The team will use the Robert C. Byrd Green Bank Telescope (GBT) to observe the dense gas in nearby galaxies. The team has added a cutting-edge instrument, Argus, to this NSF facility. This has paved the way for these important observations at millimeter wavelengths. The team will study how galaxies form stars in their dense gas. They will compare their observations to theoretical models. Senior team members will train junior members recruited from underrepresented groups. The team will feature the research in materials for the Bay Area Science Festival in California and the Green Bank Visitors Center in West Virginia. The team will also help others use Argus for their own research.The team will use Argus on the GBT to map the dense molecular gas in nearby galaxies at high spatial resolution. They will combine these new data with existing data at other wavelengths to study (1) how the amount of star formation per unit of dense gas depends on the local conditions in the galaxies, and (2) how the amount of dense gas depends on the local conditions in the galaxies.

该团队将使用罗伯特·c·伯德绿岸望远镜（GBT）来观测附近星系中的致密气体。研究小组在国家科学基金会的设施里增加了一种尖端仪器，阿古斯。这为这些重要的毫米波观测铺平了道路。该团队将研究星系如何在稠密的气体中形成恒星。他们将把观测结果与理论模型进行比较。高级团队成员将培训从代表性不足的群体中招募的初级成员。该团队将在加利福尼亚海湾地区科学节和西弗吉尼亚州绿色银行游客中心的材料中展示研究成果。该团队还将帮助其他人使用Argus进行自己的研究。该团队将利用GBT上的Argus以高空间分辨率绘制附近星系中密集分子气体的地图。他们将把这些新数据与其他波长的现有数据结合起来，研究(1)每单位致密气体的恒星形成数量如何取决于星系的局部条件；(2)致密气体的数量如何取决于星系的局部条件。
