Estimating Dark Matter Distributions
The Astrophysical Journal, 2005 Thanks to instrumental advances, new, very large kinematic datasets for nearby dwarf spheroidal (dSph) galaxies are on the horizon. A key aim of these datasets is to help determine the distribution of dark matter in these galaxies. Past analyses have generally relied on specific dynamical models or highly restrictive dynamical assumptions.

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.

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 ...

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 ...
