Abstract:
We present our Spitzer-Infrared Spectrometer (IRS) spectroscopic
survey from 10um to 37um of the Seyfert galaxies of the 12um Galaxy
Sample (12MSG), collected in a high-resolution mode (R∼600). The new
spectra of 61 galaxies, together with the data we already published,
give us a total of 91 12um Seyfert galaxies observed, out of 112. We
discuss the mid-IR emission lines and features of the Seyfert
galaxies, using an improved active galactic nucleus (AGN)
classification scheme: instead of adopting the usual classes of
Seyfert 1's and Seyfert 2's, we use the spectropolarimetric data from
the literature to divide the objects into categories "AGN 1" and "AGN
2," where AGN 1's include all broad-line objects, including the
Seyfert 2's showing hidden broad lines in polarized light. The
remaining category, AGN 2's, contains only Seyferts with no detectable
broad lines in either direct or polarized spectroscopy. We present
various mid-IR observables, such as ionization-sensitive and
density-sensitive line ratios, the polycyclic aromatic hydrocarbon
(PAH) 11.25um feature and the H2S(1) rotational line equivalent
widths (EWs), the (60-25um) spectral index, and the source
extendedness at 19um, to characterize similarities and differences in
the AGN populations, in terms of AGN dominance versus star formation
dominance.
Description:
Most of the sample galaxies -the 29 galaxies presented in Paper I
(Tommasin et al., 2008ApJ...676..836T 2008ApJ...676..836T) and the 23 galaxies in this
paper- have been observed within the Spitzer Guaranteed Time Project
30291 (PI: Fazio). IRS high-resolution observations of another 37
objects, belonging to the 12MSG, were extracted from the Spitzer
Science Center (SSC) archive. The journal of the observations of the
61 galaxies presented here is shown in Table 1.

Note (1): Classification as follows:
HBLR = Seyfert with hidden broad-line regions (AGN 1).
non-HBLR = Seyfert with no detectable broad lines in either direct or
polarized spectroscopy (AGN 2).
non-BLR = Object for which there is no evidence of broad lines, but it lacks
polarization observations.
non-Sy = LINER, HII or starburst galaxies.
See section 2 for further details.
Note (2): Reference as follows:
1 = Data without off-source measurements;
2 = Data from Spitzer Archive;
3 = Data from P50253 to be released.
