Dear XMM-Newton helpdesk,

my name is Dr. Francesco Tombesi. I would like to report our recent XMM-Newton
results that may be interesting for a potential ESA press release.

Our work consisted in a uniform and systematic spectral analysis of a complete
sample of XMM-Newton observations of Radio-Quiet AGNs. Our main instruments were
the EPIC pn and the MOS. We detected blue-shifted Fe K absorption lines in more
than 35% of the sources, with velocities >10^4 km/s. These results confirm
the
presence of Ultra-fast Outflows (UFOs) in Radio-Quiet AGNs, possibly directly
connected with accretion disk winds/ejecta. The implications of this finding are
important for both the understanding of the black hole accretion physics and the
cosmological feedback.

The paper has been accepted for publication in Astronomy & Astrophysics and
can
be found in astro-ph:

We would like also to report another recent similar paper in which we discuss
the detection of UFOs also in a small sample of Radio-Loud AGNs observed with
Suzaku. This paper has been accepted for publication in The Astrophysical
Journal and can be found in astro-ph:

Mushotzky, R.~F.\ 2010, arXiv:1006.3536

I look forward to hearing from you.

Sincerely,

Francesco Tombesi

Dear Francesco Tombesi,

Thanks you very much for contacting us with a suggestion for
a potential ESA press release. I have already forwarded your
message to the Project Scientist who will contact you directly.

Regards,
   Matthias
