We revisit cosmological constraints on the sum of the neutrino masses Σ m ν from a
combination of full-shape BOSS galaxy clustering [P (k)] data and measurements of the …

We explore the interplay between light primordial black holes (PBH) and high-scale
baryogenesis, with a particular emphasis on leptogenesis. We first review a generic …

We present the first comprehensive discussion of constraints on the cosmic neutrino
background (CνB) overdensity, including theoretical, experimental and cosmological limits …

We review the distortions of spectra of relic neutrinos due to the interactions with electrons,
positrons, and neutrinos in the early universe. We solve integro-differential kinetic equations …

The existence of a cosmic neutrino background has been inferred indirectly from
cosmological surveys through its effect on the linear-theory evolution of primordial density …

We present a solution of the Schrödinger-Poisson system based on the WKB ansatz for the
wave function. In this way we obtain a description of a gravitationally bound clump of axion …

We argue that the reflection of relic neutrinos from the surface of the Earth results in a
significant local ν-ν¯ asymmetry, far exceeding the expected primordial lepton asymmetry …

Gravitational potentials of the Milky Way and extragalactic structures can influence the
propagation of the cosmic neutrino background (CNB). Of particular interest to future CNB …

Dark radiation (DR) is generally predicted in new physics scenarios that address
fundamental puzzles of the Standard Model or tensions in the cosmological data …

We investigate a consistent scenario of time-varying neutrino masses, and discuss its impact
on cosmology, beta decay, and neutrino oscillation experiments. Such time-varying masses …
