| Abstract: |
VERA (VLBI Exploration of Radio Astrometry) is a VLBI array consisting of four radio telescopes (Mizusawa, Kagoshima, Chichijima and Ishigakijima) and promoted by the National Astronomical Observatory of Japan. It aims at accurately measuring distances and proper motions of astronomical maser sources that are widely distributed over our Galaxy (the Milky Way Galaxy). The target accuracy is 10-mas level. With this high accuracy, VERA will investigate the three-dimensional structure and dynamics of our Galaxy and reveal the distribution and total amount of dark matter, which is a key to answer the fundamental question whether the universe will continue to expand indefinitely or not. Three (Mizusawa, Kagoshima and Chichijima) of the four telescopes are being constructed and will be completed in 2001. |
