Radiatively inefficient accretion disks in low luminosity AGN
Marco Chiaberge
Emission from radiatively inefficient accretion flows (RIAFs) is often
swamped by other radiation processes. We studied local samples of
LLAGN, from the least luminous LINERs to low power radio galaxies.
Using HST we can disentangle the faint nuclear sources associated with
either the accretion process or ejection of matter from the vicinity
of the black holes. Our results give us a powerful tool to find
objects in which RIAFs can be detected.
