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…
Minihalos as probes of the inflationary spectrum: accurate boost factor calculation and new CMB constraints
Guillermo Franco Abellán, Gaétan Facchinetti
Although the spectrum of primordial fluctuations has been accurately measured on scales above , only upper limits exist on smaller scales. In this study, we inve…
Hints of Early Dark Energy in Planck, SPT, and ACT data: new physics or systematics?
Tristan L. Smith, Matteo Lucca, Vivian Poulin +5
We investigate constraints on early dark energy (EDE) using ACT DR4, SPT-3G 2018, Planck polarization, and restricted Planck temperature data (at ), finding a pref…
Linear cosmological constraints on 2-body decaying dark matter scenarios and the tension
Guillermo Franco Abellán, Riccardo Murgia, Vivian Poulin
The ' tension' is a longstanding discrepancy between the cosmic microwave background (CMB) and weak gravitational lensing determination of the amplitude of matter fluctuations…
