Alleviating prior dependencies for DESI DR1 clustering fits through reparameterization
Marco Bonici, Simone Paradiso, Glenn McGee +48
Bayesian analyses of the full-shape clustering of Dark Energy Spectroscopic Instrument (DESI) Data Release 1 (DR1) exhibit prior-volume projection effects, whereby weakly constrain…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Planck constraints on the scale dependence of isotropic cosmic birefringence
M. Ballardini, A. Gruppuso, S. Paradiso +2
The rotation of the linear polarisation plane of photons during propagation, also known as cosmic birefringence, is a powerful probe of parity-violating extensions of standard elec…
Reducing nuisance prior sensitivity via non-linear reparameterization, with application to EFT analyses of large-scale structure
S. Paradiso, M. Bonici, M. Chen +4
Many physical models contain nuisance parameters that quantify unknown properties of an experiment that are not of primary relevance. Typically, these cannot be measured except by…
HOD-informed prior for EFT-based full-shape analyses of LSS
Hanyu Zhang, Marco Bonici, Guido D'Amico +2
To improve the performance of full-shape analyses of large-scale structure, we consider using a halo occupation distribution (HOD)-informed prior for the effective field theory (EF…
