Nebular spectroscopy of SN 2014J: Detection of stable nickel in near-infrared spectra

We present near-infrared (NIR) spectroscopy of the nearby supernova 2014J obtained ∼450 d after explosion. We detect the [Ni II] 1.939 μm line in the spectra indicating the presence of stable 58Ni in the ejecta. The stable nickel is not centrally …
