Eva Wirström

Senior forskare at Chalmers, Space, Earth and Environment, Astronomy and Plasmaphysics, Galactic Astrophysics

Eva Wirström is part of the unit of Galactic Astronomy, under the division for Astronomy and Plasma Physics, and has her office at Onsala Space Observatory. Her research interests includes the physics and chemistry in the giant clouds of gas and dust forming stars and planetary systems in our galaxy, as well as the link between these and the emergence of life - astrochemistry and astrobiology. As senior researcher she works on the Science team for one of the instruments bound for the Jupiter system in ESA's JUICE (JUpiter ICy moons Explorer) mission, the Submillimetre Wave Instrument (SWI). SWI will be used to observe the thin water atmospheres of Jupiter's largest moons, connected to Eva's previous work on interpreting data from the Herschel Space Observatory, which observed the water content in many different kinds of space environments. Eva combines observational studies with development of computer-based models of complex chemical networks under varying physical conditions. Eva's research is funded by two grants from the Swedish National Space Board.
