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…
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…
Evaporating primordial black holes, the string axiverse, and hot dark radiation
Marco Calzà, John March-Russell, João G. Rosa
We show that primordial black holes (PBHs) develop non-negligible spins through Hawking emission of the large number of axion-like particles generically present in string theory co…
