Lepton Flavour Asymmetries and the Mass Spectrum of Primordial Black Holes
Dietrich Bodeker, Florian Kuhnel, Isabel M. Oldengott +1
We study the influence of lepton flavour asymmetries on the formation and the mass spectrum of primordial black holes. We estimate the detectability of their mergers with LIGO/Virg…
Invisible neutrino decay in precision cosmology
Gabriela Barenboim, Joe Zhiyu Chen, Steen Hannestad +3
We revisit the topic of invisible neutrino decay in the precision cosmological context, via a first-principles approach to understanding the cosmic microwave background and large-s…
Inflation meets neutrinos
Gabriela Barenboim, Peter B. Denton, Isabel M. Oldengott
Constraints on inflationary models typically assume only the standard models of cosmology and particle physics. By extending the neutrino sector to include a new interaction with a…
How to relax the cosmological neutrino mass bound
Isabel M. Oldengott, Gabriela Barenboim, Sarah Kahlen +2
We study the impact of non-standard momentum distributions of cosmic neutrinos on the anisotropy spectrum of the cosmic microwave background and the matter power spectrum of the la…
Cosmic QCD Epoch at Nonvanishing Lepton Asymmetry
Mandy M. Wygas, Isabel M. Oldengott, Dietrich Bodeker +1
We investigate how a lepton asymmetry impacts the cosmic trajectory in the QCD phase diagram. We study the evolution of chemical potentials during the QCD epoch of the early Univer…
Interacting neutrinos in cosmology: exact description and constraints
Isabel M. Oldengott, Thomas Tram, Cornelius Rampf +1
We consider the impact of neutrino self-interactions described by an effective four-fermion coupling on cosmological observations. Implementing the exact Boltzmann hierarchy for in…
