Comparison of the B-band light-curve decline rate and the absolute maximum magnitude for a sample of SNe Ia. SN 2024igg is emphasized as a red triangle. Normal SNe Ia from the Pantheon samples (Scolnic et al. 2018) are shown as gray dots. The solid black curve represents the best-fit Lira-Phillips relation. The 03fg-like sample, shown as blue triangles, is taken from Ashall et al. (2021) except for SNe 2009dc (Taubenberger et al. 2011), 2020esm (Dimitriadis et al. 2022), 2020hvf (Jiang et al. 2021), and 2021zny (Dimitriadis et al. 2023).
