Christina Cohen is a senior scientist at the California Institute of Technology and is involved in the design, calibration, and analysis of several energetic particle instruments. Using data from instruments on the Parker Solar Probe, Advanced Composition Explorer, and the Solar Terrestrial Relations Observatory, she studies the variation of characteristics of solar energetic particle events and energetic storm particle events as a function of time, solar longitude, and radial distance. Understanding such events is key to developing a capability for predicting space weather hazards. She has previously studied the characteristics of heavy ions in the Jovian magnetosphere, using data from the Galileo spacecraft, and the composition of the solar wind, using data from the Ulysses spacecraft.


Momentous Crossing of a Solar Boundary

The Parker Solar Probe has entered, for the first time, the Sun’s magnetic atmosphere, where it started to gather data that could help researchers solve some of the greatest mysteries of solar physics. Read More »
