Dark Matter Distribution in Nearby Galaxies [PDF]
Symposium - International Astronomical Union, 2004 We present results obtained from a study of the mass distribution of 24 galaxies observed using Fabry-Pérot techniques, as part of the GHASP survey (see Russeil et al., this meeting). For each galaxy, we combined high resolution Hα rotation curves derived from 2-D velocity fields, with low resolution HI data, in order to determine accurately the inner ...

Under the Firelight: Stellar Tracers of the Local Dark Matter Velocity Distribution in the Milky Way [PDF]
, 2018 The Gaia era opens new possibilities for discovering the remnants of disrupted satellite galaxies in the Solar neighborhood. If the population of local accreted stars is correlated with the dark matter sourced by the same mergers, one can then map the ...

Distribution of phantom dark matter in dwarf spheroidals [PDF]
Astronomy & 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.

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.

Shapley supercluster survey: mapping the dark matter distribution [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT We present a 23 deg2 weak gravitational lensing survey of the Shapley supercluster core and its surroundings using gri VST images as part of the Shapley Supercluster Survey (ShaSS). This study reveals the overall matter distribution over a region containing 11 clusters at z ∼ 0.048 that are all interconnected, as well as several

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 ...

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 ...
