Fermi Improves Its Vision for Thunderstorm Gamma-Ray Flashes
WASHINGTON -- Thanks to improved data analysis techniques and a new operating mode, the Gamma-ray Burst Monitor (GBM) aboard NASA's Fermi Gamma-ray Space Telescope is now 10 times better at catching the brief outbursts of high-energy light mysteriously produced above thunderstorms.
The outbursts, known as terrestrial gamma-ray flashes (TGFs), last only a few thousandths of a second, but their gamma rays rank among the highest-energy light that naturally occurs on Earth. The enhanced GBM discovery rate helped scientists show most TGFs also generate a strong burst of radio waves, a finding that will change how scientists study this poorly understood phenomenon.
Before being upgraded, the GBM could capture only TGFs that were bright enough to trigger the instrument's on-board system, which meant many weaker events were missed...(Read More)

CSPAR - Physics GRA Lauren Kahre takes second place in the physical science category at the 2012 Von Braun Symposium Poster Competition
Motivated by the development of a very general theoretical model describing the transport of turbulence throughout the heliosphere, we present a study of the turbulent and bulk properties of the solar wind. We investigate the bulk plasma flow speed, the bulk plasma density, the magnetic field turbulence and the kinetic turbulence. We use archival Voyager, Helios, and Ulysses data sets to explore low frequency solar wind turbulence properties throughout the heliosphere. We present results that describe the radial scaling of different measures related to magnetic field turbulence and turbulent velocity fluctuations.

NASA IBEX Spacecraft Discovery
CSPAR and Department of Physics Professors Jacob Heerikhuisen, Nick Pogorelov, and Gary Zank were in the news recently. All three had been part of the successful NASA IBEX spacecraft team that had, much to everyone’s considerable surprise last year discovered a giant ribbon of energetic neutral atom emission at the edge of the solar system, leaving researchers mystified. To quote several news articles, the researchers called it a “shocking result” and puzzled over its origin. Now the mystery may have been solved.
In an Astrophysical Journal Letter that appeared on 10 January 2010, Heerikhuisen, Pogorelov, and Zank introduced a new physical process not considered before, and were able to emerge with a compelling explanation only two months after the observation had first been reported. The Figure below shows the correspondence between the observed ribbon feature and that simulated by UAH researchers.
The impact of our simulations has been dramatic (multiple NASA press releases and related news stories), but more importantly presents a concrete demonstration of discovery and explanation through computational modeling in concert with very sophisticated observations. Not only has our approach proved transformational to the space physics community in understanding and modeling complex systems, but it is introducing a new paradigm for space missions by including state-of-the-art simulation and modeling as part of the mission itself. In the same sense that we employ software on an MRI scan to transform the data into a 3D image of the patient for a doctor, the observations returned by IBEX can be understood only by applying state-of-the-art computer simulations to the data to extract knowledge of the physics behind the system.
These two maps show the entire sky in the emission of neutral hydrogen. The energetic neutral atom (ENA) measurements by the IBEX mission (top image) show a ribbon feature spanning the entire sky. With our models, we discovered that this feature can be understood and reproduced (bottom image) after adding an unpredicted "mirror effect". The two images show observed and modeled ENAs, respectively, at comparable speeds [Heerikhuisen et al., 2010]
"Interstellar Boundary Explorer (IBEX)" Published
CSPAR Director Gary P. Zank, together with co-authors Dave McComas and Nathan Schwadron, had a new book published by the well-known scientific publisher Springer. The book, entitled "Interstellar Boundary Explorer (IBEX)", provides the physics background to the mission, summarizing the mission instrumentation and the theory behind the observations that will be made.
Dr. Gary P. Zank "Quest for Excellence Award Winner"
Dr Gary Zank was awarded the 2009 - Quest for Excellence Award. These awards are given each year to publicly recognize outstanding contributions of individuals in the greater Huntsville community in the fields of Science, Technology, Engineering, and Mathematics (STEM). Each year the award highlights a different branch of the STEM arena. The 2009 awards focused on the field of mathematics and were given to members of the scientific, engineering or educational community who bridge the gap between mathematics and its application. This includes work that uses high-level mathematics and/or innovative mathematical tools to solve problems in engineering, science or technology. The award was presented at the Sci-Quest Hands-on Science Center Mad Scientist Ball on Friday, October 23, 2009. In conjunction with this award Dr Zank also received an Alabama House of Representatives resolution adopted in his honor on November 6, 2009.
Dr. Gang Li Recipient of the 2009 International Cosmic Ray Commission
Dr Gang Li is the recipient of the 2009 International Cosmic Ray Commission IUPAP-Young Scientist Prize. The prize was awarded in Lodz, Poland and the citation read “For outstanding contributions towards our understanding of solar energetic particle transport and diffusive shock acceleration in the turbulent solar wind and at interplanetary shocks.” Dr Li’s work represents a major advance in our understanding of the solar cosmic ray problem, and presents an approach of great sophistication to understanding the detailed plasma physics of particle acceleration in the complex environment of the solar wind. The approach for which Dr Li was recognized provides our best opportunity for understanding in situ the detailed mechanics of diffusive shock acceleration as a process and therefore these ideas will find resonance across a broad range of astrophysical problems.
Dr Vladimir Florinski's Winning Proposal
Dr. Vladimir Florinski a CSPAR Researcher and Department of Physics Professor is the recipient of a new 3 year NASA for his proposal entitled, “Structure & Physics of the Global Helioshpere During the Minimum of Solar Cycle 24”. The proposed work focus is on the many aspects of the solar wind observed at 1 AU, which require an understanding of the global heliosphere in its most quiescent state afforded by the unprecedentedly deep 2008-2010 solar minimum. Dr Florinski’ winning proposal will address the physics of these processes through a combination of modeling, theory, and observation. A suite of models and theory developed at the UAHuntsville will be used to better understand solar wind and its interaction with the surrounding interstellar medium. The project aims at solving some of the outstanding problems of space science, including that of the origin of anomalous cosmic rays.
