- About PSI
Dr. Jeff Morgenthaler is using ground-based observations of the Io plasma torus and Io to understand the radial transport of mass in Jupiter's magnetosphere. He has used comets to measure the ionization lifetime of carbon in interplanetary space, the dissociation branching ratios of OH and is working toward a measurement of the lifetime of CO. His work with comets and experience with the diffuse X-ray background has led him to an interest in the diffuse UV background, as observed by the GALEX satellite.
Dr. Morgenthaler received his PhD in 1998 from the University of Wisconsin where he studied the spectrum of the diffuse X-ray background with a Space Shuttle Payload of Opportunity and a sounding rocket employing one of the first single-photon calorimetric X-ray detectors. He was subsequently a National Research Council Fellow at the NASA Goddard Space Flight Center, then a Research Scientist at the University of Washington. In 2009, he joined PSI.
