cds-question@unistra.fractive-galactic-nucleiradio-continuum-emissionsurveysbl-lacertae-objectsquasarsradio-sourcesWe discuss acceleration measurements for a large sample of extragalactic radio jets from the Monitoring Of Jets in Active Galactic Nuclei with VLBA Experiments (MOJAVE) program, which studies the parsec-scale jet structure and kinematics of a complete, flux-density-limited sample of active galactic nuclei (AGNs). Accelerations are measured from the apparent motion of individual jet features or "components" which may represent patterns in the jet flow. We find that significant accelerations are common both parallel and perpendicular to the observed component velocities.2009ApJ...706.1253Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/706/1253CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/545/A113 : MOJAVE IX.
