Scientific paper

How inefficient can black hole accretion be? To answer this question, we propose a 60ks observation of Maffei 1, the nearest major elliptical galaxy. Our principal goal is to search for low-level nuclear activity - we will be sensitive to nuclear activity with luminosities as low as 10^-7 of the naive radiatively-efficient Bondi luminosity. Failing to detect nuclear activity will strongly constrain theoretical models of black hole accretion, requiring models that effectively starve the mass flow rate. We will also probe the discrete X-ray source population down 2*10^36erg/s. In particular, we will determine the X-ray properties of the recently studied globular cluster population of Mf1.
