Blazar Demographics with MOJAVE and GLAST
MOJAVE is a long term VLBA program to investigate the kinematics and polarization evolution of a complete sample of 133 active galactic nuclei selected on the basis of compact, relativistically beamed jet emission at 15 GHz. By fitting to the apparent distributions of superluminal speed and jet luminosity, we can constrain the Lorentz factor distribution and intrinsic luminosity function of the...
متن کاملBlazar Demographics and Physics ASP Conference Series, Vol. ***, 200*
We discuss the preliminary results of an extensive effort to address the fundamental, and yet un-answered, question that can be trivialized as: “are there more blue or red blazars?”. This problematic is tightly connected with the much debated issue of the unified picture(s) of radio–loud AGNs, which in turn revolves around the existence, and the properties of relativistic jets. We address this ...
متن کاملTwistors and 2T-physics1
Two-Time physics applies broadly to the formulation of physics and correctly describes the physical world as we know it. Recently it was applied to a 2T reformulation of the d = 4 twistor superstring, which was suggested by Witten as an efficient approach for computations of physical processes in the maximally supersymmetric N = 4 Yang-Mills field theory in four dimensions. The 2T formalism pro...
متن کاملPossible Scales of New Physics1
The biggest question in beyond the standard model physics is what are the scales of new physics. Ideas about scales, as well as experimental evidence and constraints, are surveyed for a variety of possible forms of new physics: supersymmetry, neutrino masses, unification, and superstring theory. Plenary talk on Beyond the Standard Model Physics, DPF99 (UCLA).
متن کاملAGILE and blazar studies
During the first two years of observation, AGILE detected several blazars at high significance: 3C 279, 3C 454.3, PKS 1510–089, S5 0716+714, 3C 273, W Comae, Mrk 421 and PKS 0537–441. We obtained long-term coverage of 3C 454.3, for a total of more than three months at energies above 100 MeV. 3C 273 was the first blazar detected simultaneously by the AGILE gamma-ray detector and by its hard X-ra...
