Importance of being nonminimally coupled: Scalar Hawking radiation from regular black holes
Marco Calzà, Massimiliano Rinaldi, Sunny Vagnozzi
In curved space-time, a scalar field is generically expected to couple to curvature, via a coupling of the form . Yet in the study of Hawking emission from regular black…
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…
