项目摘要
This program will develop a better understanding of the way in which fuel for star formation settles into the galactic disk of the Milky Way from the intergalactic medium. This goal will be accomplished through the use of survey data from the Arecibo Observatory that helps trace the location of gas in and near our Milky Way galaxy. Broader impacts of the work include training of undergraduate and graduate students. The project will have a direct impact on society through a program that brings astronomers into diverse middle schools throughout New York City. The goal is to inspire students at a juncture where they often choose to turn towards or away from science.Dr. Putman and her students will construct a multiphase map of the interface between the disk and halo of the Milky Way through the combination of a catalog of clouds from the GALFA-HI Survey, examination of their dust content, and comparisons to models and multi-wavelength observational data. The process of cooling at the disk-halo interface will be explored, as well as the interplay between accretion and feedback in controlling the star formation rate.
该计划将更好地了解形成星星的燃料从星系际介质进入银河系银盘的方式。这一目标将通过使用阿雷西博天文台的调查数据来实现,该数据有助于追踪我们银河系及其附近的气体位置。这项工作的更广泛影响包括培训本科生和研究生。 该项目将通过一个将天文学家带入整个纽约市不同中学的计划对社会产生直接影响。Putman博士和她的学生将通过GALFA-HI调查的云目录,检查其尘埃含量,并与模型和多波长观测数据进行比较,构建银河系盘和晕之间界面的多相地图。将探索盘-晕界面的冷却过程,以及吸积和反馈在控制星星形成速率方面的相互作用。
