How is the blazar GeV emission really produced?
Markos Georganopoulos, Eric Perlman, Demosthenes Kazanas +1
We show that the external Compton (EC) model for the production of the GeV emission in blazars makes specific predictions for the spectrum and variability of those blazars characte…

Modeling the Hard X-Ray Lag and Energy Spectrum of Cyg X-1
Xin-Min Hua, Demosthenes Kazanas, Wei Cui
In an effort to model the observed energy spectrum of Cygnus X-1 as well as its hard X-ray lag by Comptonization in inhomogeneous clouds of hot electrons with spherical geometry an…

Higgs Mechanism and the Structure of the Energy-Momentum Tensor in Einstein Gravity and Conformal Gravity
Philip D. Mannheim, Demosthenes Kazanas
In the standard treatment of the Einstein gravitational theory the energy-momentum tensor has always been taken to be composed of perfect fluid aggregates of kinematic Newtonian po…
