Galaxies on FIRE: Star Feedback Results in Less Massive Galaxies

Jessica Stoller-Conrad

By incorporating the data of individual stars into whole-galaxy models, Caltech researchers can look at the actual effects of star feedback in the galaxies they study.

From Spinning Black Holes to Exploding Stars: A New View of the Energetic Universe

Douglas Smith

The Nuclear Spectroscopic Telescope Array, or NuSTAR, sees the high-energy X-rays emitted by the densest, hottest regions of the universe. Professor Harrison will describe NuSTAR's unlikely journey and share some of its remarkable results.

Peering Through the Intergalactic Dust

Cynthia Eller

Where do you go to look at the stars? Away from city lights, certainly. But if you're serious about peering far out into space, to the observable edges of our universe, at submillimeter wavelengths, you have to do a little better than that.

Interactions in Space: An Interview with Philip Hopkins

Jessica Stoller-Conrad

"I work on a broad range of topics, but basically I like studying how big things form. I study how galaxies form, how stars form, and how supermassive black holes form. Recently, I started studying how planets form"

John H. Schwarz Wins Physics Frontiers Prize

Cynthia Eller

Schwarz and Michael B. Green of the University of Cambridge were honored for developing superstring theory during their collaboration between 1979 and 1986. The prize comes with a $300,000 award and eligibility for the 2014 Fundamental Physics Prize, which, at $3 million, is one of the largest academic prizes in the world.
