dc.description.abstract | We investigated the relation of mid-infrared (MIR) and radio emission for Narrow-Line
Seyfert 1 (NLSy1) galaxies, using the data from the Sloan Digital Sky Survey (SDSS),
the Wide-Field Infrared Survey Explorer (WISE), the Faint Images of the Radio Sky at
Twenty cm (FIRST), and the Swift X-Ray Telescope (XRT). We found that there is a
positive correlation between the 22m MIR (W4) and the 1.4GHz radio (FIRST) emission.
Besides, the correlation exists between the 22m MIR (W4) and the [O III] emission. Next,
we found that the 22m MIR (W4) is correlated with the black hole mass. However, we
could not find significant correlation between the 22m MIR (W4) and the X-ray emission.
Finally, we utilized a two-dimensional decomposition software, “GALFIT”, to decompose
the NLSy1 galaxies into bulge, disk and AGN components. Then, we found that the radio
emission is well correlated with the disk component brightness for the NLSy1, suggesting
that the radio emission might be related to the star formation activity. Nevertheless, the
MIR and the [O III] emission are related to the AGN. Our results suggest that most of
the MIR emission should be from the central AGN. | en_US |
