We put active galactic nuclei (AGNs) with low-mass black holes on the fundamental plane of black hole accretion-the plane that relates X-ray emission, radio emission, and mass of an accreting black hole-to test whether or not the relation is universal for both stellar-mass and supermassive black holes. We use new Chandra X-ray and Very Large Array radio observations of a sample of black holes with masses less than 10(6.3) M-circle dot, which have the best leverage for determining whether supermassive black holes and stellar-mass black holes belong on the same plane. Our results suggest that the two different classes of black holes both belong on the same relation. These results allow us to conclude that the fundamental plane is suitable for use in estimating supermassive black hole masses smaller than similar to 10(7) M-circle dot, in testing for intermediate-mass black holes, and in estimating masses at high accretion rates.
