Particle Astrophysics Particle Astrophysics

The Queen's Particle Astrophysics group is a world leader in the field, and pursues questions that are found at the intersection of astrophysics and particle physics. Questions such as "What is the nature of dark matter and dark energy?", "How have the properties of particles, like the neutrino, shaped the evolution of the universe?", "What are cosmic rays and what accelerates them?", "Are protons stable?" and "Are there additional space-time dimensions?".

Queen's Particle Astrophysics Group

The group has seven faculty members, all experimentalists involved in several large projects based at SNOLAB. SNOLAB is the world's deepest underground laboratory for physics, built as an extension of the Sudbury Neutrino Observatory, a solar neutrino detector. The SNO experiment has been a major success in physics and astrophysics. SNO discovered that solar neutrinos change flavour or "oscillate" as they propagate from their place of origin in the Sun to the Earth and SNO confirmed our understanding of the energy generation mechanism inside stars. Knowing that neutrinos oscillate implies that they have a finite mass, with implications for cosmology.

Exciting new experiments are planned that aim to detect dark matter particles, probe the fundamental properties of neutrinos, and detect geoneutrinos, the antineutrinos emitted by radioactivity in the Earth.
