IMPROVING THE LOCALIZATION OF GBM GRBS WITH SWIFT/BAT EVENT DATA

Project: Research project

Project Details

Description

WE SEEK TO IMPROVE THE LOCALIZATION OF FERMI/GBM DETECTED GRBS. UTILIZING GBM S SWIFT IS COMMANDED TO DUMP BAT EVENT DATA USUALLY DISCARDED ON BOARD TO THE GROUND. THESE DATA WILL BE ANALYZED FOR EVIDENCE OF A CO-DETECTION OF THE GRB BY BAT. IF DETECTED THEN WE WILL UTILIZE BAT DATA EITHER TO LOCALIZE THE GRB TO $/SIM$ARC-MINUTE RESOLUTION (IF WITHIN BAT FOV) OR IF OUTSIDE THE BAT CODED FOV COMBINE INFORMATION FROM GBM AND BAT TO SIGNIFICANTLY REDUCE THE GBM ERROR REGION. WE ESTIMATE OBTAINING ARCMINUTE LOCALIZATIONS FOR 15 GBM GRBS PER YEAR IN ADDITION TO THOSE CO-DETECTED BY BAT AND MANY MORE WILL ALLOW US TO SIGNIFICANTLY REDUCE THE GBM ERROR REGION. THIS IS VITALLY IMPORTANT FOR FUTURE MULTI-MESSENGER DETECTIONS OF NS MERGERS BY GBM AND THE GW DETECTOR NETWORK.
