A Laboratory researcher’s paper published in November 2008 is a cowinner of this year’s American Association for the Advancement of Science Newcomb Cleveland Prize. The
paper is one of two outstanding papers published in Science from June 1, 2008, through May 31, 2009.
Bruce Macintosh of the Physical and Life Sciences Directorate is one of the lead authors for the paper entitled “Direct Imaging of Multiple Planets Orbiting the Star HR 8799,” which appeared in the November 28, 2008, edition of Science. Christian Marois, a former Livermore postdoctoral researcher now at the National Research Council’s Herzberg Institute of Astrophysics in Canada, is the other lead author.
The Macintosh–Marois paper details how astronomers for the first time took snapshots of a multiplanet solar system, much like ours, orbiting another star. The new solar system orbits a dusty young star named HR 8799, which is 140 light years away and about 1.5 times the size of our Sun. Three planets, roughly 7 to 10 times the mass of Jupiter, orbit the star.
Another paper entitled “Images of an Exosolar Planet 25 Light-Years from Earth,” which also appeared in the November 28, 2008, edition of Science, shares the award. That paper includes Livermore author Mike Fitzgerald of the Physical and Life Sciences Directorate, with Paul Kalas of the University of California at Berkeley as the lead author.
Laboratory physicist Ramona Vogt has been selected vice-chair of the American Physical Society (APS) Topical Group on Hadronic Physics. She is the first woman to serve in this position. As a Livermore postdoctoral researcher from 1989 to 1991, Vogt worked in the Heavy Ion Group, predicting heavy particle and lepton pair production rates in nucleus–nucleus collisions at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory. She later returned to Livermore in 2007 as a staff scientist in the Physical and Life Sciences Directorate. Currently, her work involves modeling fission, event by event, using Monte Carlo methods. Another area of interest is heavy quark–related physics at RHIC.
The Topical Group on Hadronic Physics is one of the APS units helping to fulfill the organization’s mission to “advance and diffuse the knowledge of physics.” Topical groups provide opportunities for members to interact with colleagues with similar interests and to keep abreast of new developments in
their specialized fields.
The Laboratory’s Terascale Simulation Facility (TSF) has received a Leadership in Energy and Environmental Design (LEED) gold level certification under the U.S. Green Building Council rating system. LEED is an internationally recognized certification system providing third-party verification that a building or community was designed and built using strategies aimed at improving performance in areas such as energy savings, water efficiency, and carbon dioxide emissions reduction.
“This is truly a noteworthy achievement for NNSA [National Nuclear Security Administration] and LLNL [Lawrence Livermore National Laboratory] that symbolizes our commitment to transforming the Cold War–era nuclear weapons complex into a modern, efficient nuclear security enterprise,” said Brigadier General Garrett Harencak, NNSA principal assistant deputy administrator for Military Application, in a congratulatory communication. Completed in late 2004, TSF is a 23,500-meter-square building that houses some of the world’s fastest supercomputers, including Dawn (BlueGene/P), BlueGene/L, and ASC Purple—Advanced Simulation and Computing (ASC) systems largely dedicated to stockpile stewardship.
