Magnetars are some of the most extreme objects in the known universe. Though small in size, they possess the strongest magnetic fields in the universe and are the densest objects known. In this talk, we’ll go over the incredible behaviour seen in these rare objects — from tiny explosions to outshining the rest of the X-ray sky combined.


About the Speaker

Robert Archibald is currently a Postdoctoral Fellow in the department of Astronomy & Astrophysics at the University of Toronto. He completed his undergraduate degree in physics at Dalhousie University in Halifax, before moving on to do his Master’s degree and doctorate at McGill University in Montreal. He is generally interested in using pulsars to probe the most extreme environments in the universe.


The U of T Astronomy Public Tour, or AstroTour, is a monthly event operated by the graduate students of the U of T Astronomy Department. The Tour features a public lecture by a member of the Department on topics ranging from their research to great moments in astronomical history. Following the lecture, tour-goers can peer at the night sky through the Department’s balcony and dome telescopes, or watch a planetarium show run live by astronomer. Admission to the tour is free. Seating for the lecture is on a first-come, first-served basis (doors open ten minutes before the start of the lecture), and the telescope observing is walk-in. The planetarium shows require registration, found at the top of this page.

The AstroTours are generously financed by the Department of Astronomy and Astrophysics and the Dunlap Institute for Astronomy and Astrophysics.
