SUMMARY:kSZ tomography and its applications to cosmology - Moritz Munchmey
 er (Perimeter)
DTSTART:20180507T120000Z

CONTACT:Tobias Baldauf
DESCRIPTION:In this talk I will present our recent work on exploring the c
 ross-correlation of CMB perturbations from the kinetic Sunyaev-Zel'dovich 
 (kSZ) effect and large-scale structure surveys\, called kSZ tomography. I 
 will discuss a general bispectrum approach to this cross-correlation\, whi
 ch unifies several previously known methods. I will then focus on using kS
 Z tomography to reconstruct the large-scale velocity field of the universe
 \, and show how to use this reconstruction to improve constraints on fNL l
 ocal non-Gaussianities.
