Photospheric Prompt Emission From Long Gamma Ray Burst Simulations -- III. X-ray Spectropolarimetry
Tyler Parsotan, Davide Lazzati
While Gamma Ray Bursts (GRBs) have the potential to shed light on the astrophysics of jets, compact objects, and cosmology, a major set back in their use as probes of these phenome…

Single-Pulse Gamma-Ray Bursts have Prevalent Hard-to-Soft Spectral Evolution
Ian Busby, Davide Lazzati
We analyze the spectral evolution of 62 bright Fermi gamma-ray bursts with large enough signal to noise to allow for time resolved spectral analysis. We develop a new algorithm to…
