This astronomy project will produce a "3-dimensional" map of the center of the Milky Way Galaxy. The team will develop a catalogue of gas and dust clouds for use by other scientists. Infrared data from the Herschel space telescope will be combined with radio observations from the APEX telescope in Chile and the MOPRA telescope in Australia. By observing radiation from warm dust and from molecules like formaldehyde, methanol, and silicon monoxide, the team will reveal the 3-D shapes, sizes, and distances of the clouds. The data will be compared to models of star formation to investigate how stars are born near the center of our Milky Way galaxy. The center of the Milky Way, known as the Central Molecular Zone (CMZ), is complicated and difficult to observe. The telescopes being used, which operate at infrared and radio wavelengths, are very well suited to this project. By comparison, optical telescopes struggle to see through the gas and dust that blocks our view of the CMZ. The CMZ includes the supermassive black hole at the heart of our galaxy, and intriguing objects like "the brick", a dense cloud that has yet to create any stars, and "the three little pigs", a row of three clumps on the verge of star birth. Understanding the CMZ is of great importance to models of the galaxy, and to theories of star birth in dense clouds.A postdoctoral researcher will be involved in this important and exciting project. The catalogue of clouds in the CMZ will be posted on an easy-to-use website. The team will also produce a custom lesson plan on the CMZ and a "WorldWide Telescope" (WWT) tour of our Galaxy's center. The lesson plan will be developed as part of the "BiteScis" program, which is led by this project's Principle Investigator (PI) and by a Boston Science Teacher. The lessons are designed to relate to curriculum standards, are tested in a local K-12 classroom, and are shared with other teachers through the BiteScis website. The WWT, a project hosted by the American Astronomical Society, will extend the reach of the CMZ survey beyond the K-12 classroom. The PI has served as an ambassador to the WWT for a number of years and is committed to including her survey data in the WWT.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.

这个天文学项目将制作银河系中心的“ 3维”地图。该团队将开发一个气体和尘埃云目录，以供其他科学家使用。 来自Herschel太空望远镜的红外数据将与智利的Apex望远镜和澳大利亚Mopra望远镜的无线电观测结合在一起。通过观察温暖的灰尘和甲醛，甲醇和一氧化硅等分子的辐射，该团队将揭示云层的3-D形状，尺寸和距离。 将数据与恒星形成模型进行比较，以研究恒星在我们银河系银河系中心附近的出生方式。银河系的中心被称为中央分子区（CMZ），很复杂且难以观察。 使用红外线和无线电波长运行的望远镜非常适合该项目。 相比之下，光学望远镜努力透过阻碍我们对CMZ的看法的气体和灰尘。 CMZ包括我们银河系中心的超大质量黑洞，以及像“砖”之类的吸引人的物体，这是一种尚未造成任何恒星的茂密云和“三只小猪”，这是星际出生的三个团块。了解CMZ对于银河系的模型以及密集的云中的恒星出生理论至关重要。 CMZ中的云目录将发布在易于使用的网站上。该团队还将制定有关CMZ的定制课程计划，并对我们的银河中心进行“全球望远镜”（WWT）巡回演出。该课程将作为“ Bitescis”计划的一部分制定，该计划由该项目的主要研究者（PI）和波士顿科学老师领导。这些课程旨在与课程标准相关联，在本地K-12教室中进行了测试，并通过Bitescis网站与其他老师共享。美国天文学会主持的一个项目将把CMZ调查的范围扩展到K-12教室。 PI多年来一直是WWT的大使，并致力于将她的调查数据包括在WWT中。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响来通过评估来支持的。
