报告题目:Maser astrometry with BeSSeL, status and progress
报 告 人:吴元伟(紫金山天文台)
报告摘要:Bright and compect maser emissions from high mass star forming regions are good target for VLBI astrometry. BeSSeL is such a project by investigating Structure and dynamics of the Milky Way by maser astrometry. Recently, we have got more than one hundred of maser parallaxes. Based on these measurements, we studied geometry, 3D motions of the spiral arms. I will report status and progress we got recently.
