Perspectives for multi-messenger astronomy with the next generation of gravitational-wave detectors and high-energy satellites

Understand

The Einstein Telescope (ET) is going to bring a revolution for the future of multi-messenger astrophysics.

• In order to detect the counterparts of binary neutron star (BNS) mergers at high redshift, the high-energy observations will play a crucial role.
• Here, we explore the perspectives of ET, as single observatory and in a network of gravitational-wave (GW) detectors, operating in synergy with future $\gamma$-ray and X-ray satellites.
• We predict the high-energy emission of BNS mergers and its detectability in a theoretical framework which is able to reproduce the properties of the current sample of observed short GRBs (SGRB).
