With two SLAC researchers in the lead, an analysis of the enigmatic Fermi bubbles has narrowed down the number of possibilities for their origin, but hasn't completely solved the puzzle.
Step on a scale and you’ll get a quick measure of your weight. Weighing galaxy clusters, groups of hundreds or thousands of galaxies bound together by gravity, isn’t so easy. But scientists have many ways to do it.
Two dark matter hunters with decades of experience between them are turning SLAC into their base of operations for LZ, the next big dark matter search.
A sensor design first envisioned in 1995 by physicists and engineers at SLAC plays a starring role in a major ATLAS detector upgrade at the Large Hadron Collider.
