Figure caption: Cumulative rate as a function of spectral energy. The empirical/observed cumulative rate for FRB 20250316A is shown as a solid green line. We show the 99.7% confidence intervals around the observed cumulative rate assuming Poisson statistics (green region). The single observed burst from FRB 20250316A is marked at its measured spectral energy (green star). Our sensitivity threshold (0.5 Jy ms) is shown with a green vertical dashed line. For comparison, we show the observed best-fit spectral energy functions for FRB 20201124A (F. Kirsten et al. 2024) and FRB 20220912A (O. S. Ould-Boukattine et al. 2024) with black dotted and dotted–dashed lines, respectively. Even scaling these observed overall rates down orders of magnitude, essentially as low as possible without making the observation of the first burst improbable (gray dotted and dotted–dashed lines for scaled-down cumulative rate distributions of FRB 20201124A and FRB 20220912A, respectively), reveals a significant dearth of lower-energy bursts compared to the expected rates, illustrating the tension between this burst and well-studied repeating FRBs.

Figure caption: Left: [O II] 3729/[O II] 3726 line-ratio map over the KCWI footprint. The flux ratios are only computed where the combined [O II] doublet emission is over the 3σ limit set by the background and where the line fluxes are measured (i.e., positive-amplitude Gaussian fit to the emission line). Other spaxels are blanked out. The 2σ FRB localization is marked by the white ellipse. Middle: the per-spaxel error in the flux-ratio measurement estimated from propagating the curve-fitting errors. Right: a histogram of line-ratio values from all the colored spaxels in the left frame (deep blue). The median value is 1.5 with a standard deviation of 0.2, although the distribution is clearly non-Gaussian, and most spaxels have a line ratio of 1.6. If we limit the histogram to spaxels where the flux error is below 0.25 (i.e., the blue-green regions in the middle panel), then the peak at 1.6 is no longer as prominent, but most spaxels still have a flux ratio consistent with low-density gas (≲1 e− cm−3). The FRB line ratio at the FRB location could be slightly lower, implying an enhanced density, but our measurement errors preclude a definitive gas-density estimate.

Figure caption: Strong-line metallicity diagnostics. Left: a map of R23 computed from the blue-arm data cube of KCWI. Middle: the [N II] 6584/Hα flux ratio estimated from the red-arm data cube. Given that most spaxels near the FRB location show [N II] 6584/Hα > 0.1, we can safely assume that the metallicity is higher than 8.1 and thus break the degeneracy in R23. Right: subsequently, we can invert the best-fit R23–﹩{\mathrm{log}}\,(Z/{Z}_{\odot })﹩ relation on the high-metallicity branch of the curve to produce a metallicity map near the FRB (2σ localization, shown by the black ellipse). We note that the FRB environment’s metallicity is only weakly subsolar.

Figure caption: Overview of the FRB 20250316A observing campaign for repeat bursts by HyperFlash, ÉCLAT, and CHIME/FRB for 2 months following the discovery of the as-yet-nonrepeating burst. FRB 20250316A’s time of arrival is denoted with a dotted black vertical line. Each colored block represents an observation with a telescope at a given frequency (y-axis). Prior to the period shown above, CHIME/FRB additionally observed the position of FRB 20250316A nearly each sidereal day for ∼11 minutes per transit since it commenced operations in 2018.

Figure caption: Residual dirty images of FRB 20250316A using the HSA (left) and EVN (right) at 4.9 GHz. The rms of each image is σ = 4.4 μJy beam−1 and σ = 9.2 μJy beam−1, respectively. Images are saturated to ±5σ. We overplot the 1σ, 2σ, and 3σ localization contours of the FRB as white ellipses, with the levels indicated on the image. We identify no evidence for compact radio emission in the field of FRB 20250316A, placing a 5σ upper limit on any PRS emission of ≤22 μJy.
