GRB220831A: a hostless, intermediate Gamma-ray burst with an unusual optical afterglow
James Freeburn, Brendan O'Connor, Jeff Cooke +20
GRB220831A is a gamma-ray burst (GRB) with a duration and spectral peak energy that places it at the interface between the distribution of long-soft and short-hard GRBs. In thi…
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…
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…
A lanthanide-rich kilonova in the aftermath of a long gamma-ray burst
Yu-Han Yang, Eleonora Troja, Brendan O'Connor +24
Observationally, Kilonovae are astrophysical transients powered by the radioactive decay of nuclei heavier than iron, synthesized in the merger of two compact objects. Over the fir…
The Decoupling of Binaries from Their Circumbinary Disks
Alexander J. Dittmann, Geoffrey Ryan, M. Coleman Miller
We have investigated, both analytically and numerically, accreting supermassive black hole binaries as they inspiral due to gravitational radiation to elucidate the decoupling of b…
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…
