Observational signatures of an electromagnetic overcritical gravitational collapse
R. Ruffini, F. Fraschetti, L. Vitagliano +1
We present theoretical predictions for the spectral, temporal and intensity signatures of the electromagnetic radiation emitted during the process of the gravitational collapse of…
On Plasma Oscillations in Strong Electric Fields
R. Ruffini, L. Vitagliano, S. -S. Xue
We describe the creation and evolution of electron-positron pairs in a strong electric field as well as the pairs annihilation into photons. The formalism is based on generalized V…
New perspectives in physics and astrophysics from the theoretical understanding of Gamma-Ray Bursts
R. Ruffini, C. L. Bianco, P. Chardonnet +3
If due attention is given in formulating the basic equations for the Gamma-Ray Burst (GRB) phenomenon and in performing the corresponding quantitative analysis, GRBs open a main av…
Energy Extraction From Gravitational Collapse to Static Black Holes
Remo Ruffini, Luca Vitagliano
The mass--energy formula of black holes implies that up to 50% of the energy can be extracted from a static black hole. Such a result is reexamined using the recently established a…
