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…
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…
Probing the gamma-ray variability in 3C279 using broadband observations
B. Rani, T. P. Krichbaum, S. -S. Lee +5
We present the results of a broadband radio-to-GeV observing campaign organized to get a better understanding of the radiation processes responsible for the -ray flares observed…
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…
Exploring the nature of broadband variability in the FSRQ 3C 273
C. Chidiac, B. Rani, T. P. Krichbaum +12
Detailed investigation of broadband flux variability in the blazar 3C 273 allows us to probe the location and size of emission regions and their physical conditions. We report the…
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…
