Wind-Fed GRMHD Simulations of Sagittarius A*: Tilt and Alignment of Jets and Accretion Discs, Electron Thermodynamics, and Multi-Scale Modeling of the Rotation Measure

Understand

Wind-fed models offer a unique way to form predictive models of the accretion flow surrounding Sagittarius A*.

• We present 3D, wind-fed MHD and GRMHD simulations spanning the entire dynamic range of accretion from parsec scales to the event horizon.
• We expand on previous work by including nonzero black hole spin and dynamically evolved electron thermodynamics.
• Initial conditions for these simulations are generated from simulations of the observed Wolf-Rayet stellar winds in the Galactic Centre.
