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…

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…
