Abstract:

We observed 3EG J1234-1318 with the CANGAROO-II telescope in March, 2002. This source is a steady unidentified EGRET gamma-ray source at high Galactic latitude which has been associated with a dynamically merging clusters of galaxies, and is therefore a candidate TeV source. TeV gamma-ray emission is also expected as a result of large-scale cosmological structure formation. We here report the resulting upper limit on the TeV gamma-ray emission from 3EG J1234-1318.

Keywords: gamma-rays; clusters of galaxies; 3EG J1234-1318
