| Resumen |
The connection between short Gamma-Ray Bursts (sGRBs) and Gravitational Waves (GWs) has long been a subject of study, motivating the search for counterparts by gamma-ray instruments. Both phenomena are thought to be produced by the same astrophysical event. However, only one event to date has been identified as a simultaneous occurrence of both, a sGRB (GRB 170817A) and a GW (GW170817). GRB 170817A was classified as an unusual burst due to its low-luminosity and prolonged non-thermal emission (afterglow) observed across radio, optical, and X-ray bands, which reached their maximum hundreds of days after the trigger time. Although TeV emissions were not immediately observed for this burst, if they exist, they are most likely generated through synchrotron-self-Compton of the delayed radio emission from each burst. We have identified 8 sGRBs within the Fermi Gamma-ray Burst Monitor catalogue that appear to share some characteristics with GRB 170817A during the time interval spanning from December 5th, 2014 until December 5th, 2022. In this work, we discuss the methodology utilized to identify sGRBs that are alike GRB 170817A and discuss the implications of our results. © Copyright owned by the author(s) under the terms of the Creative Commons. |
