4D Seminar | Michael Wilson (Berkeley Center for Cosmological Physics) “Current & future large-scale structure constraints on Dark Energy & Inflation”

Seminar Organizer

Event Details

DESI will measure the 3D position of 30 million galaxies during the next five years 
to precisely characterize the nature of Dark Energy with baryon acoustic oscillations & 
redshift-space distortions.  Unique signatures present in the large-scale distribution of
galaxies further limit the level of non-Gaussian fluctuations present in the early Universe
and the mechanism of Inflation by extension. 

I will introduce the DESI experiment, summarise the expected returns and implications for 
our understanding of the Universe, and give a status update on where we are today.  I’ll then 
present the design of a natural successor to DESI focused on the 2 < z < 5 volume that promises 
to deliver the same advancements for Inflation that DESI will achieve for Dark Energy.
