LIGO and Virgo Detect Neutron Star Smash-Ups

On April 25, 2019, the National Science Foundation’s Laser Interferometer Gravitational-Wave Observatory (LIGO) and the European-based Virgo detector registered gravitational waves from what appears likely to be a crash between two neutron stars—the dense remnants of massive stars that previously exploded.

Detector R&D

Theory

Nikhef’s Theoretical Physics group performs theoretical research on a wide range of fundamental topics in high-energy physics, ranging from particle and astroparticle physics to cosmology, gravitational waves and string theory.

Physics Data Processing

Advanced computing for physics and other sciences. Nikhef researchers are mainly developing increasingly better grid software, and transferring their grid knowledge, so that  scientists who are struggling with an ‘impossible’ data problem can profit from the grid.

Astroparticle physics

Astroparticle physics combines physics and astronomy. In the cosmos, very strong magnetic fields create what can be considered a ‘natural’ particle accelerator. To perform astrophysics research, scientists ‘just’ need to build the right detectors.

Particle Physics

In particle physics, very large detectors are used to study elementary particles. Particles such as protons are accelerated in a particle accelerator, and made to collide with each other. The detectors record these collisions, which release a lot of energy to create new particles. Nikhef is active in Auger, KM3NeT, Advanced Virgo and XENON1T.

Interview: In it for the long haul

We have conquered the easiest challenges in fundamental physics, says Nima Arkani-Hamed. The case for building the next major collider is now more compelling than ever.
