Dark Energy Survey

The Dark Energy Survey (DES) uses a 570-Megapixel digital camera at the Blanco 4-meter telescope at Cerro Tololo Inter-American Observatory in the Chilean Andes to probe the origin of the accelerating universe. Penn scientists are among the 120 scientists from 23 institutions in the US, UK, Brazil, and Germany working on the project slated for first light in Fall 2012.

 

MUSTANG - a Penn Radio Telescope Array

Penn,the National Institute of Standards and Technology, NASA's Goddard Space Flight Center, and the National Radio Astronomy Observatory, have built a 3 millimeter array of 8x8 TES detectors for the Green Bank Telescope (GBT).

Topological Insulators

This image shows the valence and conduction bands in the phase transition from topological insulator to conventional insulator with increasing tensile strain.

 

Graphene

Penn physicists study graphenes, atomically thin sheets of carbon atoms in a honeycomb lattice. Graphene is the prototype Dirac material hosting a solid state realization of an ultra-relativistic electron gas and accessing new phenomena that are controlled by electric and magnetic fields and by the atomic registry when graphenes are stacked.
