Today, Dr. Art McDonald joined students and leaders from Queen's University and NSERC to reflect on the legacy of the SNO experiment on the 10th anniversary of receiving the Nobel Prize in Physics with Dr. Takaaki Kajita for the discovery of neutrino oscillation. Read more at bit.ly/3W8GHHt

... and part II of our gravitational wave bias work is out! Huge thanks to Dorsa for leading the work~

Who were the first to discover the cosmic glow of the Big Bang, known as the CMB (or cosmic microwave background)?

Hint: It’s not who you think it is.

Attention physicists! The abstract deadline for the 2025 Women+ in Physics Canada Conference has been extended to May 2! Share your research with a national audience committed to advancing gender equity in physics. WIPC+ is open to all physicists - please share and encourage others to submit!

Dimming Starlight with Dark Compact Objects Compact objects formed from dark matter could be detected by examining the dimming of background light when the dark objects pass across the line of sight with Earth.

A bit late, but happy that our work was published in PRL last week! With Melissa Diamond and @joebramante.bsky.social, we explored a new way to search for diffuse clumps of dark matter if dark matter and photons interact. Check it out!

The C. N. Yang Institute for Theoretical Physics at Stony Brook! Had a great time visiting to give a seminar. Thanks for the invite and the fun discussions~!

If you’ve been hoping origin of cosmos could be less dramatic than current affairs, here’s a rigorous work by Amir Dehghani, Jerome Quintin & me showing Cuscuton bounce has no strong coupling problems & is within observational non-Gaussianity bounds.

Thanks to all my collaborators, especially Amir for leading the work! Always a great learning experience working with @ghazalgesh.bsky.social 😁. Be on the lookout for part 2 led by Dorsa 👀
