Evidence for ultra-fast outflows in radio-quiet AGNs: II - detailed photo-ionization modeling of Fe K-shell absorption lines
F. Tombesi, M. Cappi, J. N. Reeves +3
X-ray absorption line spectroscopy has recently shown evidence for previously unknown Ultra-fast Outflows (UFOs) in radio-quiet AGNs. In the previous paper of this series we define…
First high-resolution detection of a warm absorber in the Broad Line Radio Galaxy 3C 382
E. Torresi, P. Grandi, A. L. Longinotti +4
Recent high-resolution measurements suggest that the soft X-ray spectrum of obscured Radio Galaxies (RG) exhibits signatures of photoionised gas (e.g. 3C 445 and 3C 33) similar to…
X-ray evidence for a mildly relativistic and variable outflow in the luminous Seyfert 1 galaxy Mrk509
M. Cappi, F. Tombesi, S. Bianchi +9
There is growing evidence for the presence of blueshifted Fe K absorption lines in a number of radio-quiet AGNs and QSOs. These may be fundamental to probe flow dynamics near super…
On the Simbol-X capability of detecting red/blue-shifted emission and absorption Fe K lines
F. Tombesi, M. Cappi, G. Ponti +2
The detection of red/blue-shifted iron lines in the spectra of astronomical X-ray sources is of great importance, as it allows to trace the environment around compact objects, like…
Variability of the Fe K line relativistic component in a sample of Seyfert 1 galaxies
B. De Marco, M. Cappi, M. Dadina +1
We present the analysis of X-ray spectral varability made on a sample of 7 Seyfert 1 bright galaxies, using XMM-Newton data. From the "XMM-Newton Science Archive" we selected those…
INTEGRAL observations of the field of the BL Lacertae object S5~0716+714
E. Pian, L. Foschini, V. Beckmann
We have performed observations of the blazar S5 0716+714 with INTEGRAL on 2-6 April 2004. In the first months of 2004, the source had increased steadily in optical brightness and h…
