The legacy of Guido Pizzella in gravitational wave research
Guido Pizzella, a visionary in the study of gravitational waves, passed away, leaving an indelible mark on science. Alongside Edoardo Amaldi, he initiated experimental research in Italy during the 1970s, designing the Explorer and Nautilus resonant-bar detectors.
Explorer, operational at CERN from 1990 to 2012, and Nautilus, active at the INFN Frascati Labs until 2016, were innovative in their design. Although unable to directly detect gravitational waves, their significance laid the groundwork for revolutionary advancements in the field.
From resonant bars to interferometry: paving the way for Virgo
Pizzella’s work inspired the development of interferometric detectors such as Virgo, in collaboration with the U.S. LIGO detectors. This groundbreaking technology achieved the first direct detection of gravitational waves in 2015, ushering in the era of gravitational astronomy. In 2016, Pizzella was awarded the Amaldi Medal for his trailblazing contributions.
Scientist, mentor, and innovator
Pizzella’s career extended beyond gravitational waves. Early in his journey, he collaborated with James Van Allen on Earth’s magnetosphere studies. Upon returning to Italy, he contributed to the first ESRO satellite and delved into space plasma physics. Even after retirement, he pursued research on cosmic rays, leaving an enduring legacy.
Renowned as a beloved professor at La Sapienza and Tor Vergata universities, Pizzella shaped countless students and colleagues, fostering innovation and curiosity.
A legacy that inspires future generations
The passing of Guido Pizzella marks a profound loss for the scientific community. Yet his groundbreaking work continues to inspire and guide new discoveries, ensuring his impact will resonate for generations to come.
