Abstract	LLAGN likely have radiatively-inefficient accretion flows (RIAFs) where at leastthe inner accretion disk is a spherical plasma while the outer regions may be ina standard geometrically-thin accretion disk. We propose to observe two of thebrightest LLAGN with NuSTAR and XMM-Newton. The NuSTAR data will provide, forthe first time, coverage of these sources up to 50 keV, and theNuSTAR+XMM-Newton broad band spectrum will allow for the measurement (or placingstringent constraints) on the high energy cutoff in these sources, allowing fora comparison to luminous AGN. Using the XMM-Newton OM, these data will providesimultaneous UV-X-ray SED that can be fit to RIAF models. All this will add tothe growing number of NuSTAR AGN and extend the hard X-ray properties to very low Eddington rates.

Mission Description	The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
