SDSS Press Release, October 28, 2003
3D Map of Universe Bolsters Case for Dark Energy and Dark Matter
The SDSS is two separate surveys in one. First, galaxies are identified in 2D images (right). Then, their distance is determined from their spectrum to create a 3D map (left) 2 billion light-years deep. Each galaxy is shown as a single point, the color representing its luminosity. Of 205,443 galaxies in the map, the image shows only those 66,976 galaxies that lie near the plane of Earth's equator.
Astronomers from the Sloan Digital Sky Survey (SDSS) have made the most precise measurement to date of the cosmic clustering of galaxies and dark matter, refining our understanding of the structure and evolution of the Universe.

"From the outset of the project in the late 80's, one of our key goals has been a precision measurement of how galaxies cluster under the influence of gravity", explained Richard Kron, SDSS's director and a professor at The University of Chicago.

SDSS Project spokesperson Michael Strauss from Princeton University and one of the lead authors on the new study elaborated that: "This clustering pattern encodes information about both invisible matter pulling on the galaxies and about the seed fluctuations that emerged from the Big Bang."

The findings are described in two papers submitted to the Astrophysical Journal and to the Physical Review D; they can be found on the physics preprint Web site, www.arXiv.org, on October 28.

Cosmic-ray detector breaks size record
By Belle Dumé
Pierre Auger observatory
Pierre Auger
The Pierre Auger Observatory became the biggest cosmic-ray detector in the world this week with the completion of its hundredth detector. The observatory, which will eventually contain more than 1600 detectors, is still being constructed on a vast plain known as Pampa Amarilla in western Argentina. The project is a collaboration between 14 countries, including Argentina, Brazil, the US and several European nations, and the total cost is $55m.

Director's Corner
Good Morning!
Mike Witherell
Mike Witherell
Twenty years ago this month, the first experiments began taking data at the Tevatron.

In the summer of 1983, I was working with a group of some 35 physicists, writing a proposal to do the first high-statistics, low-background charm experiment using the high-energy photon beams that could be made starting with 800 GeV protons. The news from Fermilab that July that the Tevatron had achieved world-record 512 GeV beams gave us great encouragement that a superconducting accelerator would really work.

In the 20 years since the extraction of those record-setting protons, thousands of physicists have advanced our understanding of the universe using this spectacularly successful instrument. Today, the Tevatron is still the most powerful accelerator in the world. We are now operating the Tevatron at a luminosity 40 times its design value, and we will see further improvements. The CDF and DZero experiments will study data samples that are 50 times as large as those of Run I. They will use these data not only to probe the secrets of the particles and forces of earlier discoveries but to search for the next big discovery-supersymmetry, extra dimensions or something we have not imagined yet.

For 20 years, the Tevatron has helped to explore the universe we live in-and it continues to do so. The special November 1 issue of FermiNews will highlight 20 years of groundbreaking technology and science at the Tevatron. It's a milestone worth celebrating.

Application of LEEDTM Principles to ANL and Fermilab Buildings
The workshop will take place on Friday November 21, 2003 from 8:00 a.m. to noon in Wilson Hall. The workshop will cover:

  • Orientation to Leadership in Energy and Environmental Design (LEEDTM),
  • Baseline comparison of LEEDTM rating system with recent Fermilab projects
  • Sample LEEDTM scorecards from ANL projects
  • Estimated costs for pursuing LEEDTM certification on DOE projects
  • Recommendations for adopting LEEDTM measures into ANL/Fermilab design
Contact Rod Walton or Keith Trychta for more information.
