Acoustic oscillations arise from the competition between gravitational attraction and gas pressure in the primordial plasma. These oscillations leave their imprint on structures at every epoch of the evolution of the Universe, providing a robust standard ruler from which the expansion histo...

Dark Energy From the Ground Up: Make Way for BigBOSS Several ways have been proposed to examine dark energy, in hopes of finding out just what it is. One of them, "supernovae" for short, certainly works: it's how dark energy was discovered in the first place. Other independent techniques...
