TL;DR
This paper presents the third catalog of gamma-ray bursts detected by Swift's BAT over 11 years, including analyses of their temporal, spectral, and redshift properties, along with search results for pre- and post-burst emissions.
Contribution
It provides a comprehensive analysis and data release of BAT-detected GRBs, including new insights into ultra-long bursts and emission beyond standard event data.
Findings
15 ultra-long GRBs with emission beyond 1000 seconds
Only two GRBs detected in survey data before event data
Estimated false detection rate of one in the sample
Abstract
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. The result summaries and data products are available at http://swift.gsfc.nasa.gov/results/batgrbcat/index.html . In addition, we perform searches for GRB emissions before or after the event data using the BAT survey data. We estimate the false detection rate to be…
