The Third Swift Burst Alert Telescope Gamma-Ray Burst Catalog

Understand

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 past ~ 11 years up through GRB151027B.
• We report summaries of both the temporal and spectral analyses of the GRB characteristics using event data (i.e., data for each photon within approximately 250 s before and 950 s after the BAT trigger time), and discuss the instrumental sensitivity and selection effects of GRB detections.
• We also explore the GRB properties with redshift when possible.
