  • The mass formula of Black Holes and its application for Gamma Ray Bursts

Remo Ruffini (Nice) and Donato Bini (Rome)

The rotational and electromagnetic energy of Black Holes are linked to energy source of Gamma Ray Bursts via study of exact analytic and numerical solution of collapsing shell in General Relativity. The definition of the Blackholic energy is analyzed also in connection to the electrodynamic properties of the Fermi solution in Special Relativity. Recent work by R. Jantzen is generalized.

  • Improved relativistic moment of inertia of rotating Neutron Stars

Remo Ruffini (Rome) ad Jorge Rueda (Rome)

A self consistent model of rotating Neutron Stars fulfilling General Relativistic treatment as well as electromagnetic, weak and strong interactions is explored, as well as its consequences for observations.

  • URCA process in a collapsing core endowed with electromagnetic structure

Remo Ruffini and She-Sheng Xue

The case of collapsing core fulfilling general relativistic, electromagnetic, weak and strong interactions is being studied with special attention to the URCA process. The number fluxes and energy spectra of neutrino and anti-neutrino emission are studied.

  • The study of transparency of electron-positron-baryon plasma

Alexey Aksenov, Remo Ruffini and Gregory Vereshchagin

The sources of Gamma Ray Bursts are optically thick and contain electron-positron plasma which plays important dynamical role providing self accelerated expansion of plasma. As result of expansion eventually it becomes transparent to photons, trapped during optically thick phase. Such photons are emitted as a strong flash of radiation identified as P-GRB within the fireshell model of GRBs. The thesis is expected to focus on the study of transparency of electron-positron plasma with baryonic loading by combining relativistic hydrodynamic and kinetic treatments

  • The role of 17 keV neutrinos in cosmological structure formation

Remo Ruffini and Gregory Vereshchagin

A unified approach to halos in globular clusters, dwarf galaxies and galaxies as well as nuclear condensations in galactic cores are analyzed within General Relativity and quantum statistics.
