A graphic titled “Fast Radio Burst Host Galaxy; Most Distant Fast Radio Burst; NIRSpec Integral Field Spectroscopy.” A graph plots brightness of light versus wavelength. The y axis is labeled brightness with an up arrow labeled brighter and a down arrow labeled dimmer. The x axis is labeled “Wavelength of Light, microns” and goes from 1.0 to 5.0 with tickmarks every 0.5 microns. A jagged white line slopes downward from left to right between 1.0 and 2.5 microns, and is mostly flat beyond that. A
