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.

Carbon Nanotube FET Sensor

Schematic of a carbon nanotube FET sensor functionalized with an antibody to a Lyme disease biomarker protein.  The insulating substrate is shown in pink.  When antigen molecules bind to the antibody, the electrical characteristics of the FET are altered.

From the lab of Prof. Charlie Johnson.

SDSS Galaxy Survey

The UPenn Fit Catalog provides 2-d galaxy profile fits in several visible bands using SDSS data.  Additional data collected from other sources is provided to facilitate analysis. The catalog is constructed and maintained by Professor Mariangela Bernardi and her group.


Large Hadron Collider - ATLAS Higgs candidate event

An event captured by the ATLAS detector in the search for a Higgs boson decaying into two Z bosons, one of which goes into a pair of electrons and two muons (the two tracks shown in red). There is no way to tell if this particular event comes from a Higgs decay or simply from a background event such as one containing two Z bosons.


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.
