Modelling of Long-Term Afterglow Counterparts to Gravitational Wave Events: The Full View of GRB 170817A

Geoffrey Ryan, Hendrik van Eerten, Eleonora Troja +3

The arrival of gravitational wave astronomy and a growing number of time-domain focused observatories are set to lead to a increasing number of detections of short gamma-ray bursts…

Scaling relations for gamma-ray burst afterglow light curves and centroid motion independent of jet structure and dynamics

Hendrik van Eerten, Geoffrey Ryan

Models for gamma-ray burst afterglow dynamics and synchrotron spectra are known to exhibit various scale invariances, owing to the scale-free nature of fluid dynamics and the power…

Potential biases and prospects for the Hubble constant estimation via electromagnetic and gravitational-wave joint analyses

Giulia Gianfagna, Luigi Piro, Francesco Pannarale +3

GW170817 is a binary neutron star merger that exhibited a gravitational wave (GW) and a gamma-ray burst, followed by an afterglow. In this work, we estimate the Hubble constant ($H…

The ultra-long GRB 220627A at z=3.08

S. de Wet, L. Izzo, P. J. Groot +19

GRB 220627A is a rare burst with two distinct gamma-ray emission episodes separated by almost 1000 s that triggered the Fermi Gamma-ray Burst Monitor twice. High-energy GeV emissio…

A structured jet explains the extreme GRB 221009A

B. O'Connor, E. Troja, G. Ryan +29

Long duration gamma-ray bursts (GRBs) are powerful cosmic explosions, signaling the death of massive stars. Among them, GRB 221009A is by far the brightest burst ever observed. Due…
