Constraints on unimodular diffusion models with latest observables
Jesús ChavarrÃa, Sebastien Fromenteau, Daniel Sudarsky +1
Cosmological models incorporating a time-dependent equation of state have recently been explored \cite{DESI:2025fii}, showing a preference for a dynamical dark energy component. In…

Constraining the phase shift of relativistic species in DESI BAOs
Abbé M. Whitford, Hugo Rivera-Morales, Cullan Howlett +36
In the early Universe, neutrinos decouple quickly from the primordial plasma and propagate without further interactions. The impact of free-streaming neutrinos is to create a tempo…

Comparing Compressed and Full-modeling Analyses with FOLPS: Implications for DESI 2024 and beyond
H. E. Noriega, A. Aviles, H. Gil-MarÃn +51
The Dark Energy Spectroscopic Instrument (DESI) will provide unprecedented information about the large-scale structure of our Universe. In this work, we study the robustness of the…
