Astra supercomputer at Sandia Labs is fastest Arm-based machine on TOP500 list

ALBUQUERQUE, N.M. — Astra, the world’s fastest Arm-based supercomputer according to the TOP500 list, has achieved a speed of 1.529 petaflops, placing it 203rd on a ranking of top computers announced at The International Conference for High Performance Computing, Networking, Storage, and Analysis SC18 conference in Dallas. A petaflop is a unit of computing speed […]

Wind tunnel and lasers provide hypersonic proving ground at Sandia National Laboratories

ALBUQUERQUE, N.M. — It’s about speed, and Sandia National Laboratories, with a hypersonic wind tunnel and advanced laser diagnostic technology, is in an excellent position to help U.S. defense agencies understand the physics associated with aircraft flying five times the speed of sound. With potential adversaries reporting successes in their own programs to develop aircraft […]

A splash of detergent makes catalytic compounds more powerful

ALBUQUERQUE, N.M — Researcher David Rosenberg examines images of a white powder under a powerful scanning electron microscope. Up close, the powder looks like coarse gravel, a heap of similar but irregular chunks. Then he looks at a second image — the same material produced by colleague Hongyou Fan instead of purchased from a catalog […]

‘Impactful Times’ tells story of decades of Sandia shock physics research

ALBUQUERQUE, N.M. — Mark Boslough and Dave Crawford of Sandia National Laboratories predicted the Hubble telescope could see a rising plume as comet Shoemaker-Levy 9 crashed into Jupiter in 1994. Their prediction, however, went against the prevailing thought that the impact would be a visual fizzle since it would happen on the planet’s far side. […]

Black hole models contradicted by hands-on tests at Sandia’s Z machine

ALBUQUERQUE, N.M. — A long-standing but unproven assumption about the X-ray spectra of black holes in space has been contradicted by hands-on experiments performed at Sandia National Laboratories’ Z machine. Z, the most energetic laboratory X-ray source on Earth, can duplicate the X-rays surrounding black holes that otherwise can be watched only from a great distance and then theorized […]

World’s smallest neutrino detector finds big physics fingerprint

Sandia part of COHERENT experiment to measure coherent elastic neutrino-nucleus scattering LIVERMORE, California — Sandia National Laboratories researchers have helped solve a mystery that has plagued physicists for 43 years. Using the world’s smallest neutrino detector, the Sandia team was among a collaboration of 80 researchers from 19 institutions and four nations that discovered compelling […]

Origin of spooky meteor noises reappraised by Sandia researchers

ALBUQUERQUE, N.M. — When a meteor is about to conk your neighborhood and gives fair warning by emitting sizzling, rustling and hissing sounds as it descends, you might think that the universe is being sporting. But these auditory warnings, which do occur, seem contrary to the laws of physics if they are caused by the […]

Four Sandia researchers named American Physical Society fellows

ALBUQUERQUE, N.M — Four Sandia National Laboratories researchers have been named fellows of the American Physical Society (APS) for outstanding contributions to physics. The awardees are: François Léonard: for fundamental studies of the physics of nanoscale electronic devices. Andrew Landahl: for outstanding leadership and conscientious service to the quantum information community and pioneering contributions to quantum computing […]

Path to success: Sandia women honored for leadership, science

ALBUQUERQUE, N.M. — Two women at Sandia National Laboratories were recognized by professional organizations for their leadership and groundbreaking scientific research. The Society of Women Engineers (SWE) recently gave Sandia President and Laboratories Director Jill Hruby —  the first woman to lead a national security laboratory —  its 2016 Suzanne Jenniches Upward Mobility Award and […]

Sandia researcher wins high-voltage award

ALBUQUERQUE, N.M. — Awards arrive at different levels of intensity, but no one can deny that Sandia National Laboratories researcher Mark Savage has won the highest voltage prize of all — the IEEE William G. Dunbar Award — for work achieved at extremely high voltage. Asked why he was selected for the honor, Savage quipped, […]
