The XIII symposium of the Einstein Telescope (ET) will be held in Cagliari, at the THotel from May 8th to May 12th 2023. 

The Symposium is organized in parallel sessions, hosting workshops managed by the ET specific boards (EIB, ISB, OSB and SPB), and a plenary sessions to have a global view of all the activities on going.  

Along the week several lectures on the physics of ET will be organized with the support of the OSB for PhD students and young researchers.

Krzysztof (Chris) Belczynski  pioneered the study of massive black hole formation from the collapse of metal-poor progenitors, several years before the advanced detectors' era. He demonstrated that binary population synthesis is the necessary starting point to understand the (astro)physics of binary compact objects, unraveling the importance of stellar winds, mass transfer, and common envelope. Thanks to his work, we  understand why LIGO and Virgo have observed many more binary black holes than neutron star mergers. For many years to come, his models will be a cornerstone for the science case of the Einstein telescope, as well as for the other implications of massive binary star evolution across cosmic time. His volcanic, unconventional, and provocative personality will be sorely missed.

 

 

The 2nd Einstein Telescope Annual Meeting (Nov, 14, 2023 - Nov, 16, 2023)  will be the opportunity to discuss key points of the ET collaboration and of the ET design.

The meeting is hosted by the “Gravitational waves” group of the Astroparticles, Astrophysics and Cosmology (A2C) department of the Irène Joliot-Curie Laboratoire des deux infinis (IJCLab). It will take place in the IJCLab Lehmann auditorium (building 200) in the campus of the Paris-Saclay University. Open to all ET collaboration members, it will start on Tuesday morning November 14th and end on Thursday November 16th at lunch time. In-person and remote registrations are possible.

The second Site Preparation Board (SPB) workshop will take place from23-26 January 2023, Maastricht (NL). This will be the occasion to discuss and get updates on the various activities taking place at the sites aspiring to possibly host the future Einstein Telescope (Sardegna in Italy, EMR partially in Belgium, Germany & The Netherlands and possibly Lausitz in Germany). In particular (hydro)geology aspects, noise environment, legal/permitting affairs, bidbook organization, schedules, excavation costs, local funding and future plans, etc. will be discussed. Apart from plenary presentations, lots of time will be reserved for discussions. 

The venue of the workshop is Thiessen Wineries, Maastricht, Grote Gracht 18, 6211SW, Maastricht, The Netherlands. See: https://thiessen.nl/. A maximum of 50 participants can be hosted in person. A video (Zoom) link will be provided to allow remote attendance.

The ET Monthly meetings are regular meetings, in general the first Tuesday of each month, where the status of the activities is described and where to discuss the hottest topics in ET. Because of the proximity of the ET annual meeting, the 8th of November 2022 Monthly meeting is cancelled.

The XII symposium of the Einstein Telescope (ET) took place in Budapest, at the Hungarian Academy of Sciences, on the 7th - 8th of June. The ET scientific community met in Budapest for a crucial step in the long Einstein Telescope journey: the formal establishment of the ET Collaboration.

More than 400 scientists, out of more than 1200 members of the Collaboration, parti cipated in the meeting in person or remotely. The ET members discussed the status of the experiment, the technical challenges, the scientific case, and the scientific and technical progresses made by each of the ET boards. The ET Project Directorate presented the perspective from the funding agencies. Finally, the approved INFRA-DEV Horizon EU project, for supporting the preparation phase of the experiment, and the INFRA-TECH Horizon EU proposal, recently submitted to Brussels for supporting technological R&D activities, were  introduced to the whole Collaboration.  

During the meeting in Budapest,  the ET Collaboration Board (CB) was constituted, temporary chaired by Dr. H. Lueck (AEI), composed of the representatives from each of the 79 research units from 13   countries. During the first CB meeting, the ET Collaboration discussed  the recently created ET bylaws that will govern the future of the experiment and initiated procedures to set up the  required Collaboration committees.     In addition, interim ET Spokesperson (Michele Punturo, INFN) and Deputy Spokesperson (Harald Lueck) figures were identified.  


With the birth of the ET Collaboration, this  symposium marks a milestone on the long journey of the Einstein Telescope endeavour.
