Analytically discussed is the dynamical properties of spiraling elliptic beams in nonlocal nonlinear media. This class carry orbital angular momentum (OAM), and can rotate on cross section perpendicular to propagation direction during propagations. The optical intensity, beam width, specially velocity are both analytically numerically details. We shown that deviations from critical power OAM make breathe. decrease (increase) or increase (decrease) breathers contract (diffract), however,...
Abstract High-redshift radio sources provide plentiful opportunities for studying the formation and evolution of early galaxies supermassive black holes. However, number known radio-loud active galactic nuclei (AGN) above redshift 4 is rather limited. At high redshifts, it appears that blazars, with relativistically beamed jets pointing toward observer, are in majority compared to misaligned respect line sight. To find more these AGN, milliarcsecond-scale imaging studies carried out very...

Volonteri et al. (2011) found that the number of radio-loud quasars above redshift 4 calculated from luminosity function (based upon Swift/BAT observations) is much smaller than estimated known high-redshift beamed sources, blazars, assuming for every source with a Lorentz factor $\Gamma$, statistically $2 \Gamma^2$ non-beamed sources should exist. To explain missing misaligned (non-beamed) population they proposed various explanations, involving heavy optical obscuration and significantly...
