This study explores the implications of joint spectral analysis using data from Fermi's Gamma-ray Burst Monitor (GBM), Large Area Telescope (LAT), and LAT Low Energy (LLE) on phenomenological correlations in Gamma-Ray Bursts (GRBs). Combining spectral data from these three Fermi instruments, we aim to enhance our understanding of GRB characteristics and their potential as cosmological probes....

Since the first detection of Gamma-ray Bursts (GRBs) in 1967, GRBs have been an active subject of study with many questions still left unanswered. In particular, the dominant radiation mechanism responsible for the prompt emission of GRBs remains an open question. As the host of possible GRB prompt emission models grows it has become clear that relying on spectral information alone to discern...

The recent detection of very high-energy gamma-ray emission (VHE, $>$ 100 GeV) from a subset of gamma-ray bursts (GRBs) has opened new opportunities for GRB research. The temporal and spectral evolution of VHE GRB afterglows requires comprehensive modeling and high-cadence, multi-wavelength observations across the electromagnetic spectrum (radio to VHE). Standard afterglow emission from VHE...
