Multi-wavelength differential astrometry of the S5 polar cap sample
J. C. Guirado, J. M. Marcaide, E. Ros +2
We report on the status of our S5 polar cap astrometry program. Since 1997 we have observed all the 13 radio sources of the complete S5 polar cap sample at the wavelengths of 3.6 c…
Simulations of the relativistic parsec-scale jet in 3C273
M. Perucho, A. P. Lobanov, J. M. Marti
We present a hydrodynamical 3D simulation of the relativistic jet in 3C273, in comparison to previous linear perturbation analysis of Kelvin-Helmholtz instability developing in the…
The massive analytic invariant charge in QCD
A. V. Nesterenko, J. Papavassiliou
The low energy behavior of a recently proposed model for the massive analytic running coupling of QCD is studied. This running coupling has no unphysical singularities, and in the…
The QCD analytic running coupling and chiral symmetry breaking
A. V. Nesterenko, J. Papavassiliou
We study the dependence on the pion mass of the QCD effective charge by employing the dispersion relations for the Adler D function. This new massive analytic running coupling is c…
The QCD analytic effective charge and its dependence on the pion mass
A. V. Nesterenko, J. Papavassiliou
A new model for the QCD analytic running coupling, which incorporates the effects due to the meson mass, is proposed. The properties of this invariant charge in spacelike and t…
Absolute kinematics of radio source components in the complete S5 polar cap sample
M. A. Perez-Torres, J. M. Marcaide, J. C. Guirado +1
We observed the thirteen extragalactic radio sources of the complete S5 polar cap sample at 15.4 GHz with the Very Long Baseline Array, on 27 July 1999 (1999.57) and 15 June 2000 (…
