NASA Names Astrophysics Fellowship For Iconic Woman Astronomer

August 30, 2011 Leave a comment

NASA has established an astrophysics technology fellowship named for the woman many credit as one of the key contributors in the creation of the Hubble Space Telescope.

The Nancy Grace Roman Technology Fellowship in Astrophysics is designed to foster technologies that advance scientific investigations in the origin and physics of the universe and future exoplanet exploration. The fellowship will help early career researchers develop innovative technologies to enable scientific breakthroughs, while creating the skills necessary to lead astrophysics projects and future investigations.

Discovery Sheds Light on Ecosystem of Young Galaxies

August 30, 2011 Leave a comment

A team of scientists, led by Michael Rauch from the Carnegie Observatories, has discovered a distant galaxy that may help elucidate two fundamental questions of galaxy formation: How galaxies take in matter and how they give off energetic radiation. Their work will be published in the Monthly Notices of the Royal Astronomical Society.

First Simulation to Create a Milky Way-like Galaxy

After nine months of number-crunching on a powerful supercomputer, a beautiful spiral galaxy matching our own Milky Way emerged from a computer simulation of the physics involved in galaxy formation and evolution. The simulation by researchers at the University of California, Santa Cruz, and the Institute for Theoretical Physics in Zurich solves a longstanding problem that had led some to question the prevailing cosmological model of the universe.

“Previous efforts to form a massive disk galaxy like the Milky Way had failed, because the simulated galaxies ended up with huge central bulges compared to the size of the disk,” said Javiera Guedes, who recently earned her Ph.D. in astronomy and astrophysics at UC Santa Cruz and is first author of a paper on the new simulation, called “Eris.” The paper has been accepted for publication in the Astrophysical Journal.
