The Precision Array for Probing the Epoch of Reionization is a radio interferometer designed to detect 21 cm Hydrogen (HI) fluctuations occuring when the first galaxies ionized intergalactic gas at around 500 million years after the Big Bang. The Penn PAPER team is led by Professor James Aguirre.
Vector Bundles on Calabi-Yau Manifolds
Supersymmetric vacua of the heterotic string and M-theory are explored through the study of complex algebraic geometry. The figure is from a recent paper by Prof. Burt Ovrut and collaborators on the Kahler cone substructure associated with the SU(2) bundle for different Kahler moduli.
David Rittenhouse Laboratory - Walnut Street view
DRL is the academic home of the Mathematics and Physics and Astronomy departments at Penn. It is named for David Rittenhouse, a noted American astronomer born near Germantown, Philadelphia. Rittenhouse was one of the first to build a telescope in the United States and was Professor of Astronomy at Penn starting in 1779.
A synthetic peptide candidate that can be used for single molecule electronic measurements. Single molecules can act as a functioning part of a field effect transistor device as studied in Professor Charlie Johnson's lab.
Improving crop yields in marginal, sandy soils is critical to feeding
the world’s growing population. But when water is added to dry
soils—either from rainfall or irrigation sources—it tends to flow in
channels, as opposed to spreading out evenly, an effect that prevents
water from reaching all plant roots.
The David and Lucile Packard Foundation announced Wednesday that Alison
Sweeney, an assistant professor of physics and astronomy at the
University of Pennsylvania, will receive a 2014 Packard Fellowship for
Science and Engineering.
A Message from Penn President Amy Gutman on Packard Fellowship Win
Evolution in extreme environments has produced life forms with amazing abilities and traits. Beneath the waves, many creatures sport iridescent structures that rival what materials scientists can make in the laboratory.
