The role of the screen factor in GRBs
Giuliano Preparata Remo Ruffini, She-Sheng Xue
We derive the screen factor for the radiation flux from an optically thick plasma of electron-positron pairs and photons, created by vacuum polarization process around a black hole…

On the physical processes which lie at the bases of time variability of GRBs
R. Ruffini, C. L. Bianco, P. Chardonnet +2
The relative-space-time-transformation (RSTT) paradigm and the interpretation of the burst-structure (IBS) paradigm are applied to probe the origin of the time variability of GRBs.…

On the pair-electromagnetic pulse from an electromagnetic Black Hole surrounded by a Baryonic Remnant
Remo Ruffini, Jay D. Salmonson, James R. Wilson +1
The interaction of an expanding Pair-Electromagnetic pulse (PEM pulse) with a shell of baryonic matter surrounding a Black Hole with electromagnetic structure (EMBH) is analyzed fo…
