Making ‘light’ work of computing  

Penn physicists led by Bo Zhen have created hybrid light-matter particles that interact strongly enough to compute, pointing toward ultrafast, low-energy optical AI hardware.

What happens when an iceberg melts?

With ice balls, lasers, and cameras, School of Arts & Sciences’ Hugo Ulloa recreated a melting iceberg in his lab. This project revealed that icebergs don’t sit passively on the water’s surface but actually release dense, cold water and jet across the surface, churning and mixing everything in their paths.

Gravity follows Newton and Einstein’s rules, even at cosmic scales
An artist's depiction of two galaxies, side-by-side, swriling at different velocites.

The cosmic microwave background, the faint afterglow of the Big Bang that fills all of space, passes through massive galaxy clusters whose motion slightly alters the light, allowing scientists to measure how fast the clusters are moving toward one another and test how strongly gravity pulls across the largest distances in the universe.

Gravity follows Newton and Einstein’s rules, even at cosmic scales

By tracking galaxy clusters hundreds of millions of lightyears apart, Penn physicist Patricio Gallardo and collaborators find that the laws of gravity written by Newton and Einstein still hold, leaving little doubt that invisible dark matter exists.

Mapping the expanding cosmos: Dark Energy Survey unveils clearest picture yet
Terrestrial telescope in Chile under a starlit sky.

The Dark Energy Survey used a 570-megapixel camera mounted on the 4-metre Victor M. Blanco Telescope in Chile to image 5,000 square degrees of southern sky. The survey discovered more than 1,000 supernovae and mapped millions of galaxies to help astronomers better understand the accelerating expansion of our universe.

Mapping the expanding cosmos: Dark Energy Survey unveils clearest picture yet

The Dark Energy Survey collaborative, including Penn researchers, recently released an analysis that gives the clearest picture yet of how dark energy is driving the universe’s expansion and how matter—including galaxies and groups of galaxies—has been organized over cosmic time.
