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)…
Trigonometric parallax and proper motion of Sagittarius A* measured by VERA using the new broad-band back-end system OCTAVE-DAS
Tomoaki Oyama, Takumi Nagayama, Aya Yamauchi +12
We successfully measured the trigonometric parallax of Sagittarius A* (Sgr A*) to be micro-arcseconds (as) using the VLBI Exploration of Radio Astrometry (VERA) with…
Astrometric VLBI observations of HO masers in an extreme OH/IR star candidate NSV17351
Akiharu Nakagawa, Atsushi Morita, Nobuyuki Sakai +14
Results of astrometric very long baseline interferometry (VLBI) observations towards an extreme OH/IR star candidate NSV17351 are presented. We used the VERA (VLBI Exploration of R…
Overview of the Observing System and Initial Scientific Accomplishments of the East Asian VLBI Network (EAVN)
Kazunori Akiyama, Juan-Carlos Algaba, Tao An +101
The East Asian VLBI Network (EAVN) is an international VLBI facility in East Asia and is operated under mutual collaboration between East Asian countries, as well as part of Southe…
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…
Annual parallax measurement of a Mira variable star BX Cam with VERA
Masako Matsuno, Akiharu Nakagawa, Atsushi Morita +8
We report results of astrometric VLBI observations toward a Mira variable star BX~Cam using the VLBI array "VERA". The observations were performed from February 2012 to November 20…
