This project plans to build a new calibration and highly detailed map of the present-day star formation rate in our Galaxy, the Milky Way. These maps are needed to understand how stars form in our own Galaxy and also in other unresolved, external galaxies in the universe. The PI will use the global Citizen Science network known as the Milky Way Project (MWP) to map the spatial distribution and brightness of low-density clouds of partially ionized atomic hydrogen gas in the Galaxy, known as H II regions, in order to compile the largest catalog of Galactic H II regions to date. He will also build a network of astronomy research collaboration among at Cal Poly Pomona and Cal State University campuses, and community colleges that target undergraduate students. A student-led public outreach program BUILD: Bring the Universe Into LA Districts, will educate families and friends of under-represented students about astronomy as a science and as a viable career option. This project will use the NSF-funded California-Arizona Minority Partnership for Astronomy Research and Education (CAMPARE) and California Bridge to the PhD (Cal-Bridge) programs, to strengthen STEM research at Cal Poly Pomona, which has a large Hispanic student population. The PI and his team plan to do this work using bolometric and ionizing continuum luminosities of Galactic H II regions, calibrated against star-forming rates measured from direct X-ray and infrared (IR) observations of young population of stars in massive star forming regions. They will also expand and refine the Galactic HII regions catalog using supplementary infrared and radio survey data and distance information to measure luminosities.

这个项目计划建立一个新的校准和非常详细的地图，以显示我们银河系中目前的恒星形成率。我们需要这些地图来了解恒星是如何在我们自己的星系以及宇宙中其他未解决的外部星系中形成的。PI将使用全球公民科学网络，即银河系计划（MWP）来绘制银河系中部分电离氢原子气体的低密度云的空间分布和亮度，即H II区域，以便编制迄今为止最大的银河系H II区域目录。他还将在加州波莫纳分校和加州州立大学校园以及面向本科生的社区学院之间建立一个天文学研究合作网络。一个由学生主导的公共宣传项目BUILD：将宇宙带入洛杉矶地区，将教育弱势学生的家人和朋友，让他们了解天文学是一门科学，也是一种可行的职业选择。该项目将利用美国国家科学基金会资助的加州-亚利桑那州天文学研究与教育少数族裔伙伴关系（CAMPARE）和加州桥博士（Cal-Bridge）项目，加强加州波莫纳理工学院的STEM研究，该学院拥有大量西班牙裔学生。PI和他的团队计划使用银河H区的辐射测量和电离连续光谱来完成这项工作，并根据直接x射线和红外（IR）观测大质量恒星形成区域年轻恒星群测量的恒星形成率进行校准。他们还将利用补充红外和无线电调查数据以及距离信息来测量光度，扩大和完善银河系HII区域目录。
