Occurrence Statistics and Driving Mechanisms of Ionospheric Ultra-Low Frequency Waves Observed by SuperDARN Radars
… Simultaneous observations of Pi2 pulsations from THEMIS spacecraft, midlatitude SuperDARN radars, and ground magnetometers, together with analysis of their longitudinal polarization pattern and azimuthal phase propagation, confirmed that they are consistent with a plasmaspheric virtual resonance …

Crater ice deposits near the south pole of Mars
… craters. Using MOLA topography data, MOC and THEMIS imagery, and SHARAD radar sounding data, we characterize the distribution, morphology, and structure of the deposits. In addition, we examine the effect of the crater microenvironment on the formation and persistence of these deposits, …

Penetration of supernova radioactivities in the solar system
"We investigate the mechanism by which supernova ejecta can penetrate the solar system, and in particular, directly deposit live radioactivities on Earth. This study is motivated by the discovery of live undersea 60Fe from an event 2.8 Myr ago. The 60Fe signal is consistent with a nearby supernova …

Progress towards strong coupling between collisionally blockaded atoms and an optical cavity
In this thesis, I present the motivation and design for an experiment in which to probe the interactions between an atom and a single photon light field. I discuss the relevant technical considerations and many of the physical phenomena that can be tested with this particular experimental system. …

The Origins of Four Paterae of Malea Planum, Mars
Malea Planum is a volcanic plain on the southern rim of Hellas Planitia, the largest impact basin on Mars. Four large circular structures on Malea Planum have traditionally been identified as paterae, or low relief, central vent volcanoes (Plescia and Saunders, 1979). A geologic map was constructed …

Information Theory Analysis of the Solar Wind Magnetic Structures for Space Weather Prediction
<p>Forecasting space weather at Earth is highly complicated, because of the limited measurements of the dynamic processes in the Sun that span multiple temporal, spatial, and energy-scales. The solar wind is a highly structured, multi-scale, evolving plasma and consists of coronal mass ejections …
