Abstract:
We construct full broad-band models in an analysis of Suzaku
observations of nearby Seyfert 1 active galactic nuclei (AGN) (z≤0.2)
with exposures >50ks and with greater than 30000 counts in order to
study their iron line profiles. This results in a sample of 46 objects
and 84 observations. After a full modelling of the broad-band Suzaku
and Swift-Burst Alert Telescope data (0.6-100keV), we find complex
warm absorption is present in 59 per cent of the objects in this
sample which has a significant bearing upon the derived FeK region
parameters. Meanwhile 35 per cent of the 46 objects require some
degree of high column density partial coverer in order to fully model
the hard X-ray spectrum. We also find that a large number of the
objects in the sample (22 per cent) require high velocity, high
ionization outflows in the FeK region resulting from FeXXV and
FeXXVI. A further four AGN feature highly ionized FeK absorbers
consistent with zero outflow velocity, making a total of 14/46 (30%)
AGN in this sample showing evidence for statistically significant
absorption in the FeK region.
Description:
The objects included within this sample are listed in Table 1 and are
all the Seyfert 1-1.9 AGN with exposures >50ks and greater than 30000
0.6-10.0keV counts which have been observed with Suzaku with data
publicly available in the Suzaku data archive
(http://heasarc.gsfc.nasa.gov/) as of 2011 September. We also include
data from some type 1 radio-loud (BLRGs - non-blazar) AGN, provided
they fit the above exposure and count criteria. High-energy X-ray data
from Swift-BAT from the 58-month BAT catalogue are also used in
addition to that obtained from the HXD detector on-board Suzaku (but
allowing the relative cross-normalization to vary), therefore the
total energy range covered is 0.6-100.0keV.
