Alleviating cosmological tensions with a hybrid dark sector
Elsa M. Teixeira, Gaspard Poulot, Carsten van de Bruck +2
We investigate a cosmological model inspired by hybrid inflation, where two scalar fields representing dark energy (DE) and dark matter (DM) interact through a coupling that is pro…
On the implications of the `cosmic calibration tension' beyond and the synergy between early- and late-time new physics
Vivian Poulin, Tristan L. Smith, Rodrigo Calderón +1
The `cosmic calibration tension' is a discrepancy between the cosmological distance ladder built from baryonic acoustic oscillations (BAO) calibrated by the Planck/CDM so…
Procoli: Profiles of cosmological likelihoods
Tanvi Karwal, Yashvi Patel, Alexa Bartlett +3
Frequentist profile likelihoods have seen a resurgence in cosmology, offering an alternative to Bayesian methods as they can circumvent the impact of prior-volume effects. This pap…
Improved Planck constraints on axion-like early dark energy as a resolution of the Hubble tension
George Efstathiou, Erik Rosenberg, Vivian Poulin
Axion-like early dark energy (EDE) as an extension to CDM has been proposed as a possible solution to the 'Hubble tension'. We revisit this model using a new cosmic microwave ba…
Bayesian and frequentist investigation of prior effects in EFTofLSS analyses of full-shape BOSS and eBOSS data
Emil Brinch Holm, Laura Herold, Théo Simon +4
Previous studies based on Bayesian methods have shown that the constraints on cosmological parameters from the Baryonic Oscillation Spectroscopic Survey (BOSS) full-shape data usin…
Current small-scale CMB constraints to axion-like early dark energy
Tristan L. Smith, Vivian Poulin
The SPT-3G 2018 TT/TE/EE cosmic microwave background (CMB) data set (temperature and polarization) is used to place constraints on an axion-like model of early dark energy (EDE). T…
