Constraining the photon coupling of ultra-light dark-matter axion-like particles by polarization variations of parsec-scale jets in active galaxies
M. M. Ivanov, Y. Y. Kovalev, M. L. Lister +4
Ultra-light dark matter may consist of axion-like particles with masses below 10^(-19) eV. Two-photon interactions of these particles affect the polarization of radiation propagati…
MOJAVE. X. Parsec-Scale Jet Orientation Variations and Superluminal Motion in AGN
M. L. Lister, M. F. Aller, H. D. Aller +7
We describe the parsec-scale kinematics of 200 AGN jets based on 15 GHz VLBA data obtained between 1994 Aug 31 and 2011 May 1. We present new VLBA 15 GHz images of these and 59 add…
VLBA observations of a rare multiple quasar imaging event caused by refraction in the interstellar medium
A. B. Pushkarev, Y. Y. Kovalev, M. L. Lister +9
We report on the first detection of the theoretically-predicted rare phenomenon of multiple parsec-scale imaging of an active galactic nucleus induced by refractive effects due to…
Relativistic Jets in the Radio Reference Frame Image Database II: Blazar Jet Accelerations from the First 10 Years of Data (1994 - 2003)
B. G. Piner, A. B. Pushkarev, Y. Y. Kovalev +6
(Abridged) We analyze blazar jet apparent speeds and accelerations from the RDV series of astrometric and geodetic VLBI experiments. From these experiments, we have produced and an…
Single-epoch VLBI imaging study of bright active galactic nuclei at 2 and 8 GHz
A. B. Pushkarev, Y. Y. Kovalev
We investigate statistical and individual astrophysical properties of active galactic nuclei (AGNs), such as parsec-scale flux density, core dominance, angular and linear sizes, ma…
MOJAVE: Monitoring of Jets in Active Galactic Nuclei with VLBA Experiments. VIII. Faraday rotation in parsec-scale AGN jets
T. Hovatta, M. L. Lister, M. F. Aller +5
We report observations of Faraday rotation measures (RMs) for a sample of 191 extragalactic radio jets observed within the MOJAVE program. Multifrequency VLBA observations were car…
