The spectrum of constraints from DESI and CMB data
Evan McDonough, Elisa G. M. Ferreira
We present the spectrum of constraints from current CMB data (Planck, ACT, SPT-3G) combined with DESI BAO data, and highlight the interplay of with the optical depth to…

Cold and fuzzy dark sector
Christian Capanelli, Elisa G. M. Ferreira, Evan McDonough
We introduce the Fuzzy Dark Sector (FDS) scenario as a rich, interacting system and candidate for dark matter. This serves as a natural extension of the single-component, non-inter…

The BAO-CMB Tension and Implications for Inflation
Elisa G. M. Ferreira, Evan McDonough, Lennart Balkenhol +3
The scalar spectral index is a powerful test of inflationary models. The tightest constraint on to date derives from the combination of cosmic microwave background (CMB…
