Description
The detection of a GW has become now an ordinary event after the first
detection that hit the news just 2 years ago. Numerous upgrades have been
developed and installed one after the other all along the many years
(twenty) since the large interferometers have been built. This presentation
considers one of the key elements of the interferometers that made possible
to listen the Universe: the mirrors. How they are made, what’s the meaning
of high-precision and of low-noise as referred to mirrors and the
challenges that scientists had been confronted to and those that need to be
faced in the future will be the main subjects of this presentation.
