Exploring Black Hole Accretion Through Multidimensional Simulations
Year: 2025
Type: article
Abstract: Our ability to electromagnetically detect and characterize astrophysical black holes depends crucially on their accretion of gas. We used the Eulerian grid codes FLASH, Athena, and Athena++ to perform fluid dynamic simulations, studying black hole accretion. Our findings demonstrate that, in viscous conditions, all three codes produce similar accretion rates, while, in non-viscous conditions, Athena++ appears to generate much smaller accretion rates. Nevertheless, our results give insight on the purely numerical variability of black hole accretion.
