Turatto (INAF OAPd) Padova-Asiago SN Ia 0.058 1 Padova-Asiago The best match of ASAS-SN18ao is with Type Ia SNe around maximum light. Assuming a redshift of 0.058, derived from SNID and GELATO spectral fitting and in agreement with the photoZ (0.063) of the host galaxy from SDSS14, an expansion velocity of about 10900 km/s is derived from the Si II 635.5 nm absorption. 2024TNSCR.899....1T
