Amy Sardone is awarded an NSF Astronomy and Astrophysics Postdoctoral Fellowship to conduct a program of research and education at the Ohio State University. Sardone will study how large-scale atomic hydrogen gas around galaxies is converted into molecular hydrogen and fuels star formation in small-scale molecular gas clouds within galaxies. Alongside this research, Sardone will implement a science research mentoring program for high school students from groups that are traditionally underrepresented in science, technology, engineering, and mathematics (STEM). Sardone will measure the inflow of atomic hydrogen, identify star-forming regions, and study the relationship between the atomic hydrogen gas and molecular hydrogen gas in a large sample of nearby galaxies. This will allow astronomers to understand the transition between the atomic and molecular gas, and its role in controlling star formation in galaxies. For the educational component of her work, Sardone will conduct a research mentoring program aimed at improving the recruitment, retention, and success of low-income and underrepresented minority students in STEM fields.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.

艾米·萨多内被授予NSF天文学和天体物理学博士后奖学金，在俄亥俄州州立大学进行研究和教育计划。 Sardone将研究星系周围的大规模原子氢气如何转化为分子氢，并在星系内的小规模分子气体云中为星星的形成提供燃料。 除了这项研究，Sardone还将为传统上在科学，技术，工程和数学（STEM）方面代表性不足的高中生实施科学研究指导计划。Sardone将测量氢原子的流入，识别恒星形成区域，并研究附近星系大样本中氢原子气体和氢分子气体之间的关系。 这将使天文学家了解原子和分子气体之间的过渡，以及它在控制星系中星星形成中的作用。 对于她工作的教育部分，Sardone将开展一项研究指导计划，旨在改善低收入和代表性不足的少数民族学生在STEM领域的招聘，保留和成功。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
