Observations of SiO Maser Sources within a Few Parsec from the Galactic Center
Abstract Mapping and monitoring observations of SiO maser sources near the Galactic center were made with the Nobeyama 45-m telescope at 43 GHz. Rectangular mapping an area of approximately $200^{\prime\prime} \times 100^{\prime\prime}$ in a ${30{}^{\mathrm {\prime \prime }}}$ grid, and triangular mapping in a ${20{}^{\mathrm {\prime \prime }}}$ grid toward …
