SN 2022acko and the Properties of Its Red Supergiant Progenitor: Direct Detection, Light Curves, and Nebular Spectroscopy

We present ultraviolet, optical, and infrared observations of the Type II-P supernova SN 2022acko in NGC 1300, located at a distance of 19.0 ± 2.9 Mpc. Our dataset spans 1–350 day postexplosion in photometry, complemented by late-time optical spectroscopy covering 200–600 days, and includes deep pre...
