In this presentation I will review current status of receivers at VLBI stations in Japan, including the frequency bands, bandwidths, and potential for multi-frequency receiving capability. I will focus primarily on VLBI facilities operated by the National Astronomical Observatory of Japan (NAOJ), such as the VERA network and the Nobeyama 45m radio telescope, while also briefly introducing the...

Contributed Talk

In this report, we present our recent study of the acceleration and collimation of the two-sided jets in the nearby low-luminosity AGN NGC 4261. We robustly identify a parabolic-to-conical structural transition in both the jet and counterjet, with the transition occurring on (sub)parsec scales. Based on the jet-to-counterjet brightness, we derive the jet velocity field at distances of ∼ (10^3...
