Probing the unified model in NGC 7314
  We present a study of the complex absorbed X-ray spectrum of the Narrow Line
Seyfert 1 galaxy NGC 7314. We collected available public X-ray data from the
archives of XMM-Newton, Suzaku, and ASCA. The spectra were analyzed using the
fitting package SPEX. We find evidence of intrinsic neutral and ionized
absorption in the XMM-Newton EPIC-pn spectrum. The ionized gas presents three
significantly distinct ionization phases, although its kinematic properties
could not be disentangled. At least two of these phases are also detected in
the RGS spectrum, although with less significance due to the low statistics.
The ASCA and Suzaku spectra show larger neutral absorption but no ionized gas
signatures. The Fe Kalpha emission line is detected in all the observations
and, additionally, Fe XXVI in the EPIC-pn spectrum, and Fe Kbeta in the Suzaku
XIS spectrum. Using this observational evidence we construct a consistent
picture of the geometry of the system in the context of the unified model of
active galactic nuclei. The different observational properties are thus
interpreted as clouds of neutral gas moving across our line of sight, which
would be grazing a clumpy dusty torus.
