First Direct-Detection Results on Sub-GeV Dark Matter Using the SENSEI Detector at SNOLAB.
Physical Review Letters, 2023We present the first results from a dark matter search using six Skipper-CCDs in the SENSEI detector operating at SNOLAB. We employ a bias-mitigation technique of hiding approximately 46% of our total data and aggressively mask images to remove ...

The Cold + Hot Dark Matter (CHDM) model appears to require about 5 eV of neutrino mass in order to produce early enough galaxy formation. Recent experimental data suggests that this neutrino mass may be divided between two species of neutrinos, each with mass of about 2.4 eV.

Evaporating Primordial Black Holes, the String Axiverse, and Hot Dark Radiation.
Physical Review Letters, 2021The search for primordial black holes (PBHs) with masses M≪M_{⊙} is motivated by natural early-Universe production mechanisms and that PBHs can be dark matter.

Axion hot dark matter bound, reliably
2021We show that the commonly adopted hot dark matter (HDM) bound on the axion mass $m_a \lesssim$ 1 eV is not reliable, since it is obtained by extrapolating the chiral expansion in a region where the effective field theory breaks down. This is explicitly shown via the calculation of the axion-pion thermalization rate at the next-to-leading order in ...

A Little Hot Dark Matter Matters
Science, 1998Astronomers believe that a large part of the mass in the universe is "dark." But what is the nature of this unseen mass? In his research commentary, Primack discusses results reported in the same issue by Gawiser and Silk in which several models of dark matter were examined.

Light from darkness: history of a hot dark sector
Journal of Cosmology and Astroparticle PhysicsWe study a scenario in which the expansion of the Early Universe is driven by a hot hidden sector (HS) with an initial temperature T' that is significantly higher than that of the visible sector (VS), T' ≫ T.

Abstract Direct observations favor a low-mass-density universe, but a critical density universe with a neutrino component of dark matter provides the best model for explaining the observed structure of the universe over more than three orders of magnitude in distance scale.
