UC Santa Cruz professor shares one of cosmology's highest honors with Alex Filippenko at UC Berkeley and Ken Nomoto at the ...

Once dismissed as empty expanses between galaxies, cosmic voids are becoming one of the most promising tools for probing the ...

For centuries, cartographers have sought to map Earth’s land masses and seas to better understand the world and their place in it. Now, astrophysicists have taken a major step toward doing the same ...

A longstanding goal in physics has been to link general relativity with quantum theory and so unify the forces of nature. Theories of quantum gravity, however, are plagued by the weak theoretical ...

Astroparticle physics and particle cosmology unite the study of fundamental interactions with observations of the Universe. By tracing high-energy particles and quantum fields across cosmic history, ...

The Numerical Astrophysics Facility emphasizes theoretical and numerical studies of stars, star clusters, the early universe, galaxy distributions, cosmology modeling, and gravitational lensing. The ...

Apply physical laws to the working of the cosmos, and work in the largest laboratory there is: the universe itself. Through the study of astrophysics, researchers learn about the origin, structure, ...

Cosmologists face a dilemma. The rise of quantitative cosmology, exemplified by the release of new data in March on the cosmic microwave background from the WMAP satellite (see pp16-19; print version ...
