Degeneracy pressure of mass dimension one fermionic fields and the dark matter halo of galaxies

TL;DR

This paper proposes that mass dimension one fermionic fields, acting as dark matter, can explain galactic halos through degeneracy pressure, with specific particle masses fitting dwarf and large galaxy rotation data.

Contribution

It introduces a novel dark matter candidate based on mass dimension one fermionic fields and demonstrates its ability to explain galactic rotation curves.

Findings

Dwarf galaxy halos fit with particle mass 100-200 eV.

Milky Way rotation curve fits with particle mass around 23 eV.

Degeneracy pressure of these fields can account for dark matter effects.

Abstract

In this paper, the recently proposed mass dimension one fermionic field is supposed to be responsible for the dark matter halo around galactic nuclei, through the quantum degeneracy pressure effect of the field. It will be showed that the mass-ratio relation for dwarf galaxies can be well explained for a particle dark matter mass of about $100 - 200$eV. For a large galaxy, as Milky Way, the observational data for rotation curve can be well reproduced for a particle mass of about 23eV, with the addition of other substructures.
