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.

 

Dark Energy Studies

Professor Masao Sako uses Type Ia supernovae to study the expansion history of the universe.  The graphs show (left and middle) Hubble diagrams from a simulated 5-year Type Ia sample from the Dark Energy Survey.  The right graph shows the 95% confidence limits on dark energy parameters.

The Epoch of Reionization

 

Astrophysicists are interested in tracing the development of large scale structure during the so-called Epoch of Reionization - the period in the history of the universe in which the first luminous sources turn on and ionize neutral hydrogen in their vicinity.  Prof. Adam Lidz studies the theory of how to detect and gain information from radition emitted during this period.

 

Master of Medical Physics

The Department of Physics and Astronomy in the School of Arts and Sciences, in conjunction with the Departments of Radiology and Radiation Oncology in the School of Medicine, offers the Master of Medical Physics degree. The program is intended for technically prepared college graduates who seek to combine their interests in graduate physics with growing career opportunities in the field of medicine.

 

Euclid Mission to Explore Dark Energy

Euclid is an ESA mission to map the geometry of the dark Universe. The mission will investigate the distance-redshift relationship and the evolution of cosmic structures.  Penn researchers are part of the Euclid science team.
