Verification of the Polarimetric Capability of the East Asia VLBI Network

Yunjeong Lee, Jongho Park, Do-Young Byun +10

The East Asia VLBI Network (EAVN) has recently enabled dual-polarization observations at and . We present the first systematic verification of its polarimetr…

Where within the 3C 84 jet are -rays produced?

Georgios F. Paraschos, Ioannis Liodakis, Svetlana Jorstad +49

The location of -ray creation and emission within extra-galactic jets is a matter of active debate. One particularly well-suited source to pinpoint the location is the nearby, b…

Magnetic field strength constraints on -ray flaring regions in the flat spectrum radio quasar PKS 1222+216

Yeji Jo, Sang-Sung Lee

We present a multi-wavelength study of the Flat Spectrum Radio Quasar PKS 1222+216, analyzing its long-term variability of radio data obtained in 2013-2020 from the iMOGABA, MOJAVE…

A distance measurement for blazar TXS 0506+056 using its radio variability and very long baseline images

Chanwoo Song, Sang-Sung Lee, Sincheol Kang +1

We present the results of constraining the angular diameter distance to blazar TXS 0506+056. We used data obtained with the 15 GHz VLBA in MJD 54838-60262 and data from the 15 GHz…

Detection of Compton scattering in the jet of 3C 84

Ioannis Liodakis, Sudip Chakraborty, Frédéric Marin +77

3C 84 is the brightest cluster galaxy in the Perseus Cluster. It is among the closest radio-loud active galaxies and among the very few that can be detected from low frequency radi…

The variability angular diameter distance and the intrinsic brightness temperature of active galactic nuclei

Whee Yeon Cheong, Sang-Sung Lee, Chanwoo Song +5

Context. It has recently been suggested that angular diameter distances derived from comparing the variability timescales of blazars to angular size measurements with very long bas…
