SUMMARY:New Probes of Old Structure: Cosmology with 21cm Intensity Mapping 
	and the Cosmic Microwave Background
DESCRIPTION:Featuring Laura Newburgh\, Yale University\nHosted by: Indara S
	uarez\n\nPart of the HEE Seminar Series.\n\nCurrent cosmological measuremen
	ts have left us with deep questions about our Universe: What caused the exp
	ansion of the Universe at the earliest times? How did structure form? What 
	is Dark Energy and does it evolve with time? New experiments like CHIME\, H
	IRAX\, and ACTPol are poised to address these questions through 3-dimension
	al maps of structure and measurements of the polarized Cosmic Microwave Bac
	kground. In this talk\, I will describe how we will use 21cm intensity meas
	urements from CHIME and HIRAX to place sensitive constraints on Dark Energy
	 between redshifts 0.8 -- 2.5\, a poorly probed era corresponding to when D
	ark Energy began to impact the expansion history of the Universe. I will al
	so discuss how we will use data from new CMB instruments to constrain cosmo
	logical parameters like the total neutrino mass and probe structure at late
	 times.
