Modeling the Accretion Flow Onset  in the Low-Luminosity AGN NGC3115

Abstract: The superb angular resolution of the Chandra satellite allows us to probe accretion flows in AGNs on scales comparable to the radius of the black hole (BH) gravitational influence (the “Bondi radius”). X-ray emission from the onset region of the accretion flow has recently been seen in a 1Ms X-ray visionary project (XVP) observation of NGC3115.  I discuss the theoretical modeling of those data with various solutions of gas dynamics. The BH is fed by stellar winds, most of which seem to accumulate in the feeding region,  rather than accreting onto the BH or outflowing.


This talk will be presented at the HETG Group meeting at 2pm in Marlar Lounge.
