VLBI observations of bright AGN jets with KVN and VERA Array (KaVA): Evaluation of Imaging Capability
Kotaro Niinuma, Sang-Sung Lee, Motoki Kino +69
The Korean very-long-baseline interferometry (VLBI) network (KVN) and VLBI Exploration of Radio Astrometry (VERA) Array (KaVA) is the first international VLBI array dedicated to hi…
Astrometry of Star Forming Region IRAS 05137+3919 in the far outer Galaxy
Mareki Honma, Tomoya Hirota, Yukitoshi Kan-ya +4
We present the results of astrometric observations with VERA toward the H2O maser sources in IRAS 05137+3919, which is thought to be located in the far outer Galaxy. We have derive…
Astrometry of HO masers in the massive star--forming region IRAS 06061+2151 with VERA
Kotaro Niinuma, Takumi Nagayama, Tomoya Hirota +8
We measured the trigonometric annual parallax of HO maser source associated with the massive star-forming regions IRAS 06061+2151 with VERA. The annual parallax of $0.496\pm0.0…
VLBI Astrometry of AGB Variables with VERA -- A Semiregular Variable S Crateris --
Akiharu Nakagawa, Miyuki Tsushima, Kazuma Ando +40
We present a distance measurement for the semiregular variable S Crateris (S Crt) based on its annual parallax. With the unique dual beam system of the VLBI Exploration for Radio A…
Distance to VY Canis Majoris with VERA
Yoon Kyung Choi, Tomoya Hirota, Mareki Honma +33
We report astrometric observations of H2O masers around the red supergiant VY Canis Majoris (VY CMa) carried out with VLBI Exploration of Radio Astrometry (VERA). Based on astromet…
Astrometry of HO Masers in Nearby Star-Forming Regions with VERA. III. IRAS 22198+6336 in L1204G
Tomoya Hirota, Kazuma Ando, Takeshi Bushimata +35
We present results of multi-epoch VLBI observations with VERA (VLBI Exploration of Radio Astrometry) of the 22 GHz HO masers associated with a young stellar object (YSO) IRAS…
