A northern sky survey for steady point sources of ultra-high energy gamma-rays with KASCADE — Zhaoyang Feng und •Donghwa Kang für die KASCADE-Grande Kollaboration — Karlsruher Institut für Technologie

In KASCADE, extensive air showers with primary energies around 300 TeV can be measured with an EAS array consisting of large area electron detectors and muon detectors. Using the data taken between May 1998 and May 2010, a search for steady point sources in the northern hemisphere is performed using the equi-zenith method. In addition, a subset of muonless events, i.e., extensive air showers with no detected muons, are analyzed. No significant excess for a point source has been observed. The analysis results, as well as an upper limit for a steady point source will be presented.
