Model of the Galaxy with Hot Dark Matter [PDF]

open access: yesOpen Astronomy, 2018
Abstract 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. The galaxy is divided into two regions. In the inner region, the baryonic matter predominates over the hot dark matter

Dark matter as a heavy thermal hot relic [PDF]

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 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 dark matter particle mass is many orders of magnitude heavier than the usual $\sim$ eV hot relic mass ...

Biodiversity and emerging infectious threats: the microbial dark matter of Southwest China. [PDF]

open access: yesFront Microbiol
Southwest 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 ...

Indirect detection of hot dark matter

open access: yesJournal of High Energy Physics
A bstract Cosmologically 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. For relics with masses in the eV range, their role in structure formation depends

Thermal production of cold “hot dark matter” around eV

open access: yesJournal of High Energy Physics, 2023
Abstract 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. Despite there are several observational hints from background lights suggesting a DM in this mass range, the hot ...

THE HOT DARK MATTER MODEL: FURTHER INVESTIGATION

open access: yesOdessa 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. Galaxies formed from the baryonic matter, and the hot dark matter appears in the galaxies later.

Interference with gravitational instability: Hot and fuzzy dark matter

open access: yesPhysical Review D
Wave or fuzzy dark matter produced with high momenta behaves in many ways like hot particle dark matter while also possessing seemingly different phenomenology due to wave interference. We develop wave perturbation theory to show that white noise density fluctuations generated by the interference of high-momenta waves are gravitationally unstable in ...
