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…
NLTE determination of the sodium abundance in a homogeneous sample of extremely metal-poor stars
S. M. Andrievsky, M. Spite, S. A. Korotin +5
Abundance ratios in extremely metal-poor (EMP) stars are a good indication of the chemical composition of the gas in the earliest phases of the Galaxy evolution. It had been found…
