Observations of H2O maser sources in Orion-Monoceros Molecular Clouds with VERA
T. Hirota, VERA project team
We present results of phase-referencing VLBI observations of water maser sources in Orion-Monoceros Molecular Clouds with VERA (VLBI Exploration of Radio Astrometry), which is newl…
Distance of W3(OH) by VLBI annual parallax measurement
K. Hachisuka, A. Brunthaler, Y. Hagiwara +4
The most powerful tool for measuring distances within our Galaxy is the annual parallax. We carried out phase-referencing VLBI observations of HO masers in the star forming r…
Studies of resonance conditions on neutrino oscillations in matter
Y. Kamo, S. Yajima, Y. Higasida +2
We analytically discuss the resonance conditions among several neutrinos in matter. The discriminant for the characteristic equation of the Hamiltonian is expressed by the coeffici…
VERA Observation of the W49N H2O Maser Outburst in 2003 October
M. Honma, Y. K. Choi, T. Bushimata +33
We report on a strong outburst of the W49N H2O maser observed with VERA. Single-dish monitoring with VERA 20 m telescopes detected a strong outburst of the maser feature at V_LSR =…
SiO Maser Survey of the Large-Amplitude Variables in the Galactic Center
S. Deguchi, H. Imai, T. Fujii +7
We have surveyed ~400 known large-amplitude variables within 15' of the galactic center in the SiO J=1--0 v=1 and 2 maser lines at 43 GHz, resulting in 179 detections. SiO lines we…
Chemical composition of UV-bright star ZNG 4 in the globular cluster M13
S. Ambika, M. Parthasarathy, W. Aoki +4
We present a detailed model-atmosphere analysis of ZNG 4, a UV-bright star in the globular cluster M13. From the analysis of a high resolution () spectrum of th…
