Simulation budgeting for hybrid effective field theories
Alexa Bartlett, Joseph DeRose, Martin White
In this work, we forecast the number of, and requirements on, N-body simulations needed to train hybrid effective field theory (HEFT) emulators for a range of use cases, using a hy…
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…
The weak, the strong and the ugly -- A comparative analysis of interacting stepped dark radiation
Nils Schöneberg, Guillermo Franco Abellán, Théo Simon +3
Models which address both the Hubble and tensions with the same mechanism generically cause a pre-recombination suppression of the small scale matter power spectrum. Here we…
Dark Energy at early times and ACT: a larger Hubble constant without late-time priors
Vivian Poulin, Tristan L. Smith, Alexa Bartlett
In this paper we fit two models of Early Dark Energy (EDE) (an increase in the expansion rate before recombination) to the combination of Atacama Cosmology Telescope (ACT) measurem…
