Dear colleagues


The long journey of the Einstein Telescope (ET) has reached a crucial point: we are ready to launch the foundation of the ET Collaboration.
The ET Steering Committee has established an initial set of definitions and rules (ET Bylaws) that provide the framework for the ET Collaboration in its initial phase.

You can find the “ET bylaws” document at the link:

https://apps.et-gw.eu/tds/ql/?c=16220

The building blocks of the ET collaboration are the Research Units (RU) and the ET Steering Committee is now launching the call for proposals of new RUs in ET. The procedure to submit a proposal for a new RU in ET starts at this link, where an online form and an offline Excel file have to be filled in for each new RU proposal.

The collection of RU proposals will be permanently open, but only the proposal received within the 31st of May 2022 will be “used” to form the first Collaboration Board, which will meet during the next ET Symposium.

 

The XII ET Symposium will be in Budapest (Hungary) the 7-8 of June, 2022. The symposium is organised in a hybrid configuration, both in person and via Zoom.

As the number of participants is limited, we invite you to register as soon as possible on the Indico page: https://indico.ego-gw.it/event/411/

 

The Symposium will be a crucial step in the formation of the ET collaboration, following the procedure described above, and your participation is warmly recommended.


During the ET Symposium, the current status of the Collaboration, the exciting progress of the ET project and the scientific and technical progress in ET design will be presented; the focus will in any case be on the kick-off of the Collaboration.
We very much hope to see you in Budapest at the XII. ET Symposium.

The upcoming ET Symposium will take place in Maastricht from May 6th at noon until May 10th early afternoon. This symposium gives the chance to unite with colleagues deeply engaged in the Einstein Telescope project and those who share a profound interest in ET. Together, we'll delve into recent advancements and exchange insights while forging lasting connections.

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 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.

All the details are available in the Indico page of the event:

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.
