To date, the Burst Alert Telescope (BAT) onboard Swift has detected ~ 1000 gamma-ray bursts (GRBs), of which ~ 360 GRBs have redshift measurements, ranging from z = 0.03 to z = 9.38. We present the analyses of the BAT-detected GRBs for the…

The Fermi Gamma-ray Burst Monitor (GBM) is designed to enhance the scientific return from Fermi in studying gamma-ray bursts (GRBs). In its first two years of operation GBM triggered on 491 GRBs. We summarize the criteria used for…

In this paper we look at \sim 10^14 eV neutrino bursts which are predicted to be observed in correlation with gamma ray bursts (GRBs). We describe an efficient way of constructing a km^2 effective area detector for these neutrino bursts.…
