Calculation of momentum distribution function of a non-thermal fermionic dark matter [PDF]

, 2016
The most widely studied scenario in dark matter phenomenology is the thermal WIMP scenario. Inspite of numerous efforts to detect WIMP, till now we have no direct evidence for it.

The Roman View of Strong Gravitational Lenses

The Astrophysical Journal
Galaxy–galaxy strong gravitational lenses can constrain dark matter models and the Lambda cold dark matter cosmological paradigm at subgalactic scales. Currently, there is a dearth of images of these rare systems with high signal-to-noise ratio (SNR) and

Dark matter, black holes, and gravitational waves

Nuclear Physics B
The formation and growth of black holes can strongly influence the distribution of dark matter around them. I discuss here the different types of dark matter overdensities around black holes, including dark matter cusps, spikes, mounds, crests, and ...

The distribution of inelastic dark matter in the Sun

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.

A simple analytical model for dark matter halo structure and adiabatic contraction

, 2006
A simple analytical model for describing inner parts of dark matter halo is considered. It is assumed that dark matter density is power-law. The model deals with dark matter distribution function in phase space of adiabatic invariants (radial action and ...

The dark matter environment of the Abell 901/902 supercluster: a weak lensing analysis of the HST STAGES survey [PDF]

, 2008
We present a high resolution dark matter reconstruction of the z=0.165 Abell 901/902 supercluster from a weak lensing analysis of the HST STAGES survey.

The universal rotation curve of spiral galaxies II: the dark matter distribution out to the virial radius [PDF]

, 2007
In the current ACDM cosmological scenario, N-body simulations provide us with a universal mass profile, and consequently a universal equilibrium circular velocity of the virialized objects, as galaxies.

8T- 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 Stellar Distribution in Ultrafaint Dwarf Galaxies Suggests Deviations from the Collisionless Cold Dark Matter Paradigm

The Astrophysical Journal Letters
Unraveling the nature of dark matter (DM) stands as a primary objective in modern physics. Here we present evidence suggesting deviations from the collisionless cold DM (CDM) paradigm.

Caustics, Cold Flows, and Annual Modulation

Advances in Astronomy, 2011
We discuss the formation of dark matter caustics, and their possible detection by future dark matter experiments. The annual modulation expected in the recoil rate measured by a dark matter detector is discussed.
