Saxion cosmology for thermalized gravitino dark matter

Journal of High Energy Physics, 2017
In all supersymmetric theories, gravitinos, with mass suppressed by the Planck scale, are an obvious candidate for dark matter; but if gravitinos ever reached thermal equilibrium, such dark matter is apparently either too abundant or too hot, and is ...

Superclustering with the Atacama Cosmology Telescope and Dark Energy Survey. II. Anisotropic Large-scale Coherence in Hot Gas, Galaxies, and Dark Matter

The Astrophysical Journal
Statistics that capture the directional dependence of the baryon distribution in the cosmic web enable unique tests of cosmology and astrophysical feedback.

Warm-plus-hot neutrino dark matter [PDF]

Physical Review D, 1995
We investigate a new hybrid-model universe containing two types of dark matter, one ``warm'' and the other ``hot.'' The hot component is an ordinary light neutrino with mass \ensuremath{\sim}25${\mathit{h}}^{2}$ eV while the warm component is a sterile neutrino with mass \ensuremath{\sim}700${\mathit{h}}^{2}$ eV.

Axions as hot and cold dark matter [PDF]

Journal of Cosmology and Astroparticle Physics, 2014
The presence of a hot dark matter component has been hinted at 3 sigma by a combination of the results from different cosmological observations. We examine a possibility that pseudo Nambu-Goldstone bosons account for both hot and cold dark matter components.

Hot-dark matter, cold dark matter and accelerating universe

, 2006
The Friedman equation is solved for a universe contains hotdark matter and cold dark matter. In this scenario, hot-dark matter drives an accelerating universe no cold dark matter.

Hot new early dark energy: Towards a unified dark sector of neutrinos, dark energy and dark matter

Physics Letters B, 2022
Hot new early dark energy describes a supercooled, first-order phase transition that takes place at sub-eV temperatures in the dark sector. It lowers the sound horizon, which provides a possible solution to the Hubble tension, and, at the same time, it ...

A model for mixed warm and hot right-handed neutrino dark matter

Journal of High Energy Physics, 2021
We discuss a model where a mixed warm and hot keV neutrino dark matter rises naturally. We arrange active and sterile neutrinos in the same SU(3) L multiplet, with the lightest sterile neutrino being dark matter.
