Spatial Distribution of Intracluster Light versus Dark Matter in Horizon Run 5
The Astrophysical JournalOne intriguing approach for studying the dynamical evolution of galaxy clusters is to compare the spatial distributions among various components such as dark matter, member galaxies, gas, and intracluster light (ICL).

On the Spatial Distribution of Dark Matter Halos
The Astrophysical Journal, 1998 We study the spatial distribution of dark matter halos in the Universe in terms of their number density contrast, related to the underlying dark matter fluctuation via a non-local and non-linear bias random field. The description of the matter dynamics is simplified by adopting the `truncated' Zel'dovich approximation to obtain both analytical results ...

Radial dependence of the dark matter distribution in M33 [PDF]
Monthly Notices of the Royal Astronomical Society, 2017 The stellar and gaseous mass distributions, as well as the extended rotation curve in the nearby galaxy M33 are used to derive the radial distribution of dark matter density in the halo and to test cosmological models of galaxy formation and evolution. Two methods are examined to constrain dark mass density profiles.

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.

An excursion set model for the distribution of dark matter and dark matter haloes [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 A model of the gravitationally evolved dark matter distribution, in the Eulerian space, is developed. It is a simple extension of the excursion set model that is commonly used to estimate the mass function of collapsed dark matter haloes. In addition to describing the evolution of the dark matter itself, the model allows one to describe the evolution ...

The Distribution of Dark Matter in Spirals [PDF]
EAS Publications Series, 2006 In the past years a wealth of observations allowed to unravel the structural properties of the Dark Matter Halos around spirals. First, their rotation curves follow an Universal profile (URC) that can be described in terms of an exponential thin stellar disk and a dark halo with a constant density core, whose relative importance increases with galaxy ...

The distribution of inelastic dark matter in the Sun [PDF]
European Physical Journal C: Particles and Fields, 2018 If dark matter is composed of new particles, these may become captured after scattering with nuclei in the Sun, thermalize through additional scattering, and finally annihilate into neutrinos that can be detected on Earth.

How does dark matter affect compact star properties and high density constraints of strongly interacting matter [PDF]
EPJ Web of Conferences, 2022 We study the impact of asymmetric bosonic dark matter on neutron star properties, including possible changes of tidal deformability, maximum mass, radius, and matter distribution inside the star.
