用于光谱分析的自动化流水线

Automated Pipelines for Spectroscopic Analysis

Carlos Allende Prieto

摘要:

盖亚任务将对我们理解银河系的结构和动力学产生深远的影响。盖亚提供了一个详尽的恒星松弛,自行,位置,颜色和径向速度的普查,但也留下了一些在其他完整的数据集耀斑漏洞。星载高分辨率摄谱仪测量的径向速度将仅达到任务中天体测量和光度测量全部恒星样本的10%左右,而详细的化学信息将不到1%。世界各地的团队正在组织大型项目,以提供互补的径向速度和化学,因为现在可以非常有效地从地面完成,这要归功于具有宽视场和多目标光谱仪的大型和中型望远镜。因此,自动化数据处理的相关性越来越大,这一概念正应用于从目标定位到分析的更多领域。在本文中,我提供了最近,正在进行和即将进行的光谱调查的快速概述,以及在其自动分析管道中采用的策略。

英文摘要:

The Gaia mission will have a profound impact on our understanding of the structure and dynamics of the Milky Way. Gaia is providing an exhaustive census of stellar parallaxes, proper motions, positions, colors and radial velocities, but also leaves some flaring holes in an otherwise complete data set. The radial velocities measured with the on-board high-resolution spectrograph will only reach some 10% of the full sample of stars with astrometry and photometry from the mission, and detailed chemical information will be obtained for less than 1%. Teams all over the world are organizing large-scale projects to provide complementary radial velocities and chemistry, since this can now be done very efficiently from the ground thanks to large and mid-size telescopes with a wide field-of-view and multi-object spectrographs. As a result, automated data processing is taking an ever increasing relevance, and the concept is applying to many more areas, from targeting to analysis. In this paper, I provide a quick overview of recent, ongoing, and upcoming spectroscopic surveys, and the strategies adopted in their automated analysis pipelines.
