LOS ANGELES REGIONAL CHAPTER
Date: Tuesday, October 16, 2018
Speaker: Riccardo DeSalvo,
Topic: Astrophysics Learning from the Detection of Gravitational Waves
We often said that the detection of gravitational waves would open a new window on the Universe. Well, it was more surprising than expected. I will illustrate the latest events found in the data, give you a glimpse of the strange things that we see through that window, and attempt an early summary of some astrophysical implications. In the introduction I will discuss how ground vibrations could be attenuated a million-million times to bring the test masses to be quieter than the 10-18 m Gravitational Wave signal.
Dr. DeSalvo is a Senior Resident Scientist at Cal. State LA College of Natural and Social Sciences. He is a lifetime instrument maker, starting from the laser of his thesis in Pisa, then for 15 years in High Energy Physics (CERN and Cornell Lab for Nuclear Studies), finally 25 years on Gravitational Waves working on mechanical design of GW detectors (Virgo, TAMA, KAGRA and parts of LIGO), initially on seismic isolation, then on dissipation mechanisms and thermal noise in dielectric coating mirrors, the limiting factor of GW detection. Presently, he makes a living developing sensors for FB, and working on coatings and GW developments as a personal hobby, working with 3-4 students.
