Large Synoptic Survey Telescope at Night

A simulated night sky provides a background for the LSST facilities building on Cerro Pachón. The LSST will carry out a deep, 10 year imaging survey in six broad optical bands over the main survey area of 18,000 square degrees. Penn physicists play important roles in the leadership and anticipated dark energy science that will come from LSST.

 

Proteins on Carbon Nanotubes

The image shows an example of peptides that assemble into a tubular structure surrouding single-walled carbon nanotubes.  The geometrically defined, virus-like coating created by these peptides converts the smooth surfaces of carbon nanotubes into highly textured assemblies with long-scale order, capable of directing the assembly of gold nanoparticles into helical arrays along the nanotube axis.

 

The Best View in Philadelphia

The University of Pennsylvania recently finished their newest addition to the campus, Penn Park, which adds a brilliant contrast to the Philadelphia skyline and gives multiple sports teams a new place to practice and engage in athletics.

Majorana Fermions, Topological Insulators and Superconductors

Magnetic diffraction pattern for a Josephson junction with a topological insulator weak link. Building on a theoretical description published in 2008 by Prof. Charles Kane and Liang Fu at Penn, Stanford researchers believe the unusual behavior is explained in terms of Majorana fermions.
