Dark Energy Camera scans ancient skies

DOE/Fermi National Accelerator Laboratory

Scientists wonder why the universe is expanding ever faster. What mysterious force is at work? By recording the light from hundreds of millions of galaxies from a mountaintop in Chile, they hope to find out what's going on.

Argonne develops program for cyber security 'neighborhood watch'

DOE/Argonne National Laboratory
Peer-Reviewed Publication

US Department of Energy laboratories fight off millions of cyber attacks every year, but a near real-time dialogue between these labs about this hostile activity has never existed -- until now. Scientists at DOE's Argonne National Laboratory have devised a program that allows for Cyber Security defense systems to communicate when attacked and transmit that information to cyber systems at other institutions in the hopes of strengthening the overall cyber security posture of the complex.

Fermilab's CDF observes Omega-sub-b baryon

DOE/Fermi National Accelerator Laboratory
Peer-Reviewed Publication

At a recent physics seminar at the US Department of Energy's Fermi National Accelerator Laboratory, Fermilab physicist Pat Lukens of the CDF experiment announced the observation of a new particle, the Omega-sub-b (Ωb). The particle contains three quarks, two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton, and has about six times the proton's mass.

Argonne, UC scientists reach milestone in study of emergent magnetism

DOE/Argonne National Laboratory
Peer-Reviewed Publication

Studying simple metallic chromium, the joint UC-Argonne team has discovered a pressure-driven quantum critical regime and has achieved the first direct measurement of a "naked" quantum singularity in an elemental magnet.

Argonne's Leadership Computing Facility working to get more science per watt

DOE/Argonne National Laboratory
Business Announcement

Cooling a supercomputer consumes more electricity than is required to run the machine, even machines as powerful as the IBM Blue Gene/P -- called Intrepid -- at the US Department of Energy's Argonne National Laboratory. Though Intrepid is one of the fastest and most energy-efficient computers in the world, researchers at Argonne's Leadership Computing Facility are continually looking for ways to further reduce the power needed to operate the machine.

Leading-edge data analytics and visualization enable breakthrough science on Argonne's Blue Gene/P

DOE/Argonne National Laboratory
Business Announcement

Most science research programs that run on high-performance computers like the IBM Blue Gene/P Intrepid at the Argonne Leadership Computing Facility generate enormous quantities of data that represent the results of their calculations. But scientists can also use the ALCF to visualize, explore and communicate their findings as highly accurate simulations and often beautiful images.

Nimbus and cloud computing meet STAR production demands

DOE/Argonne National Laboratory
Business Announcement

The advantages of cloud computing were dramatically illustrated last week by researchers working on the STAR nuclear physics experiment at Brookhaven National Laboratory's Relativistic Heavy-Ion Collider. New simulation results were needed for presentation at the Quark Matter physics conference, but all the computational resources were either committed to other tasks or did not support the environment needed for STAR computations.
