Roberto Peccei

Professor and ISSNAF Founder

Prof. Alexander Kusenko

Roberto Peccei (1942-2020) was an internationally renowned particle physicist. During his distinguished career at UCLA, he has served as a department Chair (1989-1993), Dean of Physical Sciences (1993-2001), and Vice Chancellor for Research (2000-2010), overseeing a significant expansion of UCLA research efforts and the advent of major institutes on campus.

Roberto Peccei (1942-2020) was a brilliant scientist, a natural leader, a thoughtful colleague, and a special friend. During his distinguished career at UCLA, he has served as a department Chair (1989-1993), Dean of Physical Sciences (1993-2001), and Vice Chancellor for Research (2000-2010), overseeing a significant expansion of UCLA research efforts and the advent of major institutes on campus.

Roberto Peccei was born in Torino, Italy in 1942. He was a son of Aurelio Peccei, an Italian industrialist and philanthropist, who was a member of the anti-fascist movement and the resistance during the World War II, then moved to Argentina to oversee Fiat operations in Latin America, and later founded the Club of Rome with the goal of addressing the multiple crises facing humanity and the planet. Roberto completed his secondary education in Argentina and came to the United States in 1958 as a student. He obtained a B.S. from MIT in 1962, M.S. from NYU in 1964, and a Ph.D. from the MIT Center for Theoretical Physics in 1969. After a postdoctoral appointment at the University of Washington, Dr. Peccei joined the faculty at Stanford University Physics Department (1971-1978), then moved to Max Planck Institute for Physics and Astrophysics in Munich, Germany (1978-1984), and later became the Head of Theory Group at one of the largest European laboratories, DESY in Hamburg (1987-1989). Professor Peccei joined UCLA in 1989, where he conducted research in theoretical physics and served in many administrative positions, including Vice Chancellor for Research. Professor Peccei had a very significant global presence; his service extended well beyond UCLA and included service on many national and international committees on science, as well as the Executive Committee of the Club or Rome.

One of the most famous scientific contributions, and an example of Roberto Peccei’s brilliant thinking is the celebrated Peccei-Quinn symmetry, proposed in collaboration with Helen Quinn. Interactions of elementary particles, as well as the very existence of matter in the universe depend on how different the world would be under the hypothetical action of flipping all particle charges and reflecting the world in a mirror. This mathematical transformation, called “CP” is closely related to flipping the arrow of time. Some physical processes are not invariant with respect to such a transformation, which, remarkably, allows for the dominance of matter over antimatter in the universe. However, if one considers only the strong interactions, which hold the nuclei together, the CP transformation leaves them invariant even though it requires an apparent conspiracy of some seemingly unrelated parameters (the vacuum “theta angle” and a phase coming from the mass parameters of quarks). Peccei and Quinn proposed a brilliant explanation based on a new symmetry of nature. This symmetry implies, in particular, the existence of a new particle which has not yet been discovered, but which has the potential to account for cosmological dark matter, that is, for most of the matter in the universe. Peccei-Quinn symmetry emerges in other areas of physics and has been studied by many scientists in a variety of contexts.

Roberto Peccei’s seminal and groundbreaking contributions have been recognized by numerous prizes and awards. He was particularly happy to receive the J.J. Sakurai Prize for Theoretical Particle Physics awarded by the American Physical Society, of which he was a long-standing member and a Fellow, as well as Chair of Division of Particles and Fields. Roberto Peccei was also elected a Fellow of American Association for the Advancement of Science and a Fellow of Institute of Physics, UK. He was awarded the order of Commendatore in Italy, and a number of honorary professorships and lectureships. In 2016, Roberto Peccei became a member of the American Academy of Arts and Sciences.

Professor Peccei was a passionate communicator of science, who enjoyed teaching graduate and undergraduate students at UCLA. In recent years, his course on the Physics of Energy served as a source of much needed knowledge and inspiration for his students and colleagues.

The memory of Roberto Peccei will continue to inspire his colleagues, postdocs and students.

Roberto Peccei is survived by his wife Jocelyn and their children Alessandra and Aurelio. In lieu of flowers, the family encourages friends of Roberto to make donations in his honor to UCLA Physics and Astronomy, as well as Parkinson’s Disease research at UCLA.

Antonella Nota

European Space Agency Hubble Project Scientist

STScI ESA Office Head

ISSNAF Board Member, Scientific Council Chair

Moderator:

Maria Teresa Cometto

Hosts:

Consulate General of Philadelphia and IIC of New York

Antonella Nota is an astronomer with the European Space Agency, at the Space Telescope Science Institute, where she is the Head of the ESA Office. In this role, she is the senior ESA representative for the team and is responsible for Hubble outreach efforts in Europe, which includes the dissemination of the observatory’s results and communications with the public. She also directs all science policies and scientific communications that support the James Webb Space Telescope (JWST) in Europe.

Born in Venice, Italy, Antonella Nota completed her studies at the Institute of Astronomy of the University of Padova, and moved to the US in 1986.  She studies young stellar clusters, in the Milky Way and neighbors, mostly with Hubble and ground-based telescopes, because she is interested to know how stars and clusters form.

She strongly advocates combining art and science to spark the curiosity of the public, which has led to several successful partnerships with artists and curators. For example, in collaboration with German artist Tim Otto Roth, she contributed to “From the Distant Past,” which projected signals from distant galaxies observed by Hubble on the façades of buildings in Venice, Italy, New York City, and Baltimore, Maryland. She has also collaborated with curator and historian Anna Caterina Bellati to produce “Our Place In Space”, a science and art exhibit shown in Venice and Chiavenna, where 10 prominent Italian artists were asked to interpret Hubble images.

Antonella Nota has published more than 200 articles in astronomical journals and books and contributed to numerous press releases and science announcements.  She is a member of the American Astronomical Society (AAS), the International Astronomical Union (IAU) and L’Istituto Veneto di Scienze, Lettere ed Arti (IVSLA). She joined ISSNAF in 2020.

Exploring the Universe: the 30-year impact of the Hubble Space Telescope on science and society


Refurbished in orbit by astronauts five times, the Hubble Space Telescope (Hubble) is more powerful and innovative than ever. As we celebrate  its  splendid 30 years in orbit, and three decades of scientific discoveries,  Hubble continues its relentless investigation into a broad range of astrophysical objects and phenomena, ranging from our own Solar System to the most distant galaxies, to the distribution of dark matter in galaxies and clusters, from the characterization of the atmospheres of newly discovered exoplanets, to the precise studies of relative motions of nearby stars, to tracing the expansion of the Universe. Working in synergy with other observatories, from the ground and space, Hubble continues to be a prominent presence on the astronomical discovery scene and its observing time is in high community demand.

Not only has Hubble transformed our knowledge of the Universe but it has greatly impacted culture, society and art for three decades. Hubble has broadened the reach of astronomical research, a science that for years was perceived to be reserved to a privileged few, and made it a resource available to all. It has brought the Universe to our houses, and is continuing to inspire generations of students. Hubble has become a presence that belongs to all, the “people’s telescope”. Its beautiful images connect directly with our souls, sparking the big questions that humanity has been pondering in the centuries: where do we come from? Are we alone in are we alone in the Universe? What is our place in space?
