Abstract:

The standard model of cosmology, also known as the big-bang model, is successful in accounting for the ordinary matter that makes up planets, dust, stars and everything else that is made of protons and neutrons (baryonic matter). However, there is extensive astrophysical evidence that most of the matter in the Universe is dark and non-baryonic. This dark matter is detected only by its gravitational pull as it does not emit nor absorb electromagnetic radiation. It is widely accepted that dark matter is made of elementary particles even though such a particle has yet to be discovered.

Dark matter is expected to exist in scales ranging from galactic to cosmological and therefore must exist in our own galaxy, where an ongoing experimental effort searches for it. In this talk, we will present an overview of the field and in particular discuss in detail the status of the PICASSO dark matter search experiment.

Dr. Wichoski is a short-listed applicant for the Tier II CRC in Particle Astrophysics.

Refreshments will be available after the talk.
