Appointment of Professor Justin Khoury as co-Director of the Center for Particle Cosmology

The Center for Particle Cosmology would like to announce an important leadership change. Professor Mark Trodden, who has co-directed the center since its founding in 2009, was recently announced as the new Dean of the School of Arts and Sciences, and has decided to step down as co-Director, effective May 1, 2025. Professor Trodden will, however, continue as a key member and contributor to the Center.

Mark Trodden named dean of Penn’s School of Arts & Sciences

Mark Trodden has been named dean of the School of Arts & Sciences and the Thomas S. Gates Jr. Professor at the University of Pennsylvania, effective June 1. The announcement was made today by Penn President J. Larry Jameson and Provost John L. Jackson Jr.

In the Arnold Mathijssen lab, researchers used a gooseneck kettle, coffee grinder, and a pour-over setup alongside precise measurements and high-speed analysis to study the fluid dynamics and mechanics of coffee brewing to uncover ways to maximize flavor with fewer grounds. The findings could help researchers understand fluid dynamics.

For a better cup of coffee, look to physics

Researchers led by Arnold Mathijssen of the School of Arts & Sciences have applied fluid mechanics to brew the best cup of pour-over coffee using the fewest granules. The findings have potential application to other systems such as surface erosion, filtration, and even wastewater management.

New high-definition pictures of the early universe

New research by the Atacama Cosmology Telescope (ACT) collaboration has produced the clearest images yet of the universe’s infancy—the earliest cosmic time currently accessible to humans. Measuring light that travelled for more than 13 billion years to reach a telescope high in the Chilean Andes, the telescope’s images reveal the universe when it was about 380,000 years old—the equivalent of hours-old baby pictures of a now middle-aged cosmos.
