The Dark-side of the Milky Way

点击翻译按钮获取中文摘要

Astronomers have long sought to determine the 3-dimensional structure of our Galaxy, the Milky Way, with limited success owing to its immense size and obscuration by dust at optical wavelengths. We know more about structure of tens of thousands of other galaxies than we do about the structure of the Milky Way on the far-side of the Galactic Centre. This program will use Australian infrastructure to make the most accurate distance measurements to date of the far-side of the Milky Way visible from the Southern hemisphere, completing the 3-dimensional picture of our Galaxy. These results will be leveraged to yield accurate distances, providing fundamental information on the stellar masses, luminosities, and ages.
