Seminario

Il giorno 21 marzo alle ore 15 presso la sala 412,  Marco Bazzan (Istituto Nazionale di Fisica Nucleare & Padova University) terra' un seminario dal titolo

Observing the Universe by looking at matter at the scale of 10^-20 m

Abstract

Nine years after the first gravitational wave detection, the scientific community is gearing up to develop the next generation of GW detectors that will be able to probe the visible Universe and beyond, down to the Dark Age, when stars had not yet been born. To achieve this goal requires a huge effort to improve the performance of all detector subsystems. The seminar will focus on reducing thermal noise that limits the detector in the frequency band where it is most sensitive. Reducing the dissipation processes within the materials used in the mirrors (and their suspensions) offers the possibility of acquiring unique information about black holes and neutron stars on the other side of the Universe. The status of materials research for the Virgo and LIGO detectors and the prospects for future detectors, such as the Einstein Telescope and the Cosmic Explorer, will be explained. Finally the novel CoMET (Coating Materials for Einstein Telescope) laboratory that is being built under the umbrella of the PNRR - ETIC project will be presented.
