"Warm absorbers" and "-mirrors": one and the same gas?
Matteo Guainazzi, Stefano Bianchi
We review the main properties of "warm mirrors" in obscured AGN, and discuss whether the scattering gas could be also responsible for "warm absorbers" commonly observed in unobscur…
The properties of unobscured AGN observed by XMM-Newton
Stefano Bianchi, Matteo Guainazzi, Giorgio Matt +1
Multiwavelength analysis on large samples of AGN provides an excellent tool to understand the physics of these objects. We present the largest catalog of XMM-Newton targeted AGN, a…
Search for narrow energy-shifted lines in XMM-Newton AGN spectra
A. L. Longinotti, S. Bianchi, M. Guainazzi +2
The detection of X-ray narrow spectral features in the 5-7 keV band is becoming increasingly more common in AGN observations, thanks to the capabilities of current X-ray satellites…
The XMM-Newton/INTEGRAL monitoring campaign of IGR J16318-4848
A. Ibarra, G. Matt, M. Guainazzi +5
IGR J16318-4848 is the prototype and one of the more extreme examples of the new class of highly obscured Galactic X-ray sources discovered by INTEGRAL. A monitoring campaign on th…
The nature of the soft X-ray emission in obscured AGN
Stefano Bianchi, Matteo Guainazzi
The origin of the soft X-ray emission in obscured AGN is still largely unknown. However, important progresses have been made thanks to the high energy and spatial resolution of XMM…
X-ray obscuration in local Universe AGN
Matteo Guainazzi
I review the constraints that X-ray observations impose on the physical properties and the geometrical distribution of cold absorbing gas in nearby obscured Active Galactic Nuclei…
