Resum

Recently, the HESS array has reported the detection of γ-ray emission above a few hundred GeV from eight new sources located close to the Galactic plane. The source HESS J1834-087 is spatially coincident with the supernova remnant G23.3-0.3 (W41). Here we present MAGIC observations of this source, resulting in the detection of a differential γ-ray flux consistent with a power law, described as dNγ/(dA dt dE) = (3. 7 ± 0.6) × 10-12(E/TeV)-2.5±0.2 cm-2 s-1 TeV-1. We confirm the extended character of this flux. We briefly discuss the observational technique used and the procedure implemented for the data analysis, and we put this detection in the perspective of the molecular environment found in the region of W41. We present 13CO and 12CO emission maps showing the existence of a massive molecular cloud in spatial superposition with the MAGIC detection. © 2006. The American Astronomical Society.
