Unveiling the Complex Jet Dynamics in the Blazar 2021+317 through Multiepoch Very Long Baseline Interferometry Observations
We present an investigation of the compact structure of the active galactic nucleus 2021+317 based on multiepoch very long baseline interferometry (VLBI) observations at 15, 22, and 43 GHz in the period from 2013 through 2024. The VLBI images show a core–jet structure extended to the south, with two...
