The ET Letter of Intent submission procedure doesn't give back a feedback. On output file with the result of the signatures is created every few days at the address:


In order to progress with the ET concepts, to prepare the submission of the ESFRI proposal, to strengthen the ET community a series of teleconferences is organised with monthly frequency. The agenda and the documentation can be fond in this wiki page:


The 9th ET Symposium is hosted by European gravitational Observatory, Cascina (Italy). The focus of the meeting is the creation of the ET collaboration, the definition of the strategy for the submission of the ET proposal to the 2020 update of the ESFRI roadmap. We will discuss the future of the GW astronomy and astrophysics. 

Registration opens on the 15th February 2018. Here it is the link to the event: 9th ET Symposium.

The Italian government, through the Ministry of Education, University and Research (MIUR), INFN, Sassari University and Regione Sardegna support the candidature of the site close to Sos Enatto (Sardinia) for the Einstein Telescope infrastructure. More details (in Italian) here.

Tuesday, 9th of January, 2018, more than 150 physicists, astrophysicists, policy makers, representative of the funding agencies and of the European Institutions meet in Brussels in the occasion of the APPEC roadmap. APPEC is the consortium of funding agencies that in Europe support the research in astroparticle and in particular the research in gravitational waves through terrestrial detectors. The APPEC roadmap represents the vision of the national funding agencies and of their scientists about the future research infrastructures and main research subjects in astroparticle in the next decade. Gravitational Waves play a central role in that roadmap, with the evolution of the current detectors, Advanced Virgo and Advanced LIGO, and the future 3rd generation GW observatory, the Einstein Telescope (ET), the key European research infrastructure that will lead the GW research in the 2030 decade. The whole meeting has been dominated by few words: “gravitational waves” and “multi-messenger astronomy and astrophysics” (MMA). In fact, the first detection of the coalescence of two binary neutron stars (GW170817), achieved by Advanced Virgo and Advanced LIGO the 17th of August 2017, opened the new MMA era. Hence, the plan for future research infrastructures in astroparticle needs to be though within this new framework, realising something to be named with a new title: the MMA roadmap.
