Title: High-precision mirrors for low-noise interferometry: the hidden 
quest behind the detection of the Gravitational Waves
Speaker:  Prof. Gianpietro Cagnoli

Abstract:
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.
