Theorists at Durham University simulated the universe using hydrodynamical simulations in which a scalar field enhances gravitational forces in low-density regions.
Cold-atom interferometry could fill a gap in observational capability for gravitational waves in the intermediate-frequency band.
As two white dwarfs orbited one another they slowly lost momentum through the emission of gravitational waves.
The ALICE collaboration is now using the scattering between particles produced in collisions at the LHC to constrain interaction potentials in a new way.
"This book offers a well-balanced introduction to particle and astroparticle physics, requiring only a basic background of classical and quantum physics."
Christian Stegmann, director of DESY’s newly established research division for astroparticle physics, describes the ambitious plans ahead in this vibrant field.
On 10 April, researchers working on the Event Horizon Telescope released the first direct image of a black hole.
Hypotheses are that the Cow was either a compact object being destroyed when coming too close to a black hole, or a special type of supernova in which a black hole or magnetar is produced.
The ATLAS collaboration carried out a first collider search for light scalar particles that could contribute to the accelerating expansion of the universe.
Until recently the number of theories on the origin of fast radio bursts outnumbered the number of observations.
