Modeling Emission of Jet/Accretion Flow/Black Hole (JAB) Systems in GRMHD

Introduction:

• Modeling emission in jet/accretion flow/black hole (JAB) systems is a crucial part of understanding the dynamics behind active galactic nuclei.

• An established emission model emulating turbulent heating, the R-β Model, expresses the ion-to-electron temperature R as a function of plasma beta.

• Our alternative Critical β Model has an exponential transition from preferential electron to proton heating as a function of β; Our inclusion of magnetic-to-particle energy reconnection based emission in jet regions for both turbulent heating models are key advances in JAB emission model accuracy.

• We look at two distinct flow states for the accreting plasma: standard and normal evolution (SANE) and magnetically arrested disk (MAD).

• We model two large, well-studied Event Horizon Telescope (EHT) targets (M87 and Sgr A*), to create a pattern of emission properties and compare with observational evidence.
