For years, scientists have wondered how the observed afterglow of the Big Bang relates to the distribution of galaxies in our universe. Now, thanks to a new map of dark matter, they have direct evidence that a cold region in the afterglow coincides with the lack of matter in the same patch of the sky.
Whether he is on the side of a mountain or working at the Fermilab Quantum Institute, Cristián Peña likes to explore the unknown and tackle new challenges. Although he spends most of his time working on quantum communication systems for FQI, Peña dedicates time to work on the CMS experiment. His work between the two experiments, while different in practice, are conceptually similar.
