Des Expanding Universe (01 March 2018)
Since its beginning, our universe has been expanding. The early work of scientists such as Edwin Hubble gave us proof that galaxies across the universe are moving apart from one another. Hubble’s law states, “Objects observed in deep space are found to have a red shift, interpreted as a relative velocity away from Earth.” The Dark Energy Survey (DES) seeks to help unravel the mysteries of what forces are causing this expansion by focusing on dark energy and how it constantly remaps the cosmos.
OSG User School 2017 (29 November 2017)
The OSG User School 2017 was held at the University of Wisconsin–Madison on July 17–21. There were 56 participants, including mostly graduate students, post-doctoral researchers, a few advanced undergraduates, several faculty, and some research staff from research institutions in the United States (and one each from England and Spain). The range of scholarly domains was one of the most diverse yet, including physics, biology, chemistry, medicine, engineering, statistics, earth sciences, plant sciences, and economics. Participants were selected by demonstrating need for large-scale computing and by being in a position to transform their scholarly work through computation. The instructors this year were Bala Desinghu, Brian Lin, and Derek Weitzel from the OSG, plus Christina Koch and Lauren Michael from the UW–Madison’s Center for High Throughput Computing.
On October 16th, scientists at the LIGO and Virgo scientific collaborations announced the detection of gravitational waves from the collision of two neutron stars that occurred 130 million years ago. This collision has also been observed with light emitted across the entire electromagnetic spectrum.
LIGO Collaboration wins 2017 Nobel Prize in Physics (05 October 2017)
On October 1, 2017, Rainer Weiss, Barry Barish, and Kip Thorne were awarded the Nobel Prize in Physics “for decisive contributions to the LIGO detector and the observation of gravitational waves.” LIGO confirmed the first direct observation of gravitational waves on September 14, 2015. Both LIGO detectors, one in Hanford, Washington, and one in Livingston, Louisiana, observed a gravitational wave from the merger of two black holes, and with that, the final piece of Einstein’s general theory of relativity fell into place.
Astronomy archives are creating new science every day (29 August 2017)
Accumulated data sets from past and current astronomy research are not dead. Researchers are still doing new science with old data and still making new discoveries.
Machine learning insights into molecular science using the Open Science Grid Computation has extended what researchers can investigate in chemistry, biology, and material science. Studying complex systems like proteins or nanocomposites can use similar techniques for common challenges. For example, computational power is expanding the horizons of protein research and opening up vast new possibilities for drug discovery and disease treatment.
Understanding the universe has always fascinated mankind. The VERITAS Cherenkov telescope array unravels its secrets by detecting very-high-energy gamma rays from astrophysics sources.
For neuroscientist Chris Cox, the OSG helps process mountains of data (20 February 2017)
Whether exploring how the brain is fooled by fake news or explaining the decline of knowledge in dementia, cognitive neuroscientists like Chris Cox are relying more on high-throughput computing resources like the Open Science Grid (OSG) to understand how the brain makes sense of information.
Free Supercomputing for Research - Scott Cole introduces you to OSG (10 February 2017)
Scott Cole, a neuroscience PhD student at University of California San Diego, wrote an article which appeared in PythonWeekly that details how to get up and running on Open Science Grid. “I was starting to run into computational limitations in my neuroscience research, but I didn’t have any experience speeding up my work with something like high throughput computing,” said Cole. When Cole saw that there was an opportunity at the OSG User School to learn how to use OSG and the free access to resources it provides, he jumped on it.
OSG helps LIGO scientists confirm Einstein’s unproven theory (11 February 2016)
Albert Einstein first posed the idea of gravitational waves in his general theory of relativity just over a century ago. But until now, they had never been observed directly. For the first time, scientists with the Laser Interferometer Gravitational-Wave Observatory (LIGO) Scientific Collaboration (LSC) have observed ripples in the fabric of spacetime called gravitational waves.
Duke University Associate Professor of Physics Shailesh Chandrasekharan and his graduate student Venkitesh Ayyar are using the Open Science Grid (OSG) to tackle notoriously difficult problems in quantum systems.
