Is cosmic birefringence due to dark energy or dark matter? Simulation-based inference
Florie Carralot, Patricia Diego-Palazuelos, Adriaan J. Duivenvoorden +3
Simulation-based inference (SBI) is a powerful inference technique for cases where the exact functional form of the likelihood is not known. A prime example is the likelihood of cr…

CDM and early dark energy in latent space: a data-driven parametrization of the CMB temperature power spectrum
Davide Piras, Laura Herold, Luisa Lucie-Smith +1
Finding the best parametrization for cosmological models in the absence of first-principle theories is an open question. We propose a data-driven parametrization of cosmological mo…
