JWST NIRSpec spectroscopy of the triply-lensed z = 10.17 galaxy MACS0647-JD

We present JWST/NIRSpec prism spectroscopy of MACS0647-JD, the triply-lensed z \sim 11 candidate discovered in HST imaging and spatially resolved by JWST imaging into two components A and B. Spectroscopy of component A yields a spectroscopic redshift z=10.17 based on 7 detected emission lines: CIII] \lambda\lambda1907,1909, [OII] \lambda3727, [NeIII] \lambda3869,... Show more
