Low-Mass AGNs in the Local Universe

Joan M. Wrobel, National Radio Astronomy Observatory

Black holes grow via accretion and merging.  Accretion onto black
holes produces the electromagnetic signatures of active galactic
nuclei (AGNs).  Mergers of binary black holes produce gravitational
wave signatures, and LISA will be especially sensitive to binaries
with total masses of order 100,000 Solar masses.  Such low-mass black
holes are currently observed only as AGNs in the local universe.  The
properties of these low-mass AGNs will be summarized, with an emphasis
on their suitability as targets for the EVLA, ALMA and VLBA.
