When, Why, and How CMB Compression Fails
Davide Pedrotti, William Giarè, Hanyu Cheng +1
We test when compressed CMB likelihoods can be reliably used to constrain new physics beyond CDM, formulating concrete criteria for \textit{when}, \textit{why}, and \textit{how}…
Evaporating cosmologically coupled black holes
Marco Calzà, Davide Pedrotti, Massimiliano Rinaldi +1
Cosmologically coupled black holes (CCBHs), whose masses evolve in response to the cosmological expansion, have recently attracted significant theoretical and observational interes…
Hubble tension: the shape wall
Miguel A. Sabogal, Luis A. Escamilla, Davide Pedrotti +2
The standard "no-go theorem" against late-time solutions to the Hubble tension is essentially a normalization wall, since Baryon Acoustic Oscillation (BAO) measurements constrain t…
Geometric Constraints on the Pre-Recombination Expansion History from the Hubble Tension
Davide Pedrotti
I perform a model-independent reconstruction of the background pre-recombination expansion history of the Universe. I find that purely early-time resolutions to the Hubble tension,…
BAO miscalibration cannot rescue late-time solutions to the Hubble tension
Davide Pedrotti, Luis A. Escamilla, Valerio Marra +2
Baryon Acoustic Oscillation (BAO) measurements play a key role in ruling out post-recombination solutions to the Hubble tension. However, because the data compression leading to th…
Machine Learning-Based Analytical Expressions for Gray-Body Factors and Application to Primordial Black Holes
Guan-Wen Yuan, Marco Calzà, Davide Pedrotti
Symbolic Regression (SR) is a machine learning approach that explores the space of mathematical expressions to identify those that best fit a given dataset, balancing both accuracy…
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.…
Multidimensionality of the Hubble tension: the roles of and
Davide Pedrotti, Jun-Qian Jiang, Luis A. Escamilla +2
The Hubble tension is inherently multidimensional, and bears important implications for parameters beyond . We discuss the key role of the matter density parameter and t…
Nonparametric late-time expansion history reconstruction and implications for the Hubble tension in light of recent DESI and type Ia supernovae data
Jun-Qian Jiang, Davide Pedrotti, Simony Santos da Costa +1
We nonparametrically reconstruct the late-time expansion history in light of the latest Baryon Acoustic Oscillation (BAO) measurements from DESI combined with various Type Ia Super…
Neutrino cosmology after DESI: tightest mass upper limits, preference for the normal ordering, and tension with terrestrial observations
Jun-Qian Jiang, William Giarè, Stefano Gariazzo +6
The recent DESI Baryon Acoustic Oscillation measurements have led to tight upper limits on the neutrino mass sum, potentially in tension with oscillation constraints requiring $\su…
