A Unified Origin of Faraday Rotation toward 3C 84: The Circumnuclear Ambient Medium within the Parsec-scale Bondi Radius of the Host Galaxy NGC 1275

The Astrophysical Journal
We present multifrequency polarimetric observations of 3C 84 obtained with the Korean VLBI Network at 43–141 GHz, the Very Long Baseline Array at 43 GHz, and the High Sensitivity Array at 8 GHz from 2015 to 2024. We find that the Faraday rotation measure
