First Trigonometric Parallax Measurements with the KVN and VERA Array (KaVA)
Nobuyuki Sakai, Daisuke Sakai, Noriyuki Kawaguchi +26
To demonstrate the astrometric capability of the combined Korean VLBI (Very Long Baseline Interferometry) Network (KVN) and VLBI Exploration of Radio Astrometry (VERA) Array (KaVA)…
EAVN Astrometry toward the Extreme Outer Galaxy: Kinematic distance with the proper motion of G034.84-00.95
Nobuyuki Sakai, Bo Zhang, Shuangjing Xu +22
We aim to reveal the structure and kinematics of the Outer-Scutum-Centaurus (OSC) arm located on the far side of the Milky Way through very long baseline interferometry (VLBI) astr…
VERA astrometry toward the Perseus arm gap
Nobuyuki Sakai, Hiroyuki Nakanishi, Kohei Kurahara +4
The Perseus arm has a gap in Galactic longitudes (l) between 50 and 80 deg (hereafter the Perseus arm gap) where the arm has little star formation activity. To better understand th…
The First VERA Astrometry Catalog
VERA collaboration, Tomoya Hirota, Takumi Nagayama +59
We present the first astrometry catalog from the Japanese VLBI (very long baseline interferometer) project VERA (VLBI Exploration of Radio Astrometry). We have compiled all the ast…
Searches for HO Masers toward Narrow-Line Seyfert 1 galaxies
Yoshiaki Hagiwara, Akihiro Doi, Kazuya Hachisuka +1
We present searches for 22 GHz HO masers toward 36 narrow-line Seyfert 1 galaxies (NLS1s), selected from known NLS1s with 41000 km/s. Out of the 36 NLS1s i…
A Face-on Accretion System in High-Mass Star-Formation: Possible Dusty Infall Streams within 100 AU
Kazuhito Motogi, Tomoya Hirota, Kazuo Sorai +7
We report on interferometric observations of a face-on accretion system around the High-Mass young stellar object, G353.273+0.641. The innermost accretion system of 100 au radius w…
