The multifaceted Type II-L supernova 2014G from pre-maximum to nebular phase
We present multiband ultraviolet, optical, and near-infrared photometry, along with visual-wavelength spectroscopy, of supernova (SN) 2014G in the nearby galaxy NGC 3448 (25 Mpc). The early-phase spectra show strong emission lines of the high ionization species He ii/N iv/C iv during the first 2–3 d after explosion, traces of a …
