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…
MOJAVE XIX: Brightness Temperatures and Intrinsic Properties of Blazar Jets
D. C. Homan, M. H. Cohen, T. Hovatta +7
We present multi-epoch, parsec-scale core brightness temperature observations of 447 AGN jets from the MOJAVE and 2cm Survey programs at 15 GHz from 1994 to 2019. The brightness te…
MOJAVE: XVIII. Kinematics and Inner Jet Evolution of Bright Radio-Loud Active Galaxies
M. L. Lister, D. C. Homan, K. I. Kellermann +4
We have analyzed the parsec-scale jet kinematics of 447 bright radio-loud AGN, based on 15 GHz VLBA data obtained between 1994 August 31 and 2019 August 4. We present new total int…
The Highly Self-Absorbed Blazar, PKS\,1351018
Brian Punsly, Sandor Frey, Cormac Reynolds +5
PKS\,1351018 at a redshift of is one of the most luminous, steady synchrotron sources with a luminosity \,erg~s. The synchrotron luminosity does not s…
A decade of joint MOJAVE-Fermi AGN monitoring: localisation of the gamma-ray emission region
I. G. Kramarenko, A. B. Pushkarev, Y. Y. Kovalev +3
Within the MOJAVE VLBA program (Monitoring of Jets in AGN with VLBA Experiments), we have accumulated observational data at 15 GHz for hundreds of jets in -ray bright active gal…
Is OJ 287 a Single Supermassive Black Hole?
M. S. Butuzova, A. B. Pushkarev
Light curves for more than century optical photometric observations of the blazar OJ 287 reveals strong flares with a quasi-period of about 12 years. For a long time, this period h…
