The intrinsic structure of Sagittarius A* at 1.3 cm and 7 mm
Ilje Cho, Guang-Yao Zhao, Tomohisa Kawashima +63
Sagittarius A* (Sgr A*), the Galactic Center supermassive black hole (SMBH), is one of the best targets to resolve the innermost region of SMBH with very long baseline interferomet…
East Asian VLBI Network Observations of Active Galactic Nuclei Jets: Imaging with KaVA+Tianma+Nanshan
Yuzhu Cui, Kazuhiro Hada, Motoki Kino +74
The East Asian very-long-baseline interferometry (VLBI) Network (EAVN) is a rapidly evolving international VLBI array that is currently promoted under joint efforts among China, Ja…
Kinematics of the M87 jet in the collimation zone: gradual acceleration and velocity stratification
Jongho Park, Kazuhiro Hada, Motoki Kino +36
We study the kinematics of the M87 jet using the first year data of the KVN and VERA Array (KaVA) large program, which has densely monitored the jet at 22 and 43 GHz since 2016. We…
Jet Kinematics of the Quasar 4C +21.35 from Observations with the KaVA Very Long Baseline Interferometry Array
Taeseok Lee, Sascha Trippe, Motoki Kino +39
We present the jet kinematics of the flat spectrum radio quasar (FSRQ) 4C +21.35 using time-resolved KaVA very long baseline interferometry array radio maps obtained from September…
A broad HCO+ absorption line associated with the circumnuclear torus of NGC 1052
Satoko Sawada-Satoh, Do-Young Byun, Sang-Sung Lee +8
In the circumnuclear region of the nearby radio galaxy NGC~1052. Our 3mm VLBI observations with the Korean VLBI Network have spatially resolved the broad HCO absorption at…
Spatially Resolved HCN Absorption Features in the Circumnuclear Region of NGC 1052
Satoko Sawada-Satoh, Duk-Gyoo Roh, Se-Jin Oh +7
We present the first VLBI detection of HCN molecular absorption in the nearby active galactic nucleus NGC 1052. Utilizing the 1 milliarcsecond resolution achieved by the Korean VLB…
Astrometrically Registered Simultaneous Observations of the 22 GHz HO and the 43GHz SiO masers towards R Leonis Minoris using KVN and Source/Frequency Phase Referencing
Richard Dodson, María J. Rioja, Tae-Hyun Jung +22
Oxygen-rich Asymptotic Giant Branch (AGB) stars can be intense emitters of SiO (=1 and 2, J=10) and HO maser lines at 43 and 22 GHz, respectively. VLBI observat…
