LIGO SURF and the Perfect Wave

Douglas Smith
As the Advanced LIGO Project geared up last summer, 27 undergraduates from around the world became full partners in one of the biggest, most complex physics experiment ever. Their contributions ranged from creating hardware and software for current use to helping design next-generation detectors.

Alumnus Arthur McDonald Wins 2015 Nobel Prize in Physics

Douglas Smith
Arthur B. McDonald (PhD '70), director of the Sudbury Neutrino Observatory (SNO) in Ontario, Canada, and Takaaki Kajita, at the University of Tokyo, Kashiwa, Japan, have shared the 2015 Nobel Prize in Physics for the discovery that neutrinos can change their identities as they travel through space.

The Topolariton, a New Half-Matter, Half-Light Particle

Rod Pyle
The topolariton is a new half-light, half-matter quasiparticle theorized by Caltech researchers that has unique properties. Topolaritons may one day allow for dramatic advances in a number of technologies.

Summer Interns Return with a World of Experiences

Shayna Chabner McKinney
Caltech undergraduate students returned to campus this week, many after spending the summer working at companies in biotechnology, technology, and finance, among other fields. These students have had the opportunity to learn firsthand about the career opportunities and paths that may be available to them after graduation.

Global Project to Study Cosmic Flashes

Kimm Fesenmaier
The GROWTH network aims to keep astronomers and telescopes unbeaten by sunrise as they study exotic events, such as supernovae. The effort, led by new-faculty member Mansi M. Kasliwal, just received funding under the NSF's Partnerships for International Research and Education program.

Advanced LIGO to Begin Operations

Rod Pyle
The Advanced LIGO, twin observatories designed to detect gravitational waves, begins full-scale operations this week after a 7-year overhaul. The new detectors are 10 times as powerful as their predecessors.

Farthest Galaxy Detected

Rod Pyle
Caltech researchers have reported the detection of the farthest object yet, galaxy EGS8p7. At more than 13.2 billion years old, it provides a fascinating glimpse of the very early universe, just 600,000 years after the Big Bang.

Seeing Quantum Motion

Jessica Stoller-Conrad
Even large objects obey quantum physics, meaning they are never quite at rest. Caltech researchers have developed a way to detect—and manipulate—this underlying quantum motion.

After a Half Century, the Exotic Pentaquark Particle is Found

Rod Pyle
In July, scientists at the Large Hadron Collider (LHC) reported the discovery of the pentaquark, a long-sought particle first predicted to exist in the 1960s by Caltech's Murray Gell-Mann.
