High-Sensitivity 86GHz (3.5mm) VLBI Observations of M87: Deep Imaging of the Jet Base at a 10 Schwarzschild-Radius Resolution
Kazuhiro Hada, Motoki Kino, Akihiro Doi +9
We report on results from new high-sensitivity, high-resolution 86GHz (3.5 millimeter) observations of the jet base in the nearby radio galaxy M87, obtained by the Very Long Baseli…
Fossil shell emission in dying radio loud AGNs
M. Kino, H. Ito, N. Kawakatu +4
We investigate shell emission associated with dying radio loud AGNs. First, based on our recent work by Ito et al. (2015), we describe the dynamical and spectral evolutions of shel…
PAGaN II: The Evolution of AGN Jets on Sub-Parsec Scales
Junghwan Oh, Sascha Trippe, Sincheol Kang +7
We report first results from KVN and VERA Array (KaVA) VLBI observations obtained in the frame of our Plasma-physics of Active Galactic Nuclei (PAGaN) project. We observed eight se…
Interferometric Monitoring of Gamma-ray Bright Active Galactic Nuclei II: Frequency Phase Transfer
Juan-Carlos Algaba, Guang-Yao Zhao, Sang-Sung Lee +11
The Interferometric Monitoring of Gamma-ray Bright Active galactic nuclei (iMOGABA) program provides not only simultaneous multifrequency observations of bright gamma-ray detected…
Discovery of a wandering radio jet base after a large X-ray flare in the blazar Markarian 421
K. Niinuma, M. Kino, A. Doi +3
We investigate the location of the radio jet bases ("radio cores") of blazars in radio images, and their stationarity by means of dense very long baseline interferometry (VLBI) obs…
First Detection of 350 Micron Polarization From a Radio-loud AGN
Sang-Sung Lee, Sincheol Kang, Do-Young Byun +5
We report the first detection of linearly polarized emission at an observing wavelength of 350 m from the radio-loud Active Galactic Nucleus 3C 279. We conducted polarization ob…
