Cosmological Simulation for Fuzzy Dark Matter Model
Frontiers in Astronomy and Space Sciences, 2019 Fuzzy Dark Matter (FDM), motivated by string theory, has recently become a hot candidate for dark matter. The rest mass of FDM is believed to be ~10−22eV and the corresponding de-Broglie wave length is ~1kpc. Therefore, the quantum effect of FDM plays an

Neutrinos as Hot or Warm Dark Matter [PDF]
, 2011 Both active and sterile sub-eV neutrinos can serve for hot dark matter (DM). On the other hand, keV sterile neutrinos could be a good candidate for warm DM. The beta-decaying (e.g., H-3 and Ru-106) and EC-decaying (e.g., Ho-163) nuclei are considered as the most promising targets to capture those extremely low energy neutrinos and antineutrinos ...

The Open Journal of Astrophysics, 2021 We apply the squeezed state formalism to scalar field dark matter (e.g. axion) perturbations generated during inflation. As for the inflationary perturbations, the scalar field state becomes highly squeezed as modes exit the horizon. For as long as $H>m_\

The alignment and shape of dark matter, stellar, and hot gas distributions in the EAGLE and cosmo-OWLS simulations [PDF]
, 2015 We report the alignment and shape of dark matter, stellar, and hot gas distributions in the EAGLE (Evolution and Assembly of GaLaxies and their Environments) and cosmo-OWLS(Over- Whelmingly Large Simulations) simulations.

Cannibalism hinders growth: Cannibal Dark Matter and the S8 tension [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 Many models of dark matter have been proposed in attempt to ease the S8 tension between weak lensing and CMB experiments. One such exciting possibility is cannibalistic dark matter (CanDM), which has exothermal number-changing interactions allowing it to

Cosmological Effects of Quantum Vacuum Condensates
Galaxies, 2017 In quantum field theory, many phenomena are characterized by a condensed structure of their vacua. Such a structure is responsible of a non trivial vacuum energy. Here we analyze disparate systems and we show that the thermal vacuum state for hot plasmas,
