Overactive Black Holes Shut Down Star Formation

Marcus Woo

A team of astronomers has found that the most active galactic nuclei—enormous black holes that are violently devouring gas and dust at the centers of galaxies—may prevent new stars from forming.

Notes from the Back Row: "Electrons In Flatland"

Douglas Smith

In James Eisenstein's Watson lecture on January 18, 2012, he uses vivid analogies and nifty animations to lead us through the basics of quantum electronics to his own work with some very bizarre particles—even for quantum mechanics.

Two Galaxies in One

Marcus Woo

Observations from the Spitzer Space Telescope show that the Sombrero galaxy is actually two galaxies in one. With a halo of stars surrounded by the thin edge of a stellar disk, the galaxy resembles a big hat.

Fermi Space Telescope Helps Scientists Narrow Search for Dark Matter

Marcus Woo

Scientists have further narrowed the search for a hypothetical particle that could be dark matter, the mysterious stuff that makes up 80 percent of all the mass in the universe.

Modeling Markets

Marcus Woo

Chris Shannon, the Richard Merkin Professor of Economics and Mathematics, is one of Caltech's newest faculty members. Her research involves developing mathematical models to understand financial markets and other mechanisms that allocate goods, such as auctions.

Astronomers Find Light-Bending Quasars

Marcus Woo

Astronomers have found celestial objects called quasars that bend and distort the light coming from galaxies behind them. The discovery may finally allow astronomers to determine the masses of galaxies that host quasars.

Experiment Observes Elusive Neutrino Transformation

Marcus Woo

An international team of physicists—including several from the California Institute of Technology (Caltech)—has detected and measured, for the first time, a transformation of one particular type of neutrino into another type. The finding, physicists say, may help solve some of the biggest mysteries about the universe, such as why the universe contains more matter than antimatter—a phenomenon that explains why stars, planets, and people exist at all.

Buckyballs in Space

Kimm Fesenmaier

Buckyballs—those odd molecules made up of 60 carbon atoms arranged like hollow spheres—have been found, for the first time, in their solid form in space.

Plasmas Torn Apart

Marcus Woo

Using high-speed cameras to look at jets of plasma in the lab, Caltech researchers have made a discovery that may be important in understanding phenomena like solar flares and in developing nuclear fusion as a future energy source.
