Registering Gaia positions on VLBI images: constraining opacity-driven core shift in B 1038+528 / B 1038+529
M. H. Xu, Y. Y. Kovalev
Because of the complex and time-variable radio structure of active galactic nuclei (AGNs), absolute astrometric positions cannot generally be registered unambiguously with specific…
SKA-VLBI Probes of High-energy Emission Processes in Relativistic Jets
M. Kadler, E. K. Bempong-Manful, P. G. Edwards +10
Relativistic jets in the nuclei of active galaxies are ubiquitous sources of high-energy emission. In particular, blazars represent the most luminous persistent X-ray and gamma-ray…
A hidden ultra-relativistic spine in the jet of a neutrino-associated blazar
Y. Y. Kovalev, F. Eppel, D. C. Homan +16
Supermassive black holes launch powerful jets of plasma that can accelerate particles to extreme energies, but the physical conditions required to produce high-energy neutrinos rem…
The Emerging Population of High-energy Emitting Radio Galaxies
G. Bruni, V. S. Paliya, D. J. Saikia +22
High-energy emission from radio galaxies provides a unique laboratory to study the connection between accretion, jet formation, and particle acceleration in active galactic nuclei…
SKA VLBI survey of the Southern sky for astrometry, geodesy, and astrophysics
M. H. Xu, L. Y. Petrov, Y. Y. Kovalev
The development of SKA will open the opportunity to run dedicated VLBI surveys of the Southern sky and observe sources not visible at radio telescopes located in the Northern hemis…
Broadband multiwavelength properties of the archetypal blazar 3C 279 during the 2017 Event Horizon Telescope campaign
G. Principe, J. C. Algaba, E. Aviano +529
The archetypal blazar 3C 279 hosts a prominent relativistic jet and exhibits strong broadband variability across the electromagnetic spectrum. In April 2017, the Event Horizon Tele…
