Partial Alignment of Astrometric Position Excursions of International Celestial Reference Frame Quasars with Radio Jet Structures

open access: yesThe Astrophysical Journal Letters
Published analyses of very long baseline interferometry data for the sources included in the third International Celestial Reference Frame catalog have revealed object-specific, excess astrometric variability and quasi-coherent trajectories as functions ...

Minor-merger-induced Star Formation Rejuvenation in an Elliptical Radio-loud Quasar Host, 3C 59

open access: yesThe Astrophysical Journal
We report a rare case where an elliptical radio-loud quasar host, 3C 59, rejuvenates star formation activity through minor mergers with its nearby satellite galaxies.
