JWST NIRSpec Observations of Supernova 1987A—From the Inner Ejecta to the Reverse Shock

JWST NIRSpec Observations of Supernova 1987A—From the Inner Ejecta to the Reverse Shock

We present initial results from JWST NIRSpec integral field unit observations of the nearby supernova SN 1987A. The observations provide the first spatially resolved spectroscopy of the ejecta and equatorial ring (ER) over the 1–5 μ m range. We construct 3D emissivity maps of the [Fe i ] 1.443 μ m l...
