The XII ET Symposium, which took place in Budapest from June 7 to 8, marked the real start of the Einstein Telescope (ET) collaboration.
The large community of some 1,200 physicists is now in working order to give life to this vast project for a third-generation European gravitational wave detector. The Gravitational Waves team of the A2C Pole of IJCLab, led by Nicolas Leroy, is fully involved in this new collaboration.
This 10 km long instrument will be ten times more sensitive than its current predecessors Virgo and LIGO. The detection of the first mergers of black holes and neutron stars by Virgo and Ligo has also accelerated the Einstein Telescope project, imagined about fifteen years ago.
