Abstract

The Suzaku Wide-band All-sky Monitor (WAM), realized by large thick anti-coincidence shields of the Hard X-ray Detector (HXD), can be powerful gamma-ray burst (GRB) detector which is sensitive to 50-5000 keV gamma-rays. The WAM is now in a full operational phase, and we have already detected some GRBs simultaneously with other satellites (Swift, Konus-Wind, HETE2 and INTEGRAL SPI/ACS). The most impressive event among detected GRBs is GRB051008, which was detected up to 2 MeV with the WAM. In this paper, we report on the WAM in-flight performance as a GRB monitor from initial three-months operations, focusing on the GRB trigger status and spectral analysis of GRB051008 and GRB051111 combined with Swift.
