Astrometry of Water Maser Sources in Nearby Molecular Clouds with VERA - II. SVS 13 in NGC 1333
Tomoya Hirota, Takeshi Bushimata, Yoon Kyung Choi +25
We report on the results of multi-epoch VLBI observations with VERA (VLBI Exploration of Radio Astrometry) of the 22 GHz H2O masers associated with the young stellar object SVS 13…
Astrometry of Galactic Star Forming Region Sharpless 269 with VERA : Parallax Measurements and Constraint on Outer Rotation Curve
Mareki Honma, Takeshi Bushimata, Yoon Kyung Choi +28
We have performed high-precision astrometry of H2O maser sources in Galactic star forming region Sharpless 269 (S269) with VERA. We have successfully detected a trigonometric paral…
Radiation Testing of Consumer High-Speed LSI Chips for the Next Space VLBI Mission, VSOP-2
Kiyoaki Wajima, Noriyuki Kawaguchi, Yasuhiro Murata +1
We performed two types of radiation testing on high-speed LSI chips to test their suitability for use in wideband observations by the Japanese next space VLBI mission, VSOP-2. In t…
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…
Japanese VLBI Network observations of radio-loud narrow-line Seyfert 1 galaxies
Akihiro Doi, Kenta Fujisawa, Makoto Inoue +20
We performed phase-reference very long baseline interferometry (VLBI) observations on five radio-loud narrow-line Seyfert 1 galaxies (NLS1s) at 8.4 GHz with the Japanese VLBI Netwo…
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…
