Interferometric Monitoring of Gamma-ray Bright AGNs: OJ 287
Jee Won Lee, Sang-Sung Lee, Juan-Carlos Algaba +9
We present the results of simultaneous multi-frequency imaging observations at 22, 43, 86, and 129\,GHz of OJ\,287. We used the Korean VLBI Network as part of the Interferometric M…
Origin and Evolution of the Multi-band Variability in the Flat Spectrum Radio Source 4C 38.41
Juan Carlos Algaba, Sang Sung Lee, Bindu Rani +13
The flat spectrum radio quasar 4C 38.41 showed a significant increase of its radio flux density during the period 2012 March - 2015 August which correlates with gamma-ray flaring a…
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 …
Exploring the Nature of the 2016 γ-ray Emission in the Blazar 1749+096
Dae-Won Kim, Sascha Trippe, Sang-Sung Lee +9
Recent Fermi-Large Area Telescope (LAT) light curves indicate an active -ray state spanning about five months from 2016 June to 2016 October in the BL Lac object 1749+096 (OT 08…
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…
Exploring the Variability of the Flat Spectrum Radio Source 1633+382. II: Physical Properties
Juan-Carlos Algaba, Sang-Sung Lee, Bindu Rani +13
The flat spectrum radio quasar 1633+382 (4C~38.41) showed a significant increase of its radio flux density during the period 2012 March - 2015 August which correlates with gamma-ra…
