Statistical Nuances in BAO Analysis: Likelihood Formulations and Non-Gaussianities
Denitsa Staicova
We present a systematic comparison of statistical approaches to Baryon Acoustic Oscillation (BAO) analysis using DESI DR2 data. We evaluate four methods for handling the nuisance p…
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.…
Electromagnetic Waves in Cosmological Space-Time II. Luminosity Distance
Denitsa Staicova, Michail Stoilov
In this article, we continue our investigation on how the electromagnetic waves propagate in the Friedman-Lemaitre-Robertson-Walker spacetime. Unlike the standard approach, which r…
Modern Bayesian Sampling Methods for Cosmological Inference: A Comparative Study
Denitsa Staicova
We present a comprehensive comparison of different Markov Chain Monte Carlo (MCMC) sampling methods, evaluating their performance on both standard test problems and cosmological pa…
