A new recipe for $$\Lambda $$ Λ CDM
European 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.

Assessment of Dark Matter Models Using Dark Matter Correlations across Dwarf Spheroidal Galaxies
Universe, 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 ...

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

, 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 ...

Strangeness, cosmological cold dark matter and dark energy [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2005 It is now believed that the universe is composed of a small amount of the normal luminous matter, a substantial amount of matter (Cold Dark Matter: CDM) which is non-luminous and a large amount of smooth energy (Dark Energy: DE). Both CDM and DE seem to require ideas beyond the standard model of particle interactions.

DUNE Prospect for Leptophobic Dark Matter
Advances 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
Frontiers 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 ...

Constraints on anharmonic corrections of fuzzy dark matter
Journal 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 ...
