Calculating Bayesian evidence for inflationary models using CONNECT

Camilla T. G. Sørensen, Steen Hannestad, Andreas Nygaard +1

Bayesian evidence is a standard tool used for comparing the ability of different models to fit available data and is used extensively in cosmology. However, since the evidence calc…

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…

Circular reasoning: Solving the Hubble tension with a non-π value of π

Jonas El Gammal, Sven Günther, Emil Brinch Holm +1

Recently, cosmology has seen a surge in alternative models that purport to solve the discrepancy between the values of the Hubble constant H0​ as measured by cosmological microwa…
