Kinematics of the M87 jet in the collimation zone: gradual acceleration and velocity stratification
Jongho Park, Kazuhiro Hada, Motoki Kino +36
We study the kinematics of the M87 jet using the first year data of the KVN and VERA Array (KaVA) large program, which has densely monitored the jet at 22 and 43 GHz since 2016. We…
Ejection of Double knots from the radio core of PKS 1510--089 during the strong gamma-ray flares in 2015
Jongho Park, Sang-Sung Lee, Jae-Young Kim +8
PKS 1510--089 is a bright and active -ray source that showed strong and complex -ray flares in mid-2015 during which the Major Atmospheric Gamma Imaging Cherenkov telescopes…
Jet Kinematics of the Quasar 4C +21.35 from Observations with the KaVA Very Long Baseline Interferometry Array
Taeseok Lee, Sascha Trippe, Motoki Kino +39
We present the jet kinematics of the flat spectrum radio quasar (FSRQ) 4C +21.35 using time-resolved KaVA very long baseline interferometry array radio maps obtained from September…
Source-Frequency Phase-Referencing Observation of AGNs with KaVA Using Simultaneous Dual-Frequency Receiving
Guang-Yao Zhao, Taehyun Jung, Bong Won Sohn +27
The KVN(Korean VLBI Network)-style simultaneous multi-frequency receiving mode is demonstrated to be promising for mm-VLBI observations. Recently, other Very long baseline interfer…
Core-Jet Blending Effects in Active Galactic Nuclei under the Korean VLBI Network View at 43 GHz
Juan-Carlos Algaba, Jeffrey Hodgson, Sin-Cheol Kang +5
A long standing problem in the study of Active Galactic Nuclei (AGNs) is that the observed VLBI core is in fact a blending of the actual AGN core (classically defined by the …
