RadioAstron space-VLBI imaging of the jet in M87: II. The parsec-scale structure at 4.8 GHz
Evgeniya V. Kravchenko, Tuomas Savolainen, Alexey S. Nikonov +9
We present RadioAstron observations of the M87 jet obtained on 2014 February 4-5 at 4.8 GHz ( cm). The correlated signals between the 10-m space antenna and ground-based rad…
Search for refractive substructure in active galactic nuclei using ground-based VLBI observations
Tatiana A. Koryukova, Alexander V. Plavin, Alexander B. Pushkarev +1
We present the results of the first systematic search for refractive scattering substructure in active galactic nuclei (AGN) using ground-based very long baseline interferometry (V…
Detection of Compton scattering in the jet of 3C 84
Ioannis Liodakis, Sudip Chakraborty, Frédéric Marin +77
3C 84 is the brightest cluster galaxy in the Perseus Cluster. It is among the closest radio-loud active galaxies and among the very few that can be detected from low frequency radi…
How Spatially Resolved Polarimetry Informs Black Hole Accretion Flow Models
Angelo Ricarte, Michael D. Johnson, Yuri Y. Kovalev +2
The Event Horizon Telescope (EHT) Collaboration has successfully produced images of two supermassive black holes, enabling novel tests of black holes and their accretion flows on h…
Probing the innermost regions of AGN jets and their magnetic fields with RadioAstron. V. Space and ground millimeter-VLBI imaging of OJ 287
Jose L. Gómez, Efthalia Traianou, Thomas P. Krichbaum +27
We present the first polarimetric space VLBI observations of OJ 287, observed with RadioAstron at 22 GHz during a perigee session on 2014 April 4 and five near-in-time snapshots, t…
