Fundamental physics

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.

How do scientists know what percentages of the universe are made up of dark matter and dark energy?

The Dark Energy Spectroscopic Instrument will measure light from 35 million cosmic objects for new insights into what causes the universe to expand faster and faster.

The scientists develop methods to study neutrinos from star explosions and search for unknown particles and forces with possible ties to dark matter.

The Standard Model is far more than elementary particles arranged in a table.

The first website to be hosted in the US has grown to be an invaluable hub for open science.

In its final run, the LUX experiment increased its sensitivity four-fold, but dark matter remains elusive.

Before Hitomi died, it sent back X-ray data that explain how turbulent motions may prevent cooling of hot gas.

Project Poltergeist led to the discovery of the ghostly particle.
