The East-Asian VLBI Network
Kiyoaki Wajima, Yoshiaki Hagiwara, Tao An +14
The East-Asian VLBI Network (EAVN) is the international VLBI facility in East Asia and is conducted in collaboration with China, Japan, and Korea. The EAVN consists of VLBI arrays…
High-resolution CO observation of the carbon star CIT 6 revealing the spiral structure and a nascent bipolar outflow
Hyosun Kim, Sheng-Yuan Liu, Naomi Hirano +8
CIT 6 is a carbon star in the transitional phase from the asymptotic giant branch (AGB) to the protoplanetary nebulae (pPN). Observational evidences of two point sources in the opt…
Amplitude Correction Factors of KVN Observations
Sang-Sung Lee, Do-Young Byun, Chung Sik Oh +7
We report results of investigation of amplitude calibration for very long baseline interferometry (VLBI) observations with Korean VLBI Network (KVN). Amplitude correction factors a…
Dynamical evolution of supernova remnants breaking through molecular clouds
Wankee Cho, Jongsoo Kim, Bon-Chul Koo
We carry out three-dimensional hydrodynamic simulations of the supernova remnants (SNRs) produced inside molecular clouds (MCs) near their surface using the HLL code (Harten et al.…
A New Hardware Correlator in Korea: Performance Evaluation using KVN observations
Sang-Sung Lee, Chung Sik Oh, Duk-Gyoo Roh +10
We report results of the performance evaluation of a new hardware correlator in Korea, the Daejeon correlator, developed by the Korea Astronomy and Space Science Institute (KASI) a…
Power spectra of outflow-driven turbulence
Anthony Moraghan, Jongsoo Kim, Suk-Jin Yoon
We investigate the power spectra of outflow-driven turbulence through high-resolution three-dimensional isothermal numerical simulations where the turbulence is driven locally in r…
