Dr. Bernd Heber is a full professor (W2) at the Institute for Experimental and Applied Physics of the Christian-Albrechts-Universität of Kiel, Germany. He has expertise in cosmic ray transport, as well as in the analysis and interpretation of energetic particle data acquired by spacecraft (Helios, Ulysses, SOHO, STEREO, Pioneer, Voyager) instrumentation. He has investigated a broad range of problems relating to energetic particles in space, including solar and galactic cosmic ray propagation, shock processes, and the modulation of galactic cosmic rays as well as the cosmic ray interaction with the Earth atmosphere. His research interests also cover the development and optimization of new space instrumentation. He is the PI for energetic particle detectors on Ulysses, SOHO, and STEREO. He is and has been involved in the project studies for POEMS, Interstellar Probe, the Interstellar Heliopause Explorer, the Solar Orbiter and Juice mission.Dr. József Kóta is Senior Research Scientist at the Lunar and Planetary Laboratory of the University of Arizona (Tucson, Arizona, USA). Previously he was at the Central Research Institute for Physics of the Hungarian Academy of Sciences. Dr. Kóta’s research interest is centered around energetic particles, solar wind, and magnetic fields in the Heliosphere. He conducts theoretical and numerical studies on galactic and anomalous cosmic rays, as well as fast neutral atoms (ENAs), which offer a unique tool to probe the remote areas of the heliosphere. He has developed a number of numerical codes to model the transport and acceleration of cosmic rays in the interplanetary magnetic field. He conducted theoretical research to understand the anisotropies of cosmic rays. He has been involved in modeling space weather in the Earth’s environment. The aim of his research is to understand, model, and forecast large solar energetic particle (SEP) events; to understand the mechanism how Coronal Mass Ejections drive a shockand accelerate ions to high (often relativistic) energies. He authored or co-authored ~100 articles in scientific journals. He was Guest Investigator at the Ulysses, Voyager and IBEX Missions. He was one of the co-conveners of the ISSI Workshop "Cosmic Rays in the Heliosphere II".Dr. Rudolf von Steiger is the director of the International Space Science Institute in Bern, Switzerland. His research is primarily about the solar wind, mainly using data from SWICS on Ulysses. He also lectures at the University of Bern, where he earned his PhD in experimental physics in 1988.
