Matias Zaldarriaga

Matias Zaldarriaga, Professor in the School of Natural Sciences since 2009, has made many influential and creative contributions to our understanding of the early universe, particle astrophysics, and cosmology as a probe of fundamental physics. Much of his work centers on understanding the clues about the earliest moments of our universe encoded in the Cosmic Microwave Background, the faint glow of radiation generated by the Big Bang, and in the distribution of matter in the late universe.

On September 14, 2015, the two detectors of the Laser Interferometer Gravitational-Wave Observatory (LIGO) observed a gravitational-wave signal from the merger of a pair of black holes. While this impressive technological triumph was celebrated...

Albert Einstein’s general theory of relativity, a pillar of modern physics formulated 100 years ago, was celebrated by the Institute for Advanced Study and Princeton University in a two-day conference, General Relativity at 100. The conference,...

“Space Ripples Reveal Big Bang’s Smoking Gun,” read the New York Times headline last March 17. In a seemingly momentous news conference at the Harvard–Smithsonian Center for Astrophysics, researchers using a BICEP (Background Imaging of...

In the public lecture “The Latest News from the Cosmos,” Matias Zaldarriaga, Professor in the School of Natural Sciences, explores the most detailed map of the infant universe to date. Publicly released on March 21, 2013, the...
