: 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…
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…
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…
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…
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…
