Extending the standard model with three right-handed neutrinos and a simple QCD axion sector can account for neutrino oscillations, dark matter and baryon asymmetry; at the same time, it solves the strong CP problem, stabilizes the electroweak vacuum and can implement critical Higgs inflation (satisfying all current observational bounds). We perform here a general analysis of dark matter (DM) in such a model, which we call the aνMSM. Although critical Higgs inflation features a (quasi… Expand

Thermal axions with multi-eV masses are possible in low-reheating scenarios
We revise cosmological mass bounds on hadronic axions in low-reheating cosmological scenarios, with a reheating temperature T RH ≤ 100 MeV, in light of the latest cosmological observations. In thisExpand

CPT-Symmetric Universe.
TLDR
The Universe after the big bang is the CPT image of the Universe before it, both classically and quantum mechanically, providing a new interpretation of the cosmological baryon asymmetry, as well as a remarkably economical explanation for thecosmological dark matter. Expand
New constraints on sterile neutrino dark matter from NuSTAR M31 observations
We use a combined 1.2 Ms of $NuSTAR$ observations of M31 to search for X-ray lines from sterile neutrino dark matter decay. For the first time in a $NuSTAR$ analysis, we consistently take intoExpand
Lepton asymmetry and primordial nucleosynthesis in the era of precision cosmology
We calculate and display the primordial light-element abundances as a function of a neutrino degeneracy parameter {xi} common to all flavors. It is the only unknown parameter characterizing theExpand
Critical Higgs inflation in a viable motivated model
An extension of the Standard Model with three right-handed neutrinos and a simple invisible axion model can account for all experimentally confirmed signals of new physics (neutrino oscillations,Expand

Sterile neutrino dark matter from generalized CPT -symmetric early-Universe cosmologies
We generalize gravitational particle production in a radiation-dominated CPT -symmetric universe to non-standard, but also CPT -symmetric early universe cosmologies. We calculate the mass of aExpand
2020 global reassessment of the neutrino oscillation picture
We present an updated global fit of neutrino oscillation data in the simplest three-neutrino framework. In the present study we include up-to-date analyses from a number of experiments. Namely, weExpand
Constraints on Primordial Black Holes
We update the constraints on the fraction of the Universe going into primordial black holes (PBHs) over the mass range $10^{-5}$--$10^{50}$ g. Those smaller than $\sim 10^{15}$ g would haveExpand
Dimensional transmutation in gravity and cosmology
We review (and extend) the analysis of general theories of all interactions (gravity included) where the mass scales are due to dimensional transmutation. Quantum consistency requires the presence ofExpand
Freeze-in generation of lepton asymmetries after baryogenesis in the $\nu$MSM
