The 230 GHz Variability of Numerical Models of Sagittarius A* II. The Physical Origins of the Variability

Ho-Sang Chan, Chi-kwan Chan

We continue our previous work, Chan et al. 2024, to investigate how variations in the electron temperature prescription parameter, $R_{Low}$ , influence the $3$ -hour variability…
