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.

Dark matter distribution in the merging cluster Abell 2163 [PDF]
, 2012 The cluster Abell 2163 is a merging system of several subclusters with complex dynamics. It presents exceptional X-rays properties (high temperature and luminosity), suggesting that it is a very massive cluster. Recent 2D analysis of the gas distribution

Big Bang Synthesis of Nuclear Dark Matter [PDF]
, 2015 We investigate the physics of dark matter models featuring composite bound states carrying a large conserved dark "nucleon" number. The properties of sufficiently large dark nuclei may obey simple scaling laws, and we find that this scaling can determine

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 ...

THE DARK MATTER DISTRIBUTION IN A383: EVIDENCE FOR A SHALLOW DENSITY CUSP FROM IMPROVED LENSING, STELLAR KINEMATIC, AND X-RAY DATA [PDF]
, 2011 We extend our analyses of the dark matter (DM) distribution in relaxed clusters to the case of A383, a luminous X-ray cluster at z = 0.189 with a dominant central galaxy and numerous strongly lensed features.

Dark Matter distribution in the Milky Way: microlensing and dynamical constraints [PDF]
, 2011 nd that the most commonly discussed Dark Matter proles ( viz. Navarro-Frenk-White and Einasto) are consistent with microlensing and dynamical observations, while extreme adiabatically compressed proles are robustly ruled out.

Neutrino Constraints on the Dark Matter Total Annihilation Cross Section [PDF]
, 2007 In the indirect detection of dark matter through its annihilation products, the signals depend on the square of the dark matter density, making precise knowledge of the distribution of dark matter in the Universe critical for robust predictions.

Flat-Cored Dark Matter in Cuspy Clusters of Galaxies
, 2003 Sand, Treu, & Ellis (2002) have measured the central density profile of cluster MS2137-23 with gravitational lensing and velocity dispersion and removed the stellar contribution with a reasonable M/L.
