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.


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.


Sudbury Neutrino Observatory

The Sudbury Neutrino Observatory (SNO) is a second generation dedicated solar neutrino experiment which has extended the results of the Penn group with the Kamiokande II detector by measuring three reactions of solar neutrinos to fully resolve the solar neutrino problem.



Professor Bob Hollebeek was the technical lead for the National Library of Medicine sponsored National Digital Mammography Archive, which provides distributed grid systems for medical storage and records handling.  Parallel and distributed computing approaches apply to the analysis of data from many fields including medical, scientific, social, and economic data.


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.
