Welcome to the Waterloo Centre for Astrophysics

    ...where the Universe is our laboratory.

 The Waterloo Centre for Astrophysics (WCA) looks to the cosmos to solve the greatest mysteries of the universe. Here, world-class researchers and students come together in an atmosphere of curiosity, creativity and collaboration; exploring our cosmic origin to truly understand the physical processes at work in the Universe. From black holes to cosmology, we aim to understand what lies beyond the Earth. The possibilities for new discovery are limitless.


The Gustav Bakos Observatory houses a twelve-inch telescope, which is located on the roof of the Physics building. The observatory, in operation since 1967, has been used for research on and teaching about visual binary stars.

    Astrophysicists release largest 3D map of the universe ever created

    Astrophysicists have filled in 11 billion years in our picture of the universe with the release of a comprehensive analysis of the largest three-dimensional cosmic map ever created. 

    “This is one of the most substantial advances in cosmology in the last decade,” said University of Waterloo professor Will Percival, a lead researcher on the work.

    A group of astronomers led by Dr Sesh Nadathur at the University of Portsmouth, and including WCA Director Will Percival, have spent the last 3 years studying large structures in the distribution of galaxies in the Universe to provide the most precise tests of dark energy and cosmic expansion yet.

    My research area is cosmology and gravitational lensing. The questions I study are: How did small fluctuations in the early universe grow  to form the large-scale structure observed today? What is the nature of dark matter and dark energy? And how did these mysterious components of our universe shape the formation of galaxies and clusters?  

    Gravitational lensing is the shearing and magnification of light we receive from distant galaxies. I use ‘weak’ lensing, the small distortions in the shapes of millions of galaxies, to map the large-scale distribution of dark matter and address cosmological questions.  My other interests span a variety of topics in theory and data analysis, largely enabled by massive cosmological surveys.
