Observational Constraints on Direct Electron Heating in the Hot Accretion Flows in Sgr A* and M87*
An important parameter in the theory of hot accretion flows around black holes is δ , which describes the fraction of “viscously” dissipated energy in the accretion flow that goes directly into heating electrons. For a given mass accretion rate, the radiative efficiency of a hot accretion flow is de...
