“Measuring the Beginning of Time From the Bottom of the World”
Cyndia Yu, Stanford University Department of Physics, KIPAC
Measurements of the afterglow of the Big Bang, the cosmic microwave background, have allowed physicists to piece together much of our modern understanding of the origin, composition, and evolution of the Universe. Future measurements hope to answer tantalizing questions ranging from the transient nature of the radio sky to the earliest moments of the Universe itself. I will give a brief introduction to the cosmic microwave background and what we can learn from it. I will then describe some of the telescopes we build to make these measurements and the premiere astronomical observing sites we use to house our experiments.
Cyndia Yu is a PhD student in physics at Stanford, where she works on building new tools to study the astroparticle universe. She is involved in cosmic microwave background (CMB) experiments around the world, including the BICEP/Keck experiment series, the South Pole Observatory, the Simon's Observatory, and CMB-S4, where she has done everything from designing and testing new detector systems to thinking about new ways to analyze CMB data to learn about the Universe. As a National Science Foundation Graduate Research Fellow and Stanford Enhancing Diversity in Graduate Education Fellow, she is especially interested in communicating the joys of her work to diverse audiences and striving to make physics accessible to students of all backgrounds.
