Abstract (from CDS):

We report the discovery of a dwarf Seyfert 1 active galactic nucleus (AGN) with a candidate intermediate-mass black hole, hosted by the dwarf galaxy SDSS J160531.84+174826.1 at z=0.032. A broad component of the Hα line with FWHM=781 km/s is detected in its optical spectrum, and a bright, pointlike nucleus is evident from a Hubble Space Telescope (HST) imaging observation. Nonthermal X-ray emission is also detected from the nucleus. The black hole mass, as estimated from the luminosity and width of the broad Hα component, is about 7x104 M. The host galaxy appears to be a disk galaxy with a boxy bulge or nuclear bar. With an absolute magnitude of MR=-17.8 (MB=-16.4), it is among the least luminous host galaxies ever identified for a Seyfert 1.
