Astrophysics and cosmology

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...

A cheap technique could detect neutrinos in polar ice, eventually allowing researchers to expand the energy reach of IceCube without breaking the bank.

Matching up maps of matter and light from the Dark Energy Survey and Fermi Gamma-ray Space Telescope may help astrophysicists understand what causes a faint cosmic gamma-ray glow.

The Large Synoptic Survey Telescope will be named for an influential astronomer who left the field better than she found it.

As the massive LSST camera project reaches its culmination, Hannah Pollek is one of the engineers in the clean room each day putting the pieces together.

His work aims to deepen our understanding of dark matter, dark energy and other secrets of the universe.

The Dark Energy Spectroscopic Instrument begins final testing, setting the stage for a 5-year survey that will analyze the light of 35 million galaxies.

Chemist Ben Ofori-Okai investigates what happens to matter under extreme conditions at microscopic scales to better understand its behavior at massive scales, such as what happens in the Earth’s core.

Scientists are designing a next-generation experiment to map the Big Bang’s relic afterglow.

Early-career physicist Jonathan LeyVa helps build one of the world’s most sensitive dark matter detectors.

Maria Elena Monzani prepares an international team to search for clues to one of the biggest scientific mysteries.

A SLAC/Stanford study of the population of satellite galaxies orbiting the Milky Way provides new clues about the particle nature of dark matter.
