We propose HST mid-cycle imaging of the host galaxy of a fast radio burst (FRB) localized to milliarcsecond precision to constrain the origin of this enigmatic comma highly active comma repeating burst. Recent publications (based on HST observations) have established that FRBs occur primarily in star-forming galaxies with galactocentric offsets ranging from virgul1 to 10 kpc. These data also indicate a high incidence of spiral arm structure in the near-IR band and suggest the frequent appearance of FRBs within these arms. With deep WFC3-UVIS 475X images we will observe the host of FRB 20201124A to precisely measure its spiral arm structure and to add to the quantitative assessment of the distribution of FRB progenitor locations relative to the arms. Following similar studies on other transients (e.g. supernovae) comma our experiment will yield new constraints on FRB progenitor channels by establishing the relationship of FRBs to recent star-formation and their progenitor lifetimes comma using the high-resolution HST imaging in conjunction with VLA imaging of radio emission (presumed associated to recent star formation). The proposed observations with deep HST-WFC3 F160W will also determine the morphology comma galactocentric offset comma radial light distribution and local measure of the stellar mass surface density. The observations will utilize HST.s high angular resolution imaging and UV sensitivity to measure the immediate galactic environment of this FRB and the nature of star formation to within a single pixel (0.1 kpc) of the burst.s origin. We commit to rapid publication and release of the data to guide future research of this unique source.
