Faraday rotation in the jet of M87 inside the Bondi radius: indication of winds from hot accretion flows confining the relativistic jet
Jongho Park, Kazuhiro Hada, Motoki Kino +3
We study Faraday rotation in the jet of M87 inside the Bondi radius using eight Very Long Baseline Array data sets, one at 8 GHz, four at 5 GHz, and three at 2 GHz. We obtain Farad…
Parabolic Jets from the Spinning Black Hole in M87
Masanori Nakamura, Keiichi Asada, Kazuhiro Hada +18
The M87 jet is extensively examined by utilizing general relativistic magnetohydrodynamic (GRMHD) simulations as well as the steady axisymmetric force-free electrodynamic (FFE) sol…
Evidence of jet-clump interaction: a flip of the radio jet head of 3C~84
M. Kino, K. Wajima, N. Kawakatu +6
Radio jets in active galaxies have been expected to interact with circumnuclear environments in their early phase evolutions. By performing the multi-epoch monitoring observation w…
VERA monitoring of the radio jet 3C 84 during 2007--2013: detection of non-linear motion
Koichiro Hiura, Hiroshi Nagai, Motoki Kino +13
We present a kinematic study of the subparsec-scale radio jet of the radio galaxy 3C 84/NGC 1275 with the VLBI Exploration of Radio Astrometry (VERA) array at 22 GHz for 80 epochs…
Collimation, Acceleration and Recollimation Shock in the Jet of Gamma-Ray-emitting Radio-Loud Narrow-Line Seyfert 1 Galaxy 1H 0323+342
Kazuhiro Hada, Akihiro Doi, Kiyoaki Wajima +6
We investigated the detailed radio structure of the jet of 1H 0323+342 using high-resolution multi-frequency Very Long Baseline Array observations. This source is known as the near…
Revealing the Nature of Blazar Radio Cores through Multi-Frequency Polarization Observations with the Korean VLBI Network
Jongho Park, Minchul Kam, Sascha Trippe +13
We study the linear polarization of the radio cores of eight blazars simultaneously at 22, 43, and 86 GHz with observations obtained by the Korean VLBI Network (KVN) in three epoch…
