Physics

Scientific paper

We propose a 125 ksec observation of the hot gas around the supermassive black hole at the center of the S0 galaxy NGC3115 to confirm that the size of the Bondi radius is large enough to be resolved by Chandra in future deeper observations. We also seek to confirm that the temperature of the gas rises within the Bondi radius, as predicted by radiative inefficient accretion models. If confirmed, NGC3115 will represent the *only* opportunity to perform a detailed test of inefficient accretion flow theory in the Chandra era and the foreseeable future, and deeper Chandra observations will be proposed to map rho(R) and T(R) for the first time within the Bondi radius of a black hole. This observation will also provide the deepest look of the X-ray binary population of an S0 galaxy to date.
