Abstract:
In this paper we analyze the X-ray, UV and optical data of the Seyfert
1.5 galaxy 1H0419-577, with the aim of detecting and studying an
ionized-gas outflow. The source was observed simultaneously in the
X-rays with XMM-Newton and in the UV with HST-COS. Optical data
were also acquired with the XMM-Newton Optical Monitor. We detected
a thin, lowly ionized warm absorber (logxi∼0.03, logNH∼19.9cm-2) in
the X-ray spectrum, consistent to be produced by the same outflow
already detected in the UV. Provided the gas density estimated in the
UV, the outflow is consistent to be located in the host galaxy, at
∼kpc scale. Narrow emission lines were detected in the
X-rays, in the UV and also in the optical spectrum. A single
photoionized-gas model cannot account for all the narrow lines
emission, indicating that the narrow line region is probably a
stratified environment, differing in density and ionization. X-ray
lines are unambiguously produced in a more highly ionized gas phase
than the one emitting the UV lines. The analysis suggests also that
the X-ray emitter may be just a deeper portion of the same gas layer
producing the UV lines. Optical lines are probably produced in
another, disconnected gas system. The different ionization condition,
and the ∼pc scale location suggested by the line width for
the narrow lines emitters, argue against a connection between the warm
absorber and the narrow line region in this source.
Description:
We provide the X-ray spectrum of 1H0419-577, obtained with the
XMM-Newton RGS (Reflection Grating Spectrometer). The data were taken
in two subsequent XMM-Newton observations, (respectively on 30/05/2010
and on 28/05/2010) for a total exposure time of 150ks. We provide
the fluxed spectrum and the correspondent spectral response matrix,
resulting from the combination of the the two datasets.
