Model of the Galaxy with Hot Dark Matter [PDF]
Open Astronomy, 2018 The model of the galaxy is considered as a structure of the baryonic matter embedded into the hot dark matter. The dark matter is supposed to come into being from the decaying matter after the epoch of structure formation.

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 ...

Dark matter as a heavy thermal hot relic [PDF]
Physics Letters B, 2020 If, during the early Universe epoch, the dark matter particle thermalizes in a hidden sector which does not thermalize with the Standard Model thermal bath, its relativistic thermal decoupling can easily lead to the observed relic density, even if the ...

Indirect detection of hot dark matter
Journal of High Energy PhysicsCosmologically stable, light particles that came into thermal contact with the Standard Model in the early universe may persist today as a form of hot dark matter.

Biodiversity and emerging infectious threats: the microbial dark matter of Southwest China [PDF]
Frontiers in MicrobiologySouthwest China is a global biodiversity hotspot, and its complex and diverse ecosystems harbor vast amounts of “microbial dark matter.” This paper systematically examines the distribution characteristics of microbial dark matter in hosts such as ...

Thermal production of cold “hot dark matter” around eV
Journal of High Energy Physics, 2023 A very simple production mechanism of feebly interacting dark matter (DM) that rarely annihilates is thermal production, which predicts the DM mass around eV. This has been widely known as the hot DM scenario.

THE HOT DARK MATTER MODEL: FURTHER INVESTIGATION
Odessa Astronomical Publications, 2020 e outer region with the dominant hot dark matter (the parabolic orbit of the test particle). It was assumed that the hot dark matter consists of hypothetical Planck neutrinos arising in the decay of the protons at the Planck scale.

Interacting hot dark matter [PDF]
Physical Review D, 1997 We discuss the viability of a light particle ($\sim 30$ eV neutrino) with strong self-interactions as a dark matter candidate. The interaction prevents the neutrinos from free-streaming during the radiation dominated regime so galaxy sized density perturbations can survive. Smaller scale perturbations are damped due to neutrino diffusion.

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.

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.
