An internal shock model calibrated with real gamma-ray burst light curves using a genetic algorithm
Manuele Maistrello, Cristiano Guidorzi, Shiho Kobayashi +1
The paper calibrates an internal shock model for gamma‑ray burst prompt emission by using a genetic algorithm to match simulated light curves to observed data from Swift, Fermi, an…
The Origin of Cross-Energy-Similar FRED Profiles in Gamma-Ray Bursts Pulses
Shu-Xu Yi, Chen-Wei Wang, Shao-Lin Xiong +5
To understand the physical mechanisms underlying the prompt emission of gamma-ray bursts (GRB), single FRED (Fast-Rise-Exponential-Decay) profile GRBs serve as an ideal sample, as…
The hidden population of long gamma-ray bursts from compact object mergers
R. Maccary, C. Guidorzi, L. Amati +6
Context. The prompt-emission time profiles of GRB 230307A and other long-duration compact object merger (COM) candidates exhibit a unique set of temporal properties, characterised…
FAST-MEPSA: an optimised and faster version of peak detection algorithm MEPSA
Manuele Maistrello, Romain Maccary, Cristiano Guidorzi
We present FAST-MEPSA, an optimised version of the MEPSA algorithm developed to detect peaks in uniformly sampled time series affected by uncorrelated Gaussian noise. Although orig…
GRB X-ray plateaus as evidence that the afterglow begins before the prompt gamma-ray emission
C. Guidorzi, R. Maccary, M. Maistrello +3
Most GRB X-ray afterglow light curves are characterised by a plateau, followed by a normal power-law decay interpreted as afterglow emission. Despite the numerous alternative inter…
A set of distinctive properties ruling the prompt emission of GRB 230307A and other long γ-ray bursts from compact object mergers
R. Maccary, C. Guidorzi, M. Maistrello +9
Short gamma-ray bursts (SGRBs), occasionally followed by a long and spectrally soft extended emission, are associated with compact object mergers (COMs). Yet, a few recent long GRB…
