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.


The SNO+ Experiment

SNO-plus is a multi-purpose neutrino experiment, located 2km underground in an active nickel mine in Sudbury, Ontario. It is a large liquid scintillator experiment, currently under construction, inheriting most of the detector hardware from the successful SNO experiment.  The Penn SNO-plus group is led by Professor Josh Klein.


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.


Molecular Electronics

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.
