The very large collection area of ground-based γ-ray telescopes gives them a substantial
advantage over balloon or satellite based instruments in the detection of very-high-energy (> …

The measurement of an excess in the cosmic-ray electron spectrum between 300 and 800
GeV by the ATIC experiment has – together with the PAMELA detection of a rise in the …

Aims.To investigate the very high energy (VHE: >100 GeV) γ-ray emission from the high-frequency
peaked BL Lac 1ES 0229+200.Methods.Observations of 1ES 0229+200 at energies …

Starburst galaxies exhibit in their central regions a highly increased rate of supernovae, the
remnants of which are thought to accelerate energetic cosmic rays up to energies of ~10 15 …

Context.The detection of gamma rays in the very-high-energy (VHE) energy range (100 GeV–100
TeV) provides a direct view of the parent population of ultra-relativistic particles found …

▪ Abstract Epithelial morphogenesis comprises the various processes by which epithelia
contribute to organ formation and body shape. These complex and diverse events play a central …

Aims. Recent theoretical predictions of the lowest very high energy (VHE) luminosity of SN
1006 are only a factor 5 below the previously published HESS upper limit, thus motivating …

Aims. A detailed study of the spectrum and variability of the source HESS J1745-290 in the
Galactic Center (GC) region using new data from the HESS array of Cherenkov telescopes is …

An algorithm is presented, that provides a fast and robust reconstruction of neutrino induced
upward-going muons and a discrimination of these events from downward-going …

Myofibril assembly results in a regular array of identical sarcomeres in striated muscle.
Sarcomere structure is conserved across the animal kingdom, which implies that the mechanisms …
