Verification of the Polarimetric Capability of the East Asia VLBI Network
Yunjeong Lee, Jongho Park, Do-Young Byun +10
The East Asia VLBI Network (EAVN) has recently enabled dual-polarization observations at and . We present the first systematic verification of its polarimetr…
A High-frequency Geodetic VLBI Experiment for Optical Clock Comparison
Monia Negusini, Myoung-Sun Heo, Cecilia Clivati +40
An intercontinental metrological clock comparison between Italy and the Republic of Korea was performed by means of geodetic K-band VLBI observations. The comparison involved the h…
Enhanced imaging of M87*: Simulations with the EHT and extended-KVN
Ilje Cho, Jongho Park, Do-Young Byun +16
The Event Horizon Telescope (EHT) has successfully revealed the shadow of the supermassive black hole, M87*, with an unprecedented angular resolution of approximately 20 uas at 230…
A Geodetic and Astrometric VLBI Experiment at 22/43/88/132 GHz
Shuangjing Xu, Taehyun Jung, Bo Zhang +14
Extending geodetic and astrometric Very Long Baseline Interferometry (VLBI) observations from traditional centimeter wavebands to millimeter wavebands offers numerous scientific po…
GPCAL: a generalized calibration pipeline for instrumental polarization in VLBI data
Jongho Park, Do-Young Byun, Keiichi Asada +1
We present the Generalized Polarization CALibration pipeline (GPCAL), an automated pipeline for instrumental polarization calibration of very long baseline interferometry (VLBI) da…
SYMBA: An end-to-end VLBI synthetic data generation pipeline
F. Roelofs, M. Janssen, I. Natarajan +203
Realistic synthetic observations of theoretical source models are essential for our understanding of real observational data. In using synthetic data, one can verify the extent to…
