A new recipe for $$\Lambda $$ Λ CDM

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
It is well known that a canonical scalar field is able to describe either dark matter or dark energy but not both. We demonstrate that a non-canonical scalar field can describe both dark matter and dark energy within a unified setting.

DUNE Prospect for Leptophobic Dark Matter

open access: yesAdvances in High Energy Physics, 2020
Highly energetic proton/electron beam fixed-target experiments extend an opportunity to probe the sub-GeV dark matter and associated interactions. In this work, we have explored the sensitivity of DUNE (Deep Underground Neutrino Experiment) for sub-GeV ...

To Observe, or Not to Observe, Quantum-Coherent Dark Matter in the Milky Way, That is a Question

open access: yesFrontiers in Astronomy and Space Sciences, 2021
In recent years, Bose-Einstein-condensed dark matter (BEC-DM) has become a popular alternative to standard, collisionless cold dark matter (CDM). This BEC-DM -also called scalar field dark matter (SFDM)- can suppress structure formation and thereby ...

Phenomenology of Dark Matter via a Bimetric Extension of General Relativity [PDF]

open access: yes, 2015
We propose a relativistic model of dark matter reproducing at once the concordance cosmological model $\Lambda$-Cold-Dark-Matter ($\Lambda$-CDM) at cosmological scales, and the phenomenology of the modified Newtonian dynamics (MOND) at galactic scales ...

Constraints on anharmonic corrections of fuzzy dark matter

open access: yesJournal of High Energy Physics, 2018
The cold dark matter (CDM) scenario has proved successful in cosmology. However, we lack a fundamental understanding of its microscopic nature. Moreover, the apparent disagreement between CDM predictions and subgalactic-structure observations has ...

Dark Matter Caustics [PDF]

open access: yes, 2008
Caustics are a generic feature of the nonlinear growth of structure in the dark matter distribution. If the dark matter were absolutely cold, its mass density would diverge at caustics, and the integrated annihilation probability would also diverge for ...

Assessment of Dark Matter Models Using Dark Matter Correlations across Dwarf Spheroidal Galaxies

open access: yesUniverse, 2022
The predicted size of dark matter substructures in kilo-parsec scales is model-dependent. Therefore, if the correlations between dark matter mass densities as a function of the distances between them are measured via observations, we can scrutinize dark ...

Observational evidence for self-interacting cold dark matter [PDF]

open access: yes, 2000
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.
