Simulations of remote sensors are used to understand how spacebased observations can be best applied to studying the Earth as a system. Astrophysics X-Ray Astronomy. The research includes experiments covering the 30 KeV to 10 MeV region to study gamma ray bursts and other transients sources, pulsars, and to study the variability and spectra of known sources. Present activities include analysis of data from the Burst and Transient Source Experiment on the Gamma Ray Observatory, and the development of new balloon-borne instruments. The research is carried out with emulsion chambers and with electronic counters, exposed on balloons at about 40 kilometers altitude for up to two weeks.
Research includes laboratory work, data analysis.
Plasma and gas dynamic processes are studied by means of in situ plasma and neutral particle measurements, and by remote optical and electromagnetic sensing of the constituent plasmas and gases. Activities include design, development, and calibration of flight instrumentation, with analysis and interpretation of the resulting data in terms of physical models. The influence of the magnetic field on the development and evolution of solar atmospheric structure is studied. The primary data are vector magnetograms obtained at Marshall's Solar Observatory. These observations are complemented by theoretical studies to characterize the nonpotential nature of these fields.
