expansion of the universe slowly stretching its waves until today it appears as microwave radiation. This is the Cosmic Microwave Background (CMB), a glow still visible in the sky. This glow is almost uniform, but small variations from point to point hold information about the conditions of the universe 13.8 billion years ago. This lecture will introduce the CMB, present the sophisticated cameras we build to observe it, and describe the remote outposts of our planet, including the geographic South Pole, where we deploy these cameras to image the CMB. As we image the CMB in finer and finer detail, in particular its polarization, we hope to improve our understanding of the beginning of the universe and perhaps of time itself.
Brief intro:
in 2015. Ahmed is a member of several scientific teams imaging the Cosmic Microwave Background (CMB) from the South Pole and the Atacama Desert in Chile. He spends his time understanding data from these cameras and devising tricks to build more powerful CMB cameras.
