Particle Astrophysics & Cosmology (PAC)

Nearly 200 guests attended a symposium on fundamental physics to celebrate the former deputy director’s numerous scientific contributions, which continue to have a tremendous impact on our understanding of the subatomic world.

Add some science to your holiday carols.

21 of these "science rafts" will go into the world's largest digital camera for astronomy, which is being assembled and tested at SLAC.

Effort to improve the next generation of gravitational wave detectors includes atomic studies of new and better coatings for LIGO’s mirrors at SSRL.

Around the world, scientists and non-scientists alike celebrated the first international Dark Matter Day.

The astrophysicist is recognized for her leadership, mentorship and innovative work in understanding how galaxies form.

The Advanced LIGO gravitational wave detectors have announced their first observation of a binary neutron star coalescence.

System tests at SLAC continue with 32 light sensors - up from a single one - in a small-scale version of the future experiment, which will use nearly 500 of them.

Instead of searching for dark matter particles, a new device will search for dark matter waves.

The minuscule and the immense can reveal quite a bit about each other.

SLAC and Stanford researchers demonstrate that brain-mimicking ‘neural networks’ can revolutionize the way astrophysicists analyze their most complex data, including extreme distortions in spacetime that are crucial for our understanding of the universe.

The emeritus physicist was honored for the development of novel detectors that have greatly advanced experiments in particle physics, especially BABAR, which looked into the matter-antimatter imbalance of the universe.
