Experimental Gravitation

Fulvio Ricci is Full Professor of Experimental Physics at the University of Rome, La Sapienza. He started his scientific career working in the Gravitational Wave (GW) group of Professor E. Amaldi at Rome University. For more than fifteen years, he was at CERN installing and operating the 2300 kg GW detector EXPLORER, which achieved the sensitivity goal of an h~10-19 GW burst 1 ms in duration. In 1995, he became Data Analysis Coordinator for the VIRGO project, a collaborative effort between the two funding agencies INFN-Italy and CNRS-France, for the construction of a 3-km laser interferometer for detecting GWs. From 2007 to 2014, he served as INFN Italian Coordinator of VIRGO, subsequently becoming international collaboration’s Official Spokesperson from 2014 to 2017. Nowadays, he is involved in the Einstein Telescope project devoted to the construction of the new generation of GW detectors on the Earth.Massimo Bassan is Associate Professor of Physics in the Department of Physics at the University of Rome, Tor Vergata. He graduated from Sapienza with E. Amaldi and G. Pizzella, developing the first Italian prototype interferometer for gravitational waves. He received his Ph.D. from Stanford University, working with W.M. Fairbank and then spent many years developing and operating cryogenic resonant antennas. He is presently involved with LISA, the space-based gravitational wave detector, as well as with a laboratory experiment `` Liquid Activated Gravity"  using a double torsion pendulum.
