Claire Murray is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to conduct a program of research and education at Johns Hopkins University. Murray will observe dusty gas in the Milky Way to accurately account for the obscuration or "reddening" of starlight by the intervening matter. This would allow astronomers to understand the complex structure of the Milky Way and its evolution, as well as to accurately interpret observations of extragalactic light which passes through the matter in the Milky Way. Alongside this research, Murray will develop an outreach program to promote stargazing in urban settings.Murray will study dusty gas using high-resolution large-scale observations of atomic hydrogen available from the Galactic Arecibo L-band Feed Array-HI survey. She will also use reddening estimates from Gaia Data Release 2 to calibrate the relationship between gas and dust properties. This will allow her to produce a map of interstellar reddening at the highest resolution and fidelity possible to date. In addition, Murray will characterize the neutral envelopes of star-forming regions and the effect of the Galactic environment on the transition from atomic to molecular gas. For the educational component of her work, Murray will develop a program for public engagement with astronomy in urban areas, and she will deploy this program through a series of educational presentations in local state parks.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

克莱尔·默里（Claire Murray）被授予NSF天文学和天体物理学博士后奖学金，以在约翰·霍普金斯大学（Johns Hopkins University）进行研究和教育计划。 默里（Murray）将以银河系的方式观察到尘土飞扬的气体，以准确说明介入物质对星光的晦涩或“变红”。 这将使天文学家能够理解银河系的复杂结构及其进化，并准确地解释了以银河系的经历的观察结果。 除了这项研究外，默里还将制定一项外展计划，以促进城市环境中的星焦。 她还将使用Gaia Data Release 2中的红色估计值来校准气体和灰尘特性之间的关系。 这将使她能够以最高的分辨率和迄今为止可能的忠诚度生产一张星际地图。 此外，穆雷将表征恒星形成区域的中性信封以及银河环境对从原子气体到分子气体的过渡的影响。 对于她作品的教育部分，默里将制定一项计划，以公开与城市地区的天文学参与，她将通过在当地州立公园的一系列教育演讲来部署该计划。这项奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子和更广泛影响的评估来通过评估来支持的，这是值得的。
