| contents | GALACTIC DYNAMICAL STRUCTURE REVEALED BY VLBI ASTROMETRY N. Sakai Física, Astronomía y Matemáticas structure Astrometry interfometris Astrometry is the most direct and accurate method to reveal the 3D structure of the Milky Way. I review the Galactic structure based on VLBI astrometry results. First, I intro duce some basic concepts of VLBI astrometry and actual VLBI arrays. Then, I show some recent scientific results w ith VLBI astrometry, namely (i) Fundamental parameters of the Milky Way, (ii) The rotation curve of the Milky Way, and (iii) The Perseus (main) arm of the Milky Way. Finally, I briefly describe future prospects for g as and stellar astrometry in the Gaia era. 2015 artículo científico 0185-1101 https://www.redalyc.org/articulo.oa?id=57150514014 en http://www.redalyc.org/revista.oa?id=571 Revista Mexicana de Astronomía y Astrofísica application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Astronomía y Astrofísica (México) Vol.46 |
