The First Very Long Baseline Interferometry Image of 44 GHz Methanol Maser with the KVN and VERA Array (KaVA)
Naoko Matsumoto, Tomoya Hirota, Koichiro Sugiyama +58
We have carried out the first very long baseline interferometry (VLBI) imaging of 44 GHz class I methanol maser (7_{0}-6_{1}A^{+}) associated with a millimeter core MM2 in a massiv…
Multi-epoch VERA Observations of H2O masers in OH 43.8-0.1
M. Honma, T. Bushimata, Y. K. Choi +33
We report on the multi-epoch observations of H2O maser emission in star forming region OH 43.8-0.1 carried out with VLBI Exploration of Radio Astrometry (VERA). The large-scale mas…
First Fringe Detection with VERA's Dual-Beam System and its Phase Referencing Capability
M. Honma, T. Fujii, T. Hirota +25
We present the results of first dual-beam observations with VERA (VLBI Exploration of Radio Astrometry). The first dual-beam observations of a pair of H2O maser sources W49N and OH…
Microlensing optical depth towards the Galactic bulge from MOA observations during 2000 with Difference Image Analysis
T. Sumi, F. Abe, I. A. Bond +27
We analyze the data of the gravitational microlensing survey carried out by by the MOA group during 2000 towards the Galactic Bulge (GB). Our observations are designed to detect ef…
The Minimum Total Mass of MACHOs and Halo Models of the Galaxy
T. Nakamura, Y. Kan-ya, R. Nishi
If the density distribution ρ(r) of MACHOs is spherically symmetric with respect to the Galactic center, it is shown that the minimal total mass M_{min}^{ MACHO} of the MACHOs is 1…
