| 摘要 | 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 H alpha line with FWHM = 781 km s(-1) 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 H alpha component, is about 7 x 10(4) M.. The host galaxy appears to be a disk galaxy with a boxy bulge or nuclear bar. With an absolute magnitude of M-R = -17.8 (M-B = -16.4), it is among the least luminous host galaxies ever identified for a Seyfert 1. |
