Our group has used the High Energy Transmission Gratings (HETG) on board the Chandra X-ray telescope to perform deep, high-resolution spectroscopic observations of the Low Luminosity Active Galactic Nuclei (LLAGN) M81*. Along with these X-ray spectroscopic observations, we performed a series of simultaneous and near simultaneous radio observations. M81* is of particular interest because of its low fractional Eddington luminosity. It may represent an Advection Dominated Accretion Flow. Thus we discuss models where the emission is from a hot, inflowing plasma. It is also of interest because of its radio emission from a jet, which in some ways is similar to the even lower luminosity Galactic Center source, Sgr A*. It has been hypothesized the ...
