| ABSTRACT : | |
| Within the general gauge principle (GGP) (G.T-Gh., 1997, Nuovo Cimento,
Sec.B, v.112, No6, 825-838; gr-qc/9710058) we explore a considerable change
of properties of space-time continuum in the central parts of AGNs in
density range above the nucleus. Employing the physics of superdense
protomatter (PSPM) we present detailed theoretical and numerical analysis
of models of equilibrium configurations of degenerate fermion gas with
many phase stratified layers. A major difference from standard black hole
models is as follows
- The superdense cores of protomatter with thermodynamical properties
strongly differed from the one of ordinary matter are formed, where the
energy density and internal pressure have sharply arose proportional to
gravitational forces in about 18-20 order of magnitude with respect to
corresponding central values of neutron star. This counteracts the
collapse and equilibrium holds even for the masses $M\simeq 3.48\times
10^{8}M_{\odot}$.
- Such cores are found inside the even horizon sphere and could be
observed only in presence of accreting matter in their close vicinities.
Versus the central values of the parameters of these cores surrounded by
the accretion disks these configurations are considered as the models of
AGNs.
- A singularity of metric no longer holds because of the action
of the metric singularity cutoff (MSC) effect. It is important for the
AGNs to which the accreting matter has steadily filled the inside of even
horizon sphere and in due course has formed a shell of superdense
protomatter near the horizon. Due to action of MSC effect above an energy
density threshold value the even horizon will be vanished and the
particles and light can escape to the outside world.
- The PSPM and MSC are of importance for a study of neutrino cooling of
the superdense protomatter core of AGN (origin of the 'primary' EHE
neutrinos), as well of the origin of the cosmological backround neutrinos
(CBN) with masses (0.1-10) eV in hot dark matter (HDM), which are the
crucial elements required for the air showers above GZK cutoff.
