Multiple simultaneous Gamma-ray emission sites in 3C 84
Jeffrey A. Hodgson, S. S. Lee, B. Rani +1
The mis-aligned active galactic nuclei (AGN), 3C\,84, has been observed approximately monthly at four frequencies simultaneously (22\,GHz -- 129\,GHz) on the Korean VLBI Network (K…
Interferometric Monitoring of Gamma-ray Bright AGNs I: Results of Single-epoch Multifrequency Observations
Sang-Sung Lee, Kyoaki Wajima, Juan-Carlos Algaba +12
We present results of single-epoch very long baseline interferometry (VLBI) observations of gamma-ray bright active galactic nuclei (AGNs) using the Korean VLBI Network (KVN) at 22…
From galaxy-scale fueling to nuclear-scale feedback: the merger-state of radio galaxies 3C293, 3C305 & 4C12.50
Bjorn Emonts, Raffaella Morganti, Montserrat Villar-Martin +5
Powerful radio galaxies are often associated with gas-rich galaxy mergers. These mergers may provide the fuel to trigger starburst and active galactic nuclear (AGN) activity. In th…
Exploring the magnetic field configuration in BL Lac using GMVA
B. Rani, T. P. Krichbaum, J. Hodgson +5
The high radio frequency polarization imaging of non-thermal emission from active galactic nuclei (AGN) is a direct way to probe the magnetic field strength and structure in the im…
The automatic calibration of Korean VLBI Network data
Jeffrey A. Hodgson, Sang-Sung Lee, Guang-Yao Zhao +4
The calibration of Very Long Baseline Interferometry (VLBI) data has long been a time consuming process. The Korean VLBI Network (KVN) is a simple array consisting of three identic…
Location of Gamma-ray emission and magnetic field strengths in OJ 287
J. A. Hodgson, T. P. Krichbaum, A. P. Marscher +19
The Gamma-ray BL Lac object OJ 287 is known to exhibit inner-parsec "jet-wobbling", high degrees of variability at all wavelengths and quasi-stationary features including an appare…
Location and origin of gamma-rays in blazars
B. Rani, T. P. Krichbaum, J. A. Hodgson +1
One of the most intriguing and challenging quests of current astrophysics is to understand the physical conditions and processes responsible for production of high-energy particles…
