Monitoring of GAmma-ray Bright AGN : The Multi-frequency Polarization of the Flaring Blazar 3C 279
Sincheol Kang, Sang-Sung Lee, Do-Young Byun
We present results of long-term multi-wavelength polarization observations of the powerful blazar 3C~279 after its -ray flare on 2013~December 20. We followed up this flare with…
A Search for AGN Intra-day Variability with KVN
Taeseok Lee, Sascha Trippe, Junghwan Oh +3
Active galactic nuclei (AGN) are known for irregular variability on all time scales, down to intra-day variability with relative variations of a few percent within minutes to hours…
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…
PAGaN I: Multi-Frequency Polarimetry of AGN Jets with KVN
Jae-Young Kim, Sascha Trippe, Bong Won Sohn +5
Active Galactic Nuclei (AGN) with bright radio jets offer the opportunity to study the structure of and physical conditions in relativistic outflows. For such studies, multi-freque…
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…
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…
