Joint gravitational wave-short GRB detection of Binary Neutron Star mergers with existing and future facilities

Understand

We explore the joint detection prospects of short gamma-ray bursts (sGRBs) and their gravitational wave (GW) counterparts by the current and upcoming high-energy GRB and GW facilities from binary neutron star (BNS) mergers.

• We consider two GW detector networks: (1) A four-detector network comprising LIGO Hanford, Livingston, Virgo, and Kagra, (IGWN4) and (2) a future five-detector network including the same four detectors and LIGO India (IGWN5).
• For the sGRB detection, we consider existing satellites Fermi and Swift and the proposed all-sky satellite Daksha.
• Most of the events for the joint detection will be off-axis, hence, we consider a broad range of sGRB jet models predicting the off-axis emission.
