Description
The event GW170817, which was for the first time associated to the e.m. event GRB 170817A, proved that at least a portion of Gamma-Ray Bursts (GRBs) are counterparts of Gravitational Wave (GW) events involving a neutron star. Despite the incredible amount of follow up detections of GW170817, though, no other event of this kind has been later observed. Of great importance is to set up a joint analysis between GWs and very-high energy (VHE) gamma-ray observatories, such as the CTAO, since in these extreme events we may obtain fundamental hints for the investigation of the acceleration processes and the environment near compact objects. These kind of observatories, moreover, have a small field of view and need to be pointed to the source, and the information on the sky localization provided by GW detectors is crucial for a low latency detection.
In our work we have considered a binary neutron star (BNS) population and associated to each event a GW signal and a GRB. We then built two different analysis pipelines, considering a joint detection between CTAO and the two cases of current and third generation (such as the Einstein Telescope) GW observatories. Even in this preliminar work we still get interesting results on the joint detection prospects, which serves as a basis for our ongoing work.
