The Multi-messenger era of GRB observations and the role of THESEUS |
|
Abstract |
The recent discovery of gravitational waves (GW) from the short GRB 170817 has demonstrated the huge informative power of multi-messenger observations for these astrophysical events. Long GRBs are also expected to emit high-frequency GWs, although the estimated GW energy output from core-collapsing massive stars is still affected by large uncertainties. During the next decade, multi-messenger astronomy will reach a mature stage, where the consolidated network of the second generation GW detectors will be further powered by the contribution from third generation interferometers such as Einstein Telescope and/or Cosmic Explorer. In addition, sensitive neutrino detectors (e.g. KM3Net, IceCube-Gen2) are expected to become operational. THESEUS is a space mission concept recently accepted by ESA for phase A study that, if selected, will ensure GRBs observations on 2030 and beyond. In this talk, I will review the THESEUS capabilities in detecting GRBs in the golden era of multi-messenger astronomy. |
