Multi-Messenger Emission Characteristics of Blazars

Multi-Messenger observations and theory of astrophysical objects is fast becoming a critical research area in the astrophysics scientific community. In particular, point-like objects like that of BL Lac, flat spectrum radio quasars (FSRQ), and blazar candidates of uncertain type (BCU) are of distinct interest among those who look at the synchrotron, Compton, neutrino, and cosmic ray emissions sourced from compact objects. Notably, there is also much interest in the correlation between multi-frequency observations of blazars and neutrino surveys on source demographics. In this review we look at such multi-frequency and multi-physics correlations of the radio, X-ray, and $\gamma$-ray fluxes of different classes of blazars from a collection of survey catalogues. This multi-physics survey of blazars shows that there are characteristic cross-correlations in the spectra of blazars when considering their multi-frequency and multi-messenger emission. Accompanying this will be a review of cosmic ray and neutrino emissions from blazars and their characteristics.

Viscoelastic Theory Representation Of Gravitational Strain Fields In The ${}^+Λ$-CDM Vacuum

In recent years, investigations of gravitational interactions has led us to discover new facets of the fundamental force. With these discoveries the general theory of relativity is under greater scrutiny now than it was 100 years ago. Development of a more advanced theory is needed for experimental tests and extensive predictions of gravitational interactions in local and cosmological settings. In this work, we present axioms of a novel theory that describes spacetime as a relativistic viscoelastic continuum; retaining the properties of the natural ${}^{+}Λ$-CDM vacuum. With these axioms, we provide a foundation for a tensor field theory of Gravitational Strain; introduced as an advanced formulation of an elastic interpretation of gravitational interactions. This viscoelastic definition of gravity is a natural advancement of general relativity to an observable measure of a proper relativistic gravitational field.

Characterization of Electron Pair Velocity in YBa$_{2}$Cu$_{3}$O$_{7-\textit{$δ$}}$ Thin Films

The superconducting phase transition in YBa$_{2}$Cu$_{3}$O$_{7-\textit{$δ$}}$(YBCO) thin film samples doped with non-superconducting nanodot impurities of CeO$_{2}$ are the focus of recent high-temperature superconductor studies. Non-superconducting holes of the superconducting lattice induce a bound-state of circulating paired electrons. This creates a magnetic flux vortex state. Examining the flow of free-electrons shows that these quantized magnetic flux vortices arrange themselves in a self-assembled lattice. The nanodots serve to present structural properties to constrict the "creep" of these flux vorticies under a field response in the form of a pinning-force enhancing the critical current density after phase transition. In this work, a model for characterizing the superconducting phase by the work done on electron pairs and chemical potential, following the well-known theories of Superconductivity (Bardeen-Cooper-Scheifer \& Ginzburg-Landau), is formulated and tested.A solution to the expression for the magnetic flux, zero net force and pair velocity will generate a setting for the optimal deposition parameters of number density, growth geometry and mass density of these nanodot structures.
