SB/BNL Joint Cosmo seminar (at Stony Brook) [Note special day]: Shirley Ho, Carnegie Mellon: "How I learn to love the BOSS and beyond"

Wednesday 10 Feb 2016, 14:30 → 15:30 US/Eastern

Universe

Baryon Oscillations Spectroscopic Survey (BOSS) has finished surveying 10,000 square degrees, containing over 1 million galaxies within the redshift range of 0.2<z<0.7.  This large number of galaxies allow us to not only probe the expansion of the Universe via Baryon Acoustic Oscillations, but they also enable a whole host of science that was not possible before. 

 

I will discuss some of the recent results from BOSS including the 1% measurement of BAO at z=0.57 and then discuss some of the complications and lessons learned from the BOSS.  I will then move on to present science that was not possible before: placing the first ever constraint on gravity at scales beyond 50 Mpc/h (up to 150Mpc/h), and probing the missing baryons using kinetic Sunyaev Zeldovich effects for the first time when combining with CMB dataset. 

 

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.
