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…
: Hawking Radiation from Regular Black Holes
Alexandre Arbey, Marco Calzà, Léa Malacher +2
We present , a major update of the public code designed to compute Hawking radiation spectra of black holes. Building upon previous versions, this release…
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…
Primordial regular black holes as all the dark matter. III. Covariant canonical quantum gravity models
Marco Calzà, Davide Pedrotti, Guan-Wen Yuan +1
In earlier companion papers, we showed that non-singular primordial black holes (PBHs) could account for all the dark matter (DM) over a significantly wider mass range compared to…
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…
Trinity of black hole correspondences: Shadows, quasinormal modes, graybody factors, and cautionary remarks
Davide Pedrotti, Marco Calzà
Correspondences between apparently distant concepts are ubiquitous in theoretical physics. In the context of black holes (BHs), quasinormal modes (QNMs) were shown to be linked to…
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.…
Primordial regular black holes as all the dark matter. II. Non-time-radial-symmetric and loop quantum gravity-inspired metrics
Marco Calzà, Davide Pedrotti, Sunny Vagnozzi
It is a common belief that a theory of quantum gravity should ultimately cure curvature singularities which are inevitable within General Relativity, and plague for instance the Sc…
Primordial regular black holes as all the dark matter. I. Time-radial-symmetric metrics
Marco Calzà, Davide Pedrotti, Sunny Vagnozzi
Primordial black holes (PBHs) are usually assumed to be described by the Schwarzschild or Kerr metrics, which however feature unwelcome singularities. We study the possibility that…
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…
Quasinormal modes-shadow correspondence for rotating regular black holes
Davide Pedrotti, Sunny Vagnozzi
Eikonal quasinormal modes (QNMs) of black holes (BHs) and parameters of null geodesics, ultimately tied to the appearance of BHs to external observers, are known to be related, and…
