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.

快速无线电爆发（FRB）是无线电发射的瞬态脉冲，仅持续毫秒。 众所周知，它们来自我们自己之外的星系，现在是天体物理追求的高度强度，迄今为止发现了一千多个FRB。 加利福尼亚大学圣克鲁斯大学，西北大学和玛丽亚·米切尔天文台（MMO）的研究团队构成了FRB随访（F4）的快速而幸运的核心，该团队自2019年以来一直由NSF资助，以观察FRB，并将其与他们的宿主星系相关联。这使团队能够开始使用FRB信号来探测宇宙，并在整个宇宙的星系以外的高度分散状态下对重子（亚原子颗粒，主要是质子和中子）进行新的普查。 当前的NSF奖项扩展了这项工作，以使F4通过对两项精确局部FRB的两项新调查进行随访，从而通过数量级来增加其观察力的影响，从而使他们能够研究宇宙学，Baryon分布并识别FRB祖细胞。 该奖项还将在MMO举办的Bacccalaureate的“桥梁”计划中为学生提供支持，该计划是吸引并保留了有才华和传统的人数不足的学生，其长期目标是增加他们在STEM领域的参与和领导力。 所有调查人员都将从事MMO的许多外展活动。在这笔赠款的期间，F4团队将在数百个FRB的宿主星系上获取，分析和传播深层，多频段的成像和光谱。对于许多数十万个FRB字段，它们将获得成像和多对象光谱，以识别中间的银河卤素并绘制前景大规模结构。这些数据和得出的数量（例如红移（z）和恒星质量），以及对FRB的测量（例如分散度量（DM）和旋转度量（RM））将实现三个主要的科学推力：（1）统计的统计确定Macquart Relation（Macquart Relation）的第一个统计确定（DM vs. Z），并引发了一个新的参数和新的参数。 （2）星系形成：推断银河晕圈中重子的径向分布，并限制沿着环境培养基的磁场和气体密度； （3）FRB祖细胞：测试许多模型来生产FRB，并在无线电，光学和X射线波长上使用快速的后续成像来解决FRB发射机制。该奖项反映了NSF的法定任务，并已通过评估该基金会的智力功能和广泛的影响来审查Criteria。
