FLASHING: New high-velocity HO masers in IRAS 182860959
Hiroshi Imai, Yuri Uno, Daichi Maeyama +8
We discovered new high-velocity components of HO maser emission in one of the "water fountain" sources, IRAS~182860959, which has been monitored using the Nobeyama 45 m tele…
Disk-Driven Rotating Bipolar Outflow in Orion Source I
Tomoya Hirota, Masahiro N. Machida, Yuko Matsushita +5
One of the outstanding problems in star-formation theory concerns the transfer of angular momentum such that mass can accrete onto a newly born young stellar object (YSO). From a t…
Bowshocks in a newly discovered maser source in IRAS 20231+3440
Chikaedu Ogbodo, Ross Burns, Toshihiro Handa +7
From measuring the annual parallax of water masers over one and a half years with VERA, we present the trigonometric parallax and corresponding distance of another newly identified…
H2O masers in a jet-driven bowshock: Episodic ejection from a massive young stellar object
R. A. Burns, T. Handa, T. Nagayama +2
We report the results of VERA multi-epoch VLBI 22 GHz water maser observations of S255IR-SMA1, a massive young stellar object located in the S255 star forming region. By annual par…
Radio Astrometry towards the Nearby Universe with the SKA
Hiroshi Imai, Ross A. Burns, Yoshiyuki Yamada +5
This chapter summarizes radio astrometry in relation to current very long baseline interferometry (VLBI) projects and describes its perspectives with the SKA. The scientific goals…
Outer Rotation Curve of the Galaxy with VERA II: Annual Parallax and Proper Motion of the Star-Forming Region IRAS21379+5106
Hiroyuki Nakanishi, Nobuyuki Sakai, Tomoharu Kurayama +7
We conducted astrometric VLBI observations of water-vapor maser emission in the massive star forming region IRAS 21379+5106 to measure the annual parallax and proper motion, using…
