Exploring GRB Astrophysics via a Correlated Broad-Band and Multi-Messenger Paradigm

I will present various results based upon a synergistic methodology whose primary objective encompasses probing discrete gamma-ray burst (GRB) high-energy particle astrophysics via a broad-band, multi-messenger paradigm. The interface between leptonic and electromagnetic emission will be explored using the theoretical interpretation and correlative observations of high energy telescopes such as (i) Swift's Burst Alert Telescope (BAT), (ii) the Gamma-Ray Large Area Space Telescope (GLAST) Burst Monitor (GBM) and (iii) IceCube. Multi-wavelength analysis results include evidence for temporal and spectral evolution in GRB 060218, in the context of the lag-luminosity relation, and simulation studies of joint photon energy spectra using Swift-BAT and GLAST-GBM. Lastly, a case study modeling the correlated (TeV-PeV) muon neutrino flux from GRB 030329, in the context of the canonical fireball henomenology, and its implications for neutrino astronomy are discussed.
