SUMMARY:Backlighting the large-scale structure with the cosmic microwa
 ve background\, Physics Department Colloquium\, Emmanuel Schaan\, Kavl
 i Institute for Particle Astrophysics and Cosmology (KIPAC)\, Stanford
DESCRIPTION:Upcoming large-scale structure (LSS) and cosmic microwave 
 background (CMB) experiments offer a unique opportunity to turn the Un
 iverse into a particle physics laboratory and determine the nature of 
 dark matter\, dark energy\, and the masses of the neutrinos. I will pr
 esent innovative methods to jointly analyze these datasets and unleash
  their full constraining power. My group's research explores two power
 ful ways of using the CMB as a backlight for the LSS: revealing the in
 visible dark matter (gravitational lensing) and baryons (Sunyaev-Zel'd
 ovich and patchy screening effects) via their shadows on the CMB. Thes
 e methods will yield percent-precision maps of the dark and baryonic m
 atter on cosmic scales\, from combinations of CMB experiments like the
  Atacama Cosmology Telescope\, Simons Observatory and CMB-S4 with LSS 
 experiments like the Dark Energy Spectroscopic Instrument and the Rubi
 n Observatory. These will not only shed light on dark matter\, dark en
 ergy and the neutrinos\, but they will also constrain models of inflat
 ion and transform our understanding or galaxy formation.
