Antimatter under a sharper lens: Purdue physicist helps ALPHA Collaboration test one of nature's biggest questions
Why is the universe filled with matter when our best theories say matter and antimatter should behave almost exactly the same way? A new Nature study from CERN's ALPHA Collaboration is putting that question under a sharper lens, measuring a key property of antihydrogen with 100 times greater precision than previous measurements. Purdue University physicist Francis Robicheaux contributed simulations that helped researchers interpret what was happening to antihydrogen atoms inside the experiment.
On a flight into space, Purdue researchers will test forces that could determine how we find our way, build and survive in space
In 2027, Purdue researchers will follow that bead of liquid aboard a Virgin Galactic spacecraft and into microgravity, chasing answers that could determine how spacecraft navigate, how manufacturing for the supply chain can be accomplished in space, and how humans can survive and function there.
The Road to the Stars: Five out-of-this-world facts about campus astronomical observatories

AAS Journal Author Series: Miranda Pikus and Paul Duffell
YouTube — Miranda Pikus and Paul Duffell (Purdue University) chat about their article on how thermal cooling creates structural changes in supernova remnants as they evolve, finding that when the cooling timescale is shorter that ~1/400 of the Sedov time, the ejecta are shaped into a filamentary structure similar to Pa 30. The filament structures are created by the formation of Rayleigh–Taylor instability fingers where the cooling has prevented the Kelvin–Helmholtz instability from overturning and mixing out the tips.
Braiding Anyons in a Semiconductor Sandwich
YouTube — Every particle in the standard model is either a fermion or a boson. So how did physicists create a third kind of particle, and how did they know they had succeeded? Be sure to watch Purdue Physics and Astronomy Professor Erica Carlson's new video on The Quantum Age on YouTube.
