Catching Ghosts: Using Neutrinos to Unveil the Universe

On a clear night, away from the bright lights of Vancouver, you can see the incredible expanse of the universe before you. To study these far-away celestial bodies, scientists use a “radiation toolkit” to observe our universe and understand how the galaxies we see today came to be. Some types of radiation, such as infrared radiation, can sense stars in their infancy, not yet hot enough to shine visible light. Others, like x-rays and gamma rays, can reveal matter being sucked into a black hole.

When it comes to studying the nuclear processes in the heart of stars, scientists must turn to neutrinos: subatomic particles that are currently flying unbeknownst through your body by the billions, right this second. These elusive little particles are an excellent probe into the core of the sun and distant supernovae, but they are notoriously difficult to detect. Difficult, but not impossible.

On Tuesday, October 23, join Dr. Stanley Yen, TRIUMF Research Scientist, for his talk, Detecting the Ghost Particles of the Universe.
