Cosmic absorption of ultra high energy particles
This paper summarizes the limits on propagation of ultra high energy particles in the Universe, set up by their interactions with cosmic background of photons and neutrinos. By taking into accountExpand

Observational signatures of an electromagnetic overcritical gravitational collapse
We present theoretical predictions for the spectral, temporal and intensity signatures of the electromagnetic radiation emitted during the process of the gravitational collapse of a stellar core to aExpand

Relativistic Feynman-Metropolis-Teller theory for white dwarfs in general relativity
The recent formulation of the relativistic Thomas-Fermi model within the Feynman-Metropolis-Teller theory for compressed atoms is applied to the study of general relativistic white dwarf equilibriumExpand

On a Possible Gamma-Ray Burst-Supernova Time Sequence
The data from the Chandra satellite on the iron emission lines in the afterglow of GRB 991216 are used to give further support to the theory that links the origin of the energy of gamma-ray burstsExpand

The Klein first integrals in an equilibrium system with electromagnetic, weak, strong and gravitational interactions
Abstract The isothermal Tolman condition and the constancy of the Klein potentials originally expressed for the sole gravitational interaction in a single fluid are here generalized to the case of aExpand

On the Structure of the Burst and Afterglow of Gamma-Ray Bursts I
We have recently proposed three paradigms for the theoretical interpretation of gamma-ray bursts (GRBs). (1) The relative space–time transformation (RSTT) paradigm emphasizes how the knowledge of theExpand

Early X-ray Flares in GRBs
We analyze the early X-ray flares in the GRB "flare-plateau-afterglow" (FPA) phase observed by Swift-XRT. The FPA occurs only in one of the seven GRB subclasses: the binary-driven hypernovae (BdHNe).Expand

On the Instantaneous Spectrum of Gamma-Ray Bursts
A theoretical attempt to identify the physical process responsible for the afterglow emission of Gamma-Ray Bursts (GRBs) is presented, leading to the occurrence of thermal emission in the comovingExpand

New perspectives in physics and astrophysics from the theoretical understanding of Gamma‐Ray Bursts
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 avenue of inquiringExpand
