The source HESS J1813-178 has sparked particular interest, as subsequent radio observations imply an association with supernova remnant G12.82-0.02. Triggered by the detection in very high energy gamma-rays, a positionally coincident source has also been found in INTEGRAL and ASCA data. In this Letter we present MAGIC observations of HESS J1813-178, resulting in the detection of a differential gamma-ray flux consistent with a hard-slope power law, described as dN(gamma)/(dA dt dE) = (3.3 +/- 0.5) x 10(-12)(E/TeV)(-2.1 +/- 0.2) cm(-2) s(-1) TeV-1. We briefly discuss the observational technique used and the procedure implemented for the data analysis, and we put this detection in the perspective of multifrequency observations. eng open access MAGIC observations of very high energy gamma-rays from HESS J1813-178 journal article
