Sterile neutrino hot, warm, and cold dark matter [PDF]
Physical Review D, 2001 We calculate the incoherent resonant and non-resonant scattering production of sterile neutrinos in the early universe. We find ranges of sterile neutrino masses, vacuum mixing angles, and initial lepton numbers which allow these species to constitute viable hot, warm, and cold dark matter (HDM, WDM, CDM) candidates which meet observational constraints.

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,

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 ...

Axionic hot dark matter in the hadronic axion window [PDF]
Physics Letters B, 1998 12 pages, 1 figure, LaTeX2e, epsf.sty. Discussions on Moriyama's proposal to detect solar axions without relying on axion-photon-photon coupling and Haxton-Lee bound on axion-nucleon coupling are added.

Physics Letters B, 2014 We propose an ultraviolet complete theory for cold dark matter (CDM) and sterile neutrinos that can accommodate both cosmological data and neutrino oscillation experiments within 1σ level.

TeV Scale Theory for Cold and Hot Dark Matter [PDF]
Physical Review Letters, 1994 We show that an extension of the minimal supersymmetric standard model where neutrino mass arises from the spontaneous breakdown of global [ital B][minus][ital L] symmetry, can provide a scenario for both cold (CDM) and hot dark matter (HDM) where (i) both the CDM (which in our case is the superpartner of the Majoron) and the HDM (which is the massive ...

Neutrino interactions in the late universe
Journal of High Energy Physics, 2021 The cosmic neutrino background is both a dramatic prediction of the hot Big Bang and a compelling target for current and future observations. The impact of relativistic neutrinos in the early universe has been observed at high significance in a number of

Peripheral lysosomes recruit PLEKHG3 to focal adhesions and restrain protrusion dynamics
FEBS Letters, EarlyView.Proximity‐dependent labeling at the LAMTOR complex revealed the Rho GEF PLEKHG3 as a lysosome‐proximal protein directing the study toward the influence of lysosome positioning on actin dynamics and cell motility. We show that PLEKHG3 colocalizes with lysosomes at focal adhesion sites and observe that forced peripheral dispersion of lysosomes hinders ...
