SLUO Meeting to Discuss Future of
Particle (Astro)Physics at SLAC

The SLAC Users Organization (SLUO) annual meeting is a perfect opportunity to bring yourself up to date with current and future activities at SLAC in particle and particle astrophysics.

"This year's agenda is future-oriented, and should be of great interest to all," said SLUO Chair Frank Porter. "Everyone at the lab is encouraged to come to some or all of this meeting."

The meeting, which takes place today from 1:30 to 6:00 p.m. in the Panofsky Auditorium, features several presentations, including one from Robin Staffin, Director of the Office of High Energy Physics in the Office of Science. Over the telephone, Staffin will offer his view of the future state of high energy physics research. Take this opportunity to listen to what Staffin has to say and ask him questions.

The full program is available on the SLUO webpage.

Dust may seem to be nothing but a nuisance in daily life, but in structure formation in the early universe, it's extremely important.

Recent work by Tom Abel's group at the Kavli Institute for Particle Astrophysics and Cosmology has centered around simulations of the "firsts": the first stars in the universe and the subsequent formation of the first galaxies. In one of the group's many areas of research, my colleague John Wise has been studying the transition between the first stars and the first galaxies.

Currently, I am working with Wise and Matthew J. Turk to study how the supernova explosions of the first very massive stars affected their very nearby environment. As these stars exploded, they distributed all of the energy and elements that later shaped the formation of the first galaxies. If the stars released dust in addition to energy and elements in their molecular form, its presence could have affected how the first galaxies formed. This is because dust is very efficient in cooling a cloud of gas, and the temperature of the cloud helps determine how they form.

By running high-resolution computer simulations of the inside of stars during their explosive phase, and then working with Wise and Turk to connect these to their simulations of larger galactic-scale structures, we may soon have a consistent view of the early stars and galaxies from the very small to the very large scale.

Vacancies in the DOE Office of Science


The U.S. Department of Energy's Office of Science is seeking highly qualified candidates with outstanding scientific achievements to fill two important positions: Deputy for Programs and Associate Director of the Office of Science Biological and Environmental Research (BER) Program.

The Office of Science is the single largest supporter of basic research in the physical sciences in the United States, with a 2007 budget of $3.8 billion. It oversees the Nation's research programs in high-energy and nuclear physics, basic and fusion energy sciences, and biological, environmental and computational sciences. The Office of Science is the Federal Government's largest single funder of materials and chemical sciences, and it supports unique and vital parts of U.S. research in climate change, geophysics, genomics, life sciences, and science education.

The Office of Science also manages 10 world-class laboratories (including SLAC) and oversees the construction and operation of some of the Nation's most advanced R&D user facilities, located at national laboratories and universities. These include particle and nuclear physics accelerators, synchrotron light sources, nanoscale science research centers, neutron scattering facilities, bio-energy research centers, supercomputers and high-speed computer networks.
