星系凸起的内在形状

The intrinsic shape of galaxy bulges

J. Mendez-Abreu

摘要:

星系组成部分的内在三维(3D)结构的知识提供了关于驱动其形成和演化的物理过程的关键信息。在本文中,我将讨论在寻求更好地了解星系凸起的3D形状的主要发展和结果。我从建立问题的基本几何描述开始。我们的理解的内在形状的椭圆星系和星系盘,然后在历史背景下,以放置的作用,3D结构的凸起发挥更广泛的图片星系演化。我们目前对银河系隆起的三维形状和未来的前景在该领域的看法也被描绘。

英文摘要:

The knowledge of the intrinsic three-dimensional (3D) structure of galaxy components provides crucial information about the physical processes driving their formation and evolution. In this paper I discuss the main developments and results in the quest to better understand the 3D shape of galaxy bulges. I start by establishing the basic geometrical description of the problem. Our understanding of the intrinsic shape of elliptical galaxies and galaxy discs is then presented in a historical context, in order to place the role that the 3D structure of bulges play in the broader picture of galaxy evolution. Our current view on the 3D shape of the Milky Way bulge and future prospects in the field are also depicted.
