Physics and Astronomy Colloquium
in 131 Physics
Speaker: Tony Tyson, University of California Davis
Subject: The New Digital Sky: Solar System to Dark Energy
Refreshments served in Room 216 Physics at 3:30 p.m.
Fueled by advances in software, microelectronics, and large optics
fabrication, a new type of sky survey is being designed. In a continuous
campaign of 15 second exposures, the Large Synoptic Survey Telescope will
cover the sky to high redshift every week, opening a new window on objects
that change or move on rapid timescales. The superb images from the LSST
will also chart billions of galaxies, providing multiple probes of the
mysterious Dark Matter and Dark Energy. Thirty TB of multi-color images
per night will be transformed into a new view of our four dimensional
universe.
