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。伯德绿色银行望远镜（GBT）观测附近星系中的致密气体。 该团队为NSF的这个设施增加了一台尖端仪器Argus。 这为毫米波长的重要观测铺平了道路。 该团队将研究星系如何在其致密气体中形成恒星。 他们将把他们的观察结果与理论模型进行比较。 高级小组成员将培训从任职人数不足的群体中征聘的初级成员。 该团队将为加州的湾区科学节和西弗吉尼亚州的绿色银行游客中心提供材料。 该团队还将帮助其他人使用Argus进行自己的研究。该团队将在GBT上使用Argus以高空间分辨率绘制附近星系中的致密分子气体。 他们将联合收割机将这些新数据与其他波长的现有数据结合起来，研究（1）每单位致密气体中星星形成的数量如何取决于星系中的局部条件，以及（2）致密气体的数量如何取决于星系中的局部条件。
