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…
