LSST Tutorials for Experimental Particle Physicists

February 1-2, 2006


WHAT: A set of tutorials aimed at an audience of experimental particle physicists (EEP) who are interested in or committed to the Large Synoptic Survey Telescope as their next experiment. The  speakers ranged from experts to fellow EPP-types who are one step ahead in a particular area.

WHEN: Wednesday, February 1, 2006: 1 p.m. to 5 p.m., followed by no-host group dinner.
           Thursday, February 2, 2006: 8:30a.m. to 4 p.m., followed by weekly astro seminar at 4:15 p.m.

These tutorials were organized by: Pat Burchat, Klaus Honsheid and Steve Kahn.

Useful references at an appropriate Level for non-experts:

1. Lecture notes from a course given by Gary Bernstein at U Penn in 2004:
Astronomy 503--Astronomical Methods and Instrumentation

Note from Gary: "No warrantees are offered on my course notes(!). But I would like to know of errors that are found."

2. Excellent write-up of lectures from the 33rd Saas-Fee Advanced Course on Gravitational Lensing.
Authors are Peter Schneider, Chris Kochanek and Joe Wambsganss. These lectures were delivered in 2003, but the write-ups include references from 2004. There are separate chapters on introduction to gravitational lensing and cosmology, strong lensing, weak lensing and microlensing.

3. Modern introductory textbook on cosmology at the advanced undergraduate level:
"Introduction to Cosmology" (2003), Addison Wesley, by Barbara Ryden.

4. Modern textbook on cosmology at the graduate level:
"Modern Cosmology" (2003), Academic Press, by Scott Dodelson.
Chapter 11 discusses data analysis for CMB and large-scale structure.
See reviews of this book.

Weak Lensing, David Wittman
Weak lensing review at the first-year graduate student level.
