Correlative Spectral Analysis of Gamma-Ray Bursts using Swift-BAT and GLAST-GBM
We discuss the preliminary results of spectral analysis simulations involving anticipated correlated multiwavelength observations of gamma-ray bursts (GRBs) using Swifts Burst Alert Telescope (BAT) and the Gamma-Ray LargeArea Space Telescopes (GLAST) Burst Monitor (GLAST-GBM), resulting in joint spectral fits, including characteristic photon energy (Epeak) values, for a conservative annual estimate of~30 GRBs. The addition of BATs spectral response will (i)complement in-orbit calibration efforts of GBMs detector response matrices, (ii) augment GLASTs low energy sensitivityby increasing the ~ 20-100 keV effective area, (iii) facilitate ground-based follow-up efforts of GLAST GRBs by increasingGBMs source localization precision, and (iv) help identify a subset of non-triggered GRBs discovered via off-line GBMdata analysis. Such multi-wavelength correlative analyses, which have been demonstrated by successful joint-spectral fits ofSwift-BAT GRBs with other higher energy detectors such as Konus-WIND and Suzaku-WAM, would enable the study ofbroad-band spectral and temporal evolution of prompt GRB emission over three energy decades, thus potentially increasingscience return without placing additional demands upon mission resources throughout their contemporaneous orbital tenureover the next decade.
