The high brightness temperature of B0529+483 revealed by RadioAstron and implications for interstellar scattering
S. V. Pilipenko, Y. Y. Kovalev, A. S. Andrianov +22
The high brightness temperatures, K, detected in several active galactic nuclei by RadioAstron space VLBI observations challenge theoretical limits. R…
Probing the innermost regions of AGN jets and their magnetic fields with RadioAstron II. Observations of 3C 273 at minimum activity
G. Bruni, J. L. Gómez, C. Casadio +18
RadioAstron is a 10 m orbiting radio telescope mounted on the Spektr-R satellite, launched in 2011, performing Space Very Long Baseline Interferometry (SVLBI) observations supporte…
PKS 1954-388: RadioAstron Detection on 80,000 km Baselines and Multiwavelength Observations
P. G. Edwards, Y. Y. Kovalev, R. Ojha +24
We present results from a multiwavelength study of the blazar PKS 1954-388 at radio, UV, X-ray, and gamma-ray energies. A RadioAstron observation at 1.66 GHz in June 2012 resulted…
A connection between -ray and parsec-scale radio flares in the blazar 3C 273
Mikhail Lisakov, Yuri Y. Kovalev, Tuomas Savolainen +2
We present a comprehensive 5-43 GHz VLBA study of the blazar 3C 273 initiated after an onset of a strong -ray flare in this source. We have analyzed the kinematics of new-born c…
