Hα emission lines in the late-time optical spectra of SN 2016jae. Left: comparison of SN 2016jae late-time optical spectra, along with those of the SNe 2018cqj and 2018fhw at similar epochs. All spectra were redshift and reddening corrected (values adopted from the literature; see also Table B.1). Ages are relative to B maximum light. The locations of the Hα emission line are also indicated. Right: decomposition of the Hα emission line of SN 2016jae at phases 84.0 (top) and 141.8 d (bottom). Three Gaussian profiles have been used, for the narrow Hα and the two broad components of iron-group elements.
