SUMMARY:The CMB as a backlight - Alexander van Engelen (CITA Toronto)
DTSTART:20190304T130000Z

CONTACT:Tobias Baldauf
DESCRIPTION:Thanks to recent data\, much has been learned from the CMB at 
 the epoch of recombination.  CMB studies are now focussed on two new main 
 goals: using the CMB as a backlight to learn about the formation of struct
 ures at more recent times\; and cleaning out these lower-redshift effects 
 to look for key remaining signals of interest from the recombination epoch
 .  I will discuss current efforts with the ACTPol survey as well as what w
 ill be possible with Simons Observatory and CMB-S4 with a focus on the eff
 ect of gravitational lensing.  I will finish by discussing theoretical wor
 k aimed at some related signals of interest which will be observable with 
 the next generation of surveys.
