The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
PROSPECT: A profile likelihood code for frequentist cosmological parameter inference
Emil Brinch Holm, Andreas Nygaard, Jeppe Dakin +2
Cosmological parameter inference has been dominated by the Bayesian approach for the past two decades, primarily due to its computational efficiency. However, the Bayesian approach…
Cutting corners: Hypersphere sampling as a new standard for cosmological emulators
Andreas Nygaard, Emil Brinch Holm, Steen Hannestad +1
Cosmological emulators of observables such as the Cosmic Microwave Background (CMB) spectra and matter power spectra commonly use training data sampled from a Latin hypercube. This…
Local clustering of relic neutrinos: Comparison of kinetic field theory and the Vlasov equation
Emil Brinch Holm, Stefan Zentarra, Isabel M. Oldengott
Gravitational clustering in our cosmic vicinity is expected to lead to an enhancement of the local density of relic neutrinos. We derive expressions for the neutrino density, using…
