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…
The Panchromatic Afterglow of GW170817: The full uniform dataset, modeling, comparison with previous results and implications
Sphesihle Makhathini, Kunal P. Mooley, Murray Brightman +35
We present the full panchromatic afterglow light curve data of GW170817, including new radio data as well as archival optical and X-ray data, between 0.5 and 940 days post-merger.…
The Rates of Hypernovae and Gamma-Ray Bursts: Implications for their Progenitors
Ph. Podsiadlowski, P. A. Mazzali, K. Nomoto +2
A critical comparison of estimates for the rates of hypernovae (HNe) and gamma-ray bursts (GRBs) is presented. Within the substantial uncertainties, the estimates are shown to be q…
X-ray spectral diagnostics of the immediate environment of GRB 991216
D. R. Ballantyne, E. Ramirez-Ruiz, D. Lazzati +1
The recent report of iron line features in the afterglow of the gamma-ray burst (GRB) 991216 has important implications for the properties of the radiating material and hence the n…
Afterglow lightcurves, viewing angle and the jet structure of gamma-ray bursts
E. Rossi, D. Lazzati, M. J. Rees
Gamma ray bursts are often modelled as jet-like outflows directed towards the observer; the cone angle of the jet is then commonly inferred from the time at which there is a steepe…
