Observational evidence for self-interacting cold dark matter [PDF]
Physical Review Letters, 1999 Cosmological models with cold dark matter composed of weakly interacting particles predict overly dense cores in the centers of galaxies and clusters and an overly large number of halos within the Local Group compared to actual observations.

Dark matter effect on the weak deflection angle by black holes at the center of Milky Way and M87 galaxies [PDF]
European Physical Journal C: Particles and Fields, 2022 In this paper, we investigated the effect of dark matter on the weak deflection angle by black holes at the galactic center. We consider three known dark matter density profiles such as the Cold Dark Matter, Scalar Field Dark Matter, and the Universal ...

Axinos as Cold Dark Matter [PDF]
AIP Conference Proceedings, 2006 The connection of Dark Matter to our particle physics model is still one of the open cosmological questions. In these proceedings I will argue that axinos can be successful Cold Dark Matter candidates in models with Supersymmetry and the Peccei-Quinn solution of the strong CP problem.

Non-cold dark matter from primordial black hole evaporation [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Dark matter coupled solely gravitationally can be produced through the decay of primordial black holes in the early universe. If the dark matter is lighter than the initial black hole temperature, it could be warm enough to be subject to structure ...

Updated constraints on decaying cold dark matter [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 In this paper we update the constraints on the simple decaying cold dark matter (DCDM) model with dark radiation (DR) as decay product. We consider two different regimes of the lifetime, i.e.

Self-interacting dark matter implied by nano-Hertz gravitational waves [PDF]
Physical Review D, 2023 The self-interacting dark matter (SIDM) paradigm offers a potential solution to the small-scale structure problems faced by collisionless cold dark matter. This framework incorporates self-interactions among dark matter particles, typically mediated by a

Simulating mixed fuzzy and cold dark matter [PDF]
, 2020 The distinctive effects of fuzzy dark matter are most visible at non-linear galactic scales. We present the first simulations of mixed fuzzy and cold dark matter, obtained with an extended version of the Nyx code.

The Cusp–Core Problem in Gas-Poor Dwarf Spheroidal Galaxies
Galaxies, 2021 This review deals with the inconsistency of inner dark matter density profiles in dwarf galaxies, known as the cusp–core problem. In particular, we aim to focus on gas-poor dwarf galaxies.
