The Red Sequence of High-Redshift Clusters: a Comparison with Cosmological Galaxy Formation Models

N. Menci, P. Rosati, R. Gobat +4

We compare the results from a semi-analytic model of galaxy formation with spectro-photometric observations of distant galaxy clusters observed in the range 0.8< z< 1.3. We investi…

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…

The precision of large radio continuum source catalogues- An application of the SPECFIND tool

B. Vollmer, E. Davoust, P. Dubois +3

The accuracy in position and flux density of 19 large radio continuum source catalogues has been determined using SPECFIND, a new tool recently made available through the CDS. The…

A method for determining radio continuum spectra, and its application to large surveys

B. Vollmer, E. Davoust, P. Dubois +3

A new tool to extract cross-identifications and radio continuum spectra from radio catalogues contained in the VIZIER database of the CDS is presented. The code can handle radio su…
