At Last, Astronomy with Particles

Presented by Emeritus Prof Roger Clay, University of Adelaide

Prior to the 20th Century, astronomy was only possible through the use of visible light. In the past century there has been a revolution in the use of “light” at other wavelengths – radio, x-rays, gamma-rays. The study of other “particles”, cosmic rays, as “messengers” began 50 years ago but progress was difficult and slow. However, in the past 5 years new particle “messengers” have become accessible in the form of gravitational waves and neutrinos. In the past year, there have also been breakthroughs in the study of cosmic rays. These new windows on the Universe are not yet well understood but astronomy is now very different to what it was a decade ago. The puzzles being currently addressed will be discussed in this talk.

Bio: Roger Clay was born in South Yorkshire in England and went to university in London, at Imperial College. He received his Honours degree there in 1967 and went on to do a PhD in the Cosmic Ray Group, supervised by Harold Allan, a physicist of great intellect. His PhD on radio emission from cosmic ray showers was completed in 1971 and included two years working on the Haverah Park airshower array, based at the University of Leeds. Roger has worked at the University of Adelaide since 1971 and has carried out research in astrophysics for over 45 years. Such work has taken the High Energy Astrophysics group at the University of Adelaide into a number of major international scientific arenas. His research interests include cosmic rays and cosmic ray detection, cosmic ray sources, the knee, anisotropy, building detectors, Cerenkov stuff, archaeoastronomy and understanding how smart ancient people were, VLBI, cosmic ray acceleration - and its sites, cloud detection, scattering, tachyons, understanding how students perform when examined.
