersed in a spherically symmetric halo of dark matter. To obtain the desired distribution density,
