Maria Wimberly is awarded a Mathematical and Physical Sciences Ascending Postdoctoral Research Fellowship (MPS-Ascend) to conduct a program of research and education at the University of California, Riverside. She plans a study of near–field cosmology and numerical modeling of galactic star formation. She has extensive experience with hydrodynamic simulations that include star formation models. These models yield different predictions of heavy element production in ultra–faint dwarf galaxies, which depend on the environment where the stars formed. She will improve the Cal–Bridge Scholarship’s peer mentorship program, to broaden the participation of underrepresented minorities in Physics & Astronomy by strengthening genuine camaraderie. The program includes specific personalized professional development planning for these young, diverse scientists. Wimberley will compare models of predicted element abundances to observations of galaxies in different environments, to determine which physical processes are most important in these environments. A key question she seeks to answer is what fraction of the Milky Way’s ultra–faint dwarf galaxies were never satellites of other smaller galaxy systems, prior to entering the Milky Way’s system. She seeks to learn what fraction of the Milky Way’s satellite galaxies are true, pristine relics of the first galaxies ever formed. These galaxies are optimal sites to search for signatures of the first stars ever formed. Within the expanded Cal-Bridge program, she plans a vertical mentoring structure. These peer mentorship activities provide space for students to create a community around equity through normalizing common struggles, individual holistic success, and determining how to improve their academic experience. This type of group work/mentoring organically creates leadership opportunities and a thriving community.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.

玛丽亚·温伯利（Maria Wimberly）被授予数学和物理科学上升博士后研究奖学金（MPS-Ascend），在加州大学滨江分校开展研究和教育项目。她计划研究近场宇宙学和银河系星星形成的数值模拟。 她在包括星星形成模型在内的流体动力学模拟方面拥有丰富的经验。这些模型对超暗矮星系中重元素的产生了不同的预测，这取决于恒星形成的环境。她将改善Cal-Bridge奖学金的同行指导计划，通过加强真正的同志情谊来扩大物理天文学中代表性不足的少数民族的参与。 该计划包括为这些年轻，多样化的科学家制定具体的个性化专业发展规划。Wimberley将比较预测元素丰度的模型与不同环境中星系的观测结果，以确定哪些物理过程在这些环境中最重要。她试图回答的一个关键问题是，在进入银河系之前，银河系中有多少超微弱的矮星系从未是其他较小星系系统的卫星。她试图了解银河系的卫星星系中有哪一部分是真正的，是有史以来形成的第一个星系的原始遗迹。 这些星系是寻找有史以来第一批恒星的最佳地点。 在扩大的卡尔桥计划，她计划一个垂直的指导结构。 这些同伴指导活动为学生提供了空间，通过正常化共同斗争，个人整体成功，并确定如何改善他们的学术经验，围绕公平创建一个社区。这种类型的小组工作/指导有机地创造了领导机会和繁荣的社区。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。
