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.

Effects of P-wave Annihilation on the Angular Power Spectrum of Extragalactic Gamma-rays from Dark Matter Annihilation [PDF]
, 2011 We present a formalism for estimating the angular power spectrum of extragalactic gamma-rays produced by dark matter annihilating with any general velocity-dependent cross section.

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.

Variational Distributions & Dark matter
, 2021 By analyzing the main equation of the 8T in universe packet representation the author expends the idea of "dark energy" an additional gravitational trace from a distinct manifold with isomorphic areas of extremum curvature which have different matter ...

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

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 ...

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 ...

Experimental identification of non-pointlike dark-matter candidates [PDF]
, 2002 We show that direct dark matter detection experiments can distinguish between pointlike and non-pointlike dark-matter candidates. The shape of the nuclear recoil energy spectrum from pointlike dark-matter particles, e.g., neutralinos, is determined by ...

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 ...
