A detailed kinematic study of 3C 84 and its connection to Gamma-rays
Jeffrey A. Hodgson, Bindu Rani, Junghwan Oh +7
3C 84 (NGC 1275) is the bright radio core of the Perseus Cluster. Even in the absence of strong relativistic effects, the source has been detected at Gamma-rays up to TeV energies.…
Sirius: A Prototype Astronomical Intensity Interferometer Using Avalanche Photodiodes in Linear Mode
Junghwan Oh, Jan Wagner, Sascha Trippe +3
Optical intensity interferometry, developed in the 1950s, is a simple and inexpensive method for achieving angular resolutions on microarcsecond scales. Its low sensitivity has lim…
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…
Gamma-rays in the radio galaxy 3C 84: A complex situation
Jeffrey A. Hodgson, Bindu Rani, Junghwan Oh
3C 84 is a nearby Active Galactic Nucleus (AGN) that is unique in that is believed that we are observing near the true jet launching region - unlike blazars. The source is active i…
KVN observations suggest multiple -ray emission regions in 3C 84
Jeffrey A. Hodgson, Bindu Rani, Sang-Sung Lee +15
3C 84 (NGC 1275) is a well-studied mis-aligned Active Galactic Nucleus (AGN), which has been active in Gamma rays since at least 2008. We have monitored the source at four waveleng…
The Millimeter-Radio Emission of BL Lacertae During Two gamma-ray Outbursts
Dae-Won Kim, Sascha Trippe, Sang-Sung Lee +13
We present a study of the inexplicit connection between radio jet activity and gamma-ray emission of BL Lacertae (BL Lac; 2200+420). We analyze the long-term millimeter activity of…
