Talk	Oral abstract	Title	Multi-messenger insights into merger physics: GW170817 and beyond
Coauthors
Abstract	With the first gravitational wave detection on September 2015 and the forthcoming new developments of gravitational interferometers, neutrino detectors, as well as ground- and space-based telescopes, a golden era of multi-messenger astronomy is approaching. Multi-messenger observations enable us to obtain a more complete phenomenological picture of several astrophysical phenomena. The most beautiful example so far is represented by the binary neutron star merger detected on August 17th, 2017 by the gravitational wave detector network (formed by Advanced LIGO and Advanced Virgo) and by several telescopes covering the whole electromagnetic spectrum. Multi-messenger observations of this source have enabled us to make huge steps forward in our knowledge of merging neutron star binary systems and their connection with short gamma-ray bursts and with the Universe chemical enrichment of heavy elements. Many other open questions will be tackled in the next years given the realistic possibility to obtain multi-messenger observations for a large number of such systems with the present and future instrumentations. In this talk I will summarize some of the main results obtained for GW170817 and the future perspectives for multi-messenger astronomy.

Talk	Oral abstract	Title	The Multi-messenger era of GRB observations and the role of THESEUS
Coauthors
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.
