GA-NIFS: Witnessing the complex assembly of a massive star-forming system at z=5.7

We present observations of the z\sim5.7 Lyman-break galaxy HZ10 with the JWST/NIRSpec IFU in high and low spectral resolution (G395H, R\sim2700 and PRISM, R\sim100, respectively), as part of the GA-NIFS program. By spatially resolving the source, we find evidence for three spatially and spectrally distinct regions of line emission along... Show more
