Abstract:
We investigated the connection between the mid-infrared (MIR) and
optical spectral characteristics in a sample of 82 Type 1 active
galactic nuclei (AGNs), observed with Infrared Spectrometer on Spitzer
(IRS) and Sloan Digital Sky Survey (SDSS, DR12). We found several
interesting correlations between optical and MIR spectral properties:
(i) as starburst significators in MIR increase, the equivalent widths
(EWs) of optical lines HβNLR and FeII, increase as well; (ii)
as MIR spectral index increases, EW([OIII]) decreases, while
fractional contribution of AGN (RAGN) is not connected with
EW([OIII]); (iii) The log([OIII]5007/HβNLR) ratio is weakly
related to the fractional contribution of polycyclic aromatic
hydrocarbons (RPAHs). We compare the two different MIR and optical
diagnostics for starburst contribution to the overall radiation (RPAH
and Baldwin, Philips & Terlevich diagram, respectively). The
significant differences between optical and MIR starburst diagnostics
were found. The starburst influence to observed correlations between
optical and MIR parameters is discussed.
Description:
We investigate the optical and MIR spectral properties of a sample of
82 Type 1 AGNs. Additionally, to check the results based on the narrow
lines (which are superposed with broad lines in the Type 1 AGNs), we
considered a sample of 49 Type 2 AGNs.
