A Spectacular VHE Gamma-Ray Outburst from PKS 2155-304 in 2006
W. Benbow, C. Boisson, L. Costamante +10
Since 2002 the VHE (>100 GeV) gamma-ray flux of the high-frequency peaked BL Lac PKS 2155-304 has been monitored with the High Energy Stereoscopic System (HESS). An extreme gamma-r…
Multi-wavelength Observations of PG 1553+113 with HESS
HESS Collaboration, W. Benbow, C. Boisson +2
Very high energy (VHE; >100 GeV) gamma-ray observations of PG 1553+113 were made with the High Energy Stereoscopic System (HESS) in 2005 and 2006. A strong signal, ~10 standard dev…
Non-LTE Analysis of Lyman-Line Observations of a Filament with SUMER
P. Schwartz, B. Schmieder, P. Heinzel
We present non-LTE diagnostics of the filament observed by SOHO/SUMER on May 27, 2005 in the whole Lyman series. The filament was situated close to the disk center. The Ly_alpha ob…
X-ray powerful diagnostics for highly-ionized plasmas: He-like ions
D. Porquet, R. Mewe, J. S. Kaastra +2
The calculations of the ratios of the Helium-like ion X-ray lines from C V to Si XIII are revisited in order to apply the results to density, temperature and ionization process dia…
Modelling of the X-ray broad absorption features in Narrow-Line Seyfert 1s
D. Porquet, M. Mouchet, A. -M. Dumont
We investigate the origin of the broad absorption features detected near 1-1.4 keV in several Narrow Line Seyfert 1 galaxies, by modelling the absorbing medium with various physica…
