Bernhard Mistlberger has developed new methods to make Standard Model predictions more precise than ever. The European Physical Society recently awarded him the 2021 Gribov Medal for his contributions.
An analysis of the first three years of Dark Energy Survey data is consistent with predictions from the current best model of the universe. Nevertheless, hints remain from DES and other experiments that matter in the current universe is a few percent less clumpy than predicted.
Rebecca Leane and colleagues showed dark matter could heat planets in our galaxy to incredible temperatures. Here, she explains how that works and how it could pave the way for sensitive new searches for the mysterious substance.
SLAC cosmologists are using multiple images of the same quasars, produced by massive galaxies’ gravitational pull, to calibrate cosmic distances. Their work may help resolve long-standing debates about how quickly the universe is expanding.
Just like we orbit the sun and the moon orbits us, the Milky Way has satellite galaxies with their own satellites. Drawing from data on those galactic neighbors, a new model suggests the Milky Way should have an additional 100 or so very faint satellite galaxies awaiting discovery.
