Physics Seminar: “How to Learn to Love the BOSS”

Posted on 9/22/2015 3:50:52 PM

Shirley Ho, assistant professor of Physics at McWilliams Center for Cosmology, Carnegie Mellon University, will present “How to Learn to Love the BOSS” at the Physics Department Seminar on Friday, September 25, at 2:30 p.m. in Weyandt Hall, room 331.

Abstract:

Baryon Oscillations Spectroscopic Survey have just finished surveying 10,000 square degrees, containing over 1 million galaxies within the redshift range of 0.2<z<0.7. I will discuss some of the most recent results from BOSS, including the 1 percent measurement of BAO at z=0.57, and then discuss some of the complications and lessons learned from the BOSS, including effects of non-linear evolution of density fluctuations, and how we learned to deal with them. I will finally put all of this into the context of current and upcoming surveys, including Sloan Digital Sky Survey 4, Dark Energy Spectroscopic Instrument, Large Synoptic Survey Telescope, and WFIRST-AFTA.
