Optical and Near-infrared Nebular-phase Spectroscopy of SN 2024ggi: Constraints on the Structure of the Inner Ejecta, Progenitor Mass, and Dust

We present optical and near-infrared (NIR) spectroscopic observations of the nearby Type II supernova SN 2024ggi ranging from 250 to 581 days after the explosion. Comparing the evolution of the [O i ] at 6300, 6363 Å doublet normalized to the continuum with spectral models from the literature, we es...
