The astrophysicist Tracy Slatyer is searching for faint wisps of dark matter annihilating in the early universe — and perhaps in hiding places closer to home.
The spokesperson for the Laser Interferometer Gravitational-Wave Observatory called it “a promising start to mapping the populations of black holes in our universe.”
What could cause galaxies millions of light years apart to all spew material in the same direction?
The astrophysicist, conceptual writer and host of standing-room-only scientific soirees at a repurposed factory in Brooklyn sees science as a powerful force in culture.
In the new, free-for-all era of dark matter research, the controversial idea that dark matter is concentrated in thin disks is being rescued from scientific oblivion.
A satellite spotted a burst of light just as gravitational waves rolled in from the collision of two black holes. Was the flash a cosmic coincidence, or do astrophysicists need to rethink what black holes can do?
The path from a revolutionary set of equations to the detection of gravitational waves was strewn with obstacles and controversy, explains the physicist Daniel Kennefick — and the struggle continues.
Ripples in space-time have been detected a century after Einstein predicted them, launching a new era in astronomy.
The physicist James Bullock explains how a complicated “dark sector” of interacting particles may illuminate some puzzling observations of the centers of galaxies.
