Fast radio bursts (FRBs) are transient pulses of radio emission lasting only milliseconds. They are known to be coming from galaxies outside our own and are now a highly intense area of astrophysical pursuit, with over a thousand FRBs detected to date. A research team between the University of California Santa Cruz, Northwestern University and the Maria Mitchell Observatory (MMO) forms the core of the Fast and Fortunate for FRB Follow-up (F4) team, which has been funded by the NSF since 2019 to observe FRBs and associate them with their host galaxies. This has enabled the team to start to use FRB signals to probe the universe and to make a new census of the baryons (subatomic particles, mostly protons and neutrons) in a highly diffuse state outside of galaxies throughout the universe. This current NSF award extends this work to allow F4 to increase its observational impact by an order of magnitude through follow-up observations of two new surveys of precisely localized FRBs, allowing them to study cosmology, baryon distribution and identify FRB progenitors. This award will also support students in a postbaccalaureate 'Bridge' program hosted at the MMO for attracting and retaining talented and traditionally underrepresented students, with a long-term goal of increasing their participation and leadership in STEM fields. All of the investigators will engage in the many outreach activities of the MMO.During the period of this grant, the F4 team will acquire, analyze, and disseminate deep, multi-band imaging and spectroscopy on the host galaxies of hundreds of FRBs across the sky. For many tens of FRB fields, they will obtain imaging and multi-object spectroscopy to identify intervening galactic halos and map the foreground large-scale structure. These data and derived quantities (e.g. redshifts (z) and stellar masses), together with measurements of the FRBs (e.g. dispersion measure (DM) and rotation measure (RM)) will enable three major scientific thrusts: (1) cosmology: the first statistically robust determination of the Macquart relation (DM vs. z), leading to a new and complementary estimate of the Hubble parameter; (2) galaxy formation: inferring the radial distribution of baryons in galactic halos and constraining the magnetic fields and gas density of the circumgalactic medium; and (3) FRB progenitors: testing the many models invoked to produce FRBs and using rapid follow-up imaging at radio, optical and X-ray wavelengths to resolve FRB emission mechanisms.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.

快速无线电脉冲串 (FRB) 是仅持续几毫秒的瞬态无线电发射脉冲。 众所周知，它们来自我们星系之外的星系，现在是天体物理学研究的高度集中的领域，迄今为止已检测到超过一千个快速射电暴。 加州大学圣克鲁斯分校、西北大学和玛丽亚·米切尔天文台 (MMO) 组成的研究小组构成了快速射电暴后续行动 (F4) 团队的核心，该团队自 2019 年以来一直得到美国国家科学基金会的资助，以观测快速射电暴并将其与其宿主星系联系起来。这使得该团队能够开始使用 FRB 信号来探测宇宙，并对整个宇宙中星系外高度扩散状态的重子（亚原子粒子，主要是质子和中子）进行新的普查。 目前的 NSF 奖项扩展了这项工作，使 F4 通过对精确定位的 FRB 的两次新调查进行后续观测，将其观测影响提高一个数量级，使他们能够研究宇宙学、重子分布并识别 FRB 祖细胞。 该奖项还将支持 MMO 主办的学士后“桥梁”计划的学生，以吸引和留住有才华且传统上代表性不足的学生，长期目标是提高他们在 STEM 领域的参与度和领导力。 所有研究人员都将参与 MMO 的许多外展活动。在这笔资助期间，F4 团队将获取、分析和传播天空中数百个 FRB 的宿主星系的深层多波段成像和光谱。对于数十个快速射电暴场，他们将获得成像和多目标光谱来识别介入的星系晕并绘制前景大尺度结构。这些数据和导出的量（例如红移（z）和恒星质量），加上快速射电暴的测量（例如色散测量（DM）和旋转测量（RM））将实现三个主要的科学推动力：（1）宇宙学：首次在统计上稳健地确定麦夸特关系（DM与z），从而对哈勃参数进行新的补充估计； （2）星系形成：推断星系晕中重子的径向分布，约束环星系介质的磁场和气体密度； (3) FRB 前身：测试用于产生 FRB 的许多模型，并使用无线电、光学和 X 射线波长的快速后续成像来解决 FRB 发射机制。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
