Description
In this talk, I will present the first power spectrum upper limits from the Hydrogen Epoch of Reionization Array (HERA), a purpose-built 21 cm experiment under construction in South Africa. I will highlight several of the supporting efforts---especially calibration and systematics mitigation---that build confidence in our result and in our instrument more generally. Finally, I will discuss how this milestone for the HERA team fits into our broader quest to detect and characterize the 21 cm power spectrum from the Cosmic Dawn and how such a measurement will complement CMB-S4.
