The variable ionized absorber in the Seyfert 2 Mrk 348
  We present the results of the analysis of the X-ray spectrum of the Seyfert 2
Mrk 348, observed by Suzaku and XMM-Newton. The overall spectrum of Mrk 348 can
be described by a primary power law continuum seen through three layers of
absorption, of which one is neutral and two are ionised. Comparing Suzaku
(2008) and XMM-Newton (2002) observations we find variability of the X-ray
spectral curvature. We suggest that the variability can be explained through
the change of column density of both the neutral and one of the ionised
absorbers, together with a variation of the ionisation level of the same
absorber. We thus confirm one of the main features presented in past works,
where intrinsic column density variability up to $\sim 10^{23}$~cm$^{-2}$ was
observed on time scales of months. We also find that the photon index of the
underlying power law continuum ($\Gamma \sim 1.8$) is in agreement with the
previous observations of this Seyfert 2.
