Astrophysics and cosmology

An excess of gamma rays at the center of the Milky Way, previously discussed as a sign of dark matter, is likely caused by the superdense remains of ancient stars.

Explore the fourth dimension, from processes that occur in billions of years down to tiny slivers of a second.

Join us for five days of ultrafast science from April 17 to 21.

Two astrophysicists and a theoretical physicist discuss how the Large Synoptic Survey Telescope will probe the nature of dark matter and dark energy by taking an unprecedentedly enormous scan of the sky.

Astrophysicists Eric Charles and Mattia Di Mauro discuss the surprising glow of our neighbor galaxy.

Most experiments searching for mysterious dark matter require massive colliders, but Stanford physicist and SLAC collaborator Peter Graham advocates a different, less costly approach.

LSST is currently under construction in Chile. The U.S. Department of Energy’s SLAC National Accelerator Laboratory is leading the construction of the LSST camera – the largest digital camera ever built for astronomy.

What are parallel universes, and why do we think they might exist?

KIPAC’s Ralf Kaehler and Tom Abel contributed two scenes to the science documentary narrated by Brad Pitt and Cate Blanchett.

Underground experiment passes critical DOE review and prepares for startup in 2020.

Three recent studies using data from the Fermi Gamma-ray Space Telescope have expanded the hunt for unexplained signals coming from beyond our galaxy.

A previously detected, anomalously large X-ray signal is absent in new Hitomi satellite data, setting tighter limits for a dark matter interpretation.
