Demonstration of KVN phase referencing capability
Evangelia Tremou, Taehyun Jung, Aeree Chung +1
We present the results of Very Long Baseline Interferometry (VLBI) observations using the phase reference technique to detect weak Active Galactic Nuclei (AGN) cores in the Virgo c…
A Search for AGN Intra-day Variability with KVN
Taeseok Lee, Sascha Trippe, Junghwan Oh +3
Active galactic nuclei (AGN) are known for irregular variability on all time scales, down to intra-day variability with relative variations of a few percent within minutes to hours…
PAGaN II: The Evolution of AGN Jets on Sub-Parsec Scales
Junghwan Oh, Sascha Trippe, Sincheol Kang +7
We report first results from KVN and VERA Array (KaVA) VLBI observations obtained in the frame of our Plasma-physics of Active Galactic Nuclei (PAGaN) project. We observed eight se…
PAGaN I: Multi-Frequency Polarimetry of AGN Jets with KVN
Jae-Young Kim, Sascha Trippe, Bong Won Sohn +5
Active Galactic Nuclei (AGN) with bright radio jets offer the opportunity to study the structure of and physical conditions in relativistic outflows. For such studies, multi-freque…
Arp 65 interaction debris: massive HI displacement and star formation
Chandreyee Sengupta, Thomas. C. Scott, Sanjaya Paudel +3
Context: Pre-merger interactions between galaxies can induce significant changes in the morphologies and kinematics of the stellar and ISM components. Large amounts of gas and star…
The Power of Simultaneous Multi-Frequency Observations for mm-VLBI: Astrometry up to 130 GHz with the KVN
Maria J. Rioja, Richard Dodson, Taehyun Jung +1
Simultaneous observations at multiple frequency bands have the potential to overcome the fundamental limitation imposed by the atmospheric propagation in mm-VLBI observations. The…
