CANGAROO-III Observations of the supernova remnant RX J0852.0$-$4622

Abstract

Sub-TeV gamma-ray emission from the North-West rim of the supernova remnant RX J0852.0$-$4622 was detected with the CANGAROO-II telescope and recently confirmed by the H.E.S.S. group. In addition, the H.E.S.S. data revealed a very wide (up to two degrees in diameter), shell-like profile of the gamma-ray emission. We have carried out CANGAROO-III observations in January and February 2005 with three telescopes and show here the results of three-fold coincidence data. We confirm the H.E.S.S. results about the morphology and the energy spectrum, and find the energy spectrum in the NW-rim is consistent with that of the whole remnant.
