Radio and -ray activity in the jet of the blazar S5 0716714
Dae-Won Kim, Evgeniya V. Kravchenko, Alexander M. Kutkin +11
We explore the connection between the -ray and radio emission in the jet of the blazar 0716714 by using 15, 37, and 230 GHz radio and 0.1200 GeV -ray light curves spann…
Deep Transfer Learning for Classification of Variable Sources
Dae-Won Kim, Doyeob Yeo, Coryn A. L. Bailer-Jones +1
Ongoing or upcoming surveys such as Gaia, ZTF, or LSST will observe light-curves of billons or more astronomical sources. This presents new challenges for identifying interesting a…
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…
Investigating the connection between gamma-ray activity and relativistic jet in 3C273 during 2015-2019
Dae-Won Kim, Sascha Trippe, Evgeniya V. Kravchenko
Due to its powerful radiation over the entire electromagnetic spectrum and its radio jet activity, the blazar 3C273 offers the opportunity to study the physics of -ray emission…
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…
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…
