Topological regular black holes without Cauchy horizon
Marco Calzá, Massimiliano Rinaldi, Sergio Zerbini
Regular and spherically symmetric black holes that solve the singularity problems of the Schwarzschild solution are phenomenologically viable at large distance but usually suffer f…

Gray-body factors: Method matters
Alexandre Arbey, Marco Calzà, Yuber F. Perez-Gonzalez
The calculation of gray-body factors is essential for understanding Hawking radiation and black hole thermodynamics. While the formalism developed by Chandrasekhar is effective for…

: A public code for calculating the Gray Body Factors of massless fields around spherically symmetric Black Holes
Marco Calzá
We introduce and describe , a publicly available Mathematica-based tool designed for the efficient computation of gray-body factors for spherically symmetric and asym…
