M94 as a Unique Testbed for Black Hole Mass Estimates and AGN Activity at Low Luminosities
Figure 4
Radio to X-ray nuclear SED of NGC 4736 superposed on SEDs of LLAGN from Ho [47]. The optical STIS spectrum stands out as an amorphous blob featuring the strong emission feature. The 2–10 keV Chandra X-ray detection X2 is depicted as a power-law corresponding to . The low spatial resolution Spitzer IRS observations are shown for comparison.
