A JWST Near- and Mid-infrared Nebular Spectrum of the Type Ia Supernova 2021aefx

A JWST Near- and Mid-infrared Nebular Spectrum of the Type Ia Supernova 2021aefx

We present JWST near-infrared (NIR) and mid-infrared (MIR) spectroscopic observations of the nearby normal Type Ia supernova (SN) SN 2021aefx in the nebular phase at +255 days past maximum light. Our Near Infrared Spectrograph (NIRSpec) and Mid Infrared Instrument observations, combined with ground-...
