The Story of Dark Matter [PDF]
, 2020 Several astronomical observations concerning the structure of galaxies, the rotation of stars in spiral galaxies, the motions of galaxies within a cluster of galaxies, and so on, cannot be understood in terms of Newton’s universal law of gravitation ...

Dark Matter in Disequilibrium: The Local Velocity Distribution from SDSS-Gaia [PDF]
, 2018 We use the distribution of accreted stars in SDSS-Gaia DR2 to demonstrate that the local dark matter halo may not be in equilibrium and that a non-trivial fraction is in substructure.

On the dark matter distribution in the Milky Way
, 2016 The distribution of dark matter in the Milky Way is a crucial input for ongoing studies in cosmology, astrophysics and particle physics. This motivates the effort over the next years to improve our mapping of dark matter, which has indeed become a top ...

The clustering of massive Primordial Black Holes as Dark Matter: measuring their mass distribution with Advanced LIGO [PDF]
, 2016 The recent detection by Advanced LIGO of gravitational waves (GW) from the merging of a binary black hole system sets new limits on the merging rates of massive primordial black holes (PBH) that could be a significant fraction or even the totality of the

Stellar mass map and dark matter distribution in M 31 [PDF]
, 2012 Aims. Stellar mass distribution in the Andromeda galaxy (M 31) is estimated using optical and near-infrared imaging data. Combining the derived stellar mass model with various kinematical data, properties of the dark matter (DM) halo of the galaxy are ...

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.

The metal-poor stellar halo in RAVE-TGAS and its implications for the velocity distribution of dark matter [PDF]
, 2017 The local velocity distribution of dark matter plays an integral role in interpreting the results from direct detection experiments. We previously showed that metal-poor halo stars serve as excellent tracers of the virialized dark matter velocity ...

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

The internal structure of Cold Dark Matter Haloes [PDF]
, 2010 Currently favoured cosmological models for structure formation of the Universe assume that a large fraction of the mass of the Universe is 'dark'. The evidence for dark matter comes from observations of its gravitational influence.

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.
