Caption: Figure 9.
The velocity, radius, temperature, and luminosity evolution of SN 2025kg’s fast cooling phase inferred from our cooling, expanding blackbody model with traces from the same fits as in Figure 8. The black lines in each panel indicate the evolution derived when using the median of each parameter (i.e., the values reported in Table 2). We also plot the properties inferred from our blackbody fits to our photometric epochs (circles) and spectroscopic continua (crosses).
