H_2O maser and a plasma obscuring torus in the radio galaxy NGC 1052
S. Sawada-Satoh, S. Kameno, K. Nakamura +3
We present multi-frequency simultaneous VLBA observations at 15, 22 and 43 GHz towards the nucleus of the nearby radio galaxy NGC 1052. These three continuum images reveal a double…
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…
Distance to NGC 281 in a Galactic Fragmenting Superbubble: Parallax Measurements with VERA
Mayumi Sato, Tomoya Hirota, Mareki Honma +30
We have used the Japanese VLBI array VERA to perform high-precision astrometry of an H2O maser source in the Galactic star-forming region NGC 281 West, which has been considered to…
Positional Coincidence of H2O Maser and a Plasma Obscuring Torus in Radio Galaxy NGC 1052
Satoko Sawada-Satoh, Seiji Kameno, Kayoko Nakamura +3
We present multi-frequency simultaneous VLBA observations at 15, 22 and 43 GHz towards the nucleus of the nearby radio galaxy NGC 1052. These three continuum images reveal a double…
Distance to Orion KL Measured with VERA
Tomoya Hirota, Takeshi Bushimata, Yoon Kyung Choi +34
We present the initial results of multi-epoch VLBI observations of the 22 GHz H2O masers in the Orion KL region with VERA (VLBI Exploration of Radio Astrometry). With the VERA dual…
Absolute Proper Motions of H2O Masers Away from the Galactic Plane Measured with VERA in the "Superbubble" Region NGC 281
Mayumi Sato, Tomoya Hirota, Mareki Honma +34
We report on absolute proper-motion measurements of an H2O maser source in the NGC 281 West molecular cloud, which is located ~320 pc above the Galactic plane and is associated wit…
