Quasar Absorption Lines: From Reionization to Dark Matter George Becker, Dept. of Physics & Astronomy, UC-Riverside Absorption patterns in the spectra of distant quasars are one of our most powerful probes of cosmic structure. The rich “forest” of lines produced …

The development of X-ray free-electron lasers has enabled new experiments for studying uncrystallized biomolecules that were previously infeasible with traditional X-ray sources.

Among the great surprises of modern cosmology was the discovery of Dark Energy. In this talk, I will introduce the Canadian Hydrogen Intensity Mapping Experiment (CHIME), an ambitious project to study Dark Energy by tracing out 4 billion years of cosmic history, using a purpose-built radio telescope at the Dominion Radio Astrophysical Observatory
