About:

Precision timing of an array of millisecond radio pulsars spread across the sky can be used to look for low-frequency gravitational waves.  In June 2023, the North American Nanohertz Observatory for Gravitational Waves (NANOGrav), along with other pulsar timing array collaborations, released evidence for such gravitational waves, likely in the form of a stochastic background due to supermassive black hole binaries in the universe.  I will review the NANOGrav observational and detection methods, and discuss the implications of our find.

 

Bio:

Ingrid Stairs graduated from McGill University in Honours Physics and subsequently got her PhD in Physics from Princeton University. She was an NSERC postdoctoral fellow at Jodrell Bank Observatory at the University of Manchester in the UK, then a Jansky Fellow of the National Radio Astronomy Observatory in Green Bank, West Virginia.

She has been on the faculty at UBC since 2002 and devotes her research time to the study of radio pulsars and Fast Radio Bursts using some of the world's largest radio telescopes, including the CHIME telescope near Penticton, BC.  She has won awards including the Canadian Astronomical Society Peter G. Martin Award for Mid-Career Achievement and the
Royal Society of Canada Rutherford Memorial Medal in Physics.  She is a Fellow of the CIFAR Gravity and Extreme Universe Program and of the American Physical Society.
