About 40 European institutions (8 of which are Spanish institutions) have requested that the Einstein telescope be included in the next roadmap of the European Research Infrastructure Strategic Forum (ESFRI). This third-generation gravity wave ground-based observatory can be located on the border between Belgium, Germany and the Netherlands, or on the island of Sardinia, Italy.
After the major discovery of the gravitational waves produced by the probe Ligao In the U.S. and Virgo In Europe, scientists propose to build new, more sensitive observatories of this type in order to continue to advance the new fields of astronomy they have opened up.
The so-called consortium this week Einstein Telescope (with) A proposal has been submitted to be included in the 2021 European Research Infrastructure Strategic Forum roadmap update (Esfrey), this program describes the main research infrastructure in Europe in the future.
ET is the most ambitious project of the future ground gravity wave observatory. Its conceptual design has been funded by the European Commission, and the consortium that promotes its development is composed of many European research centers and universities, and has received political support from Belgium, Poland, Spain and the Netherlands, leading Italy.
The European Gravity Observatory (EGO) in the mountain country will serve as its temporary headquarters, but the project brings together about 40 European scientific and academic institutions from France, Germany, Hungary, Norway, Switzerland and the United Kingdom.
Two sites are currently being evaluated for ET infrastructure: Euregio Meuse-Rhine, located on the border of Belgium, Germany and the Netherlands, and Sardinia, Italy. These locations are under study and will be decided in the next five years.
A new observatory for astronomy
In the past five years, today’s high-level Virgo and LIGO have made amazing scientific achievements, thus ushering in the era of gravitational wave astronomy. The adventure began with the first direct detection of these waves in September 2015 and continued in August 2017, when two observatories recorded gravity waves from two merging neutron stars.
At the same time, in the entire observable wavelength range from radio waves to gamma rays, various electromagnetic telescopes (in the earth and space) were used to observe the signal from this event.This ushered in the era Multi-messenger astronomy of gravitational waves.
Advanced Virgo and Advanced LIGO’s recent merging of two stellar black holes produced a black hole 142 times larger than the sun (so-called intermediate-mass black hole), proving the existence of these previously unknown objects in our universe.
However, to fully utilize the potential of this new discipline, a new generation of observatories is needed.The Einstein telescope will enable scientists to detect any fusion of the two Black hole Intermediate mass, therefore, helps to understand its formation and evolution. This will open up new highlights for the dark universe and clarify the role of dark energy and dark matter in the structure of the universe.
ET will discuss the physics of black holes in detail.These are extreme celestial bodies predicted by celestial theory Albert Einstein’s General Theory of Relativity, But in these places, due to the extremely strong gravitational field, the theory may fail.

The new telescope can also detect thousands of mergers or mergers. Neutron Star Every year, we improve our understanding of how substances behave under extreme density and pressure conditions that cannot be produced in any laboratory. In addition, you can explore the nuclear physics of controlling explosions. Supernova Stars.
These scientific challenges require a new observatory, such as ET, which can observe gravity waves with a sensitivity that is at least an order of magnitude better than the so-called second-generation (and previous) current detectors.
The Einstein telescope will become part of the telescope. Third GenerationIts initiator said that it will be located in a new infrastructure and will apply technology that will greatly improve current technology. The supplementary projects in the United States are expected to be as follows: Space explorer.
Spaniards attend ET Observatory
The Einstein telescope has aroused great interest in the Spanish scientific community involving gravity waves, including all the centers currently involved in the Earth (LIGO/Virgo/KAGRA) and Space (LISA) programs. Spanish researchers have made important contributions to the development of the ET physics program and the preparation of its technical design report.
In addition, driven by the development of new technologies and the potential huge returns from Spanish industry, research institutions have also provided clear support, including some special scientific and technological infrastructure (ICTS, marked with * in the list below).
A total of 23 Spanish institutions have joined the ET ESFRI program, thus providing formal political support for Spain. This is a list of the people who contributed to the proposal, with the eight people who signed the current proposal in bold.
