    Abstract : Here I study the “plasma interactions with icy bodies in the solar system”, that is, my quest to understand the fundamental processes that govern such interactions. By using numerical modelling combined with in situ observations, one can infer the internal structure of icy bodies and their plasma environments. READ MORE

  5. 5. Observations with Herschel: High-mass star formation and the search for NH+

    Author : Mitra Hajigholi; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High-mass star: formation - ISM: abundances - ISM: molecules;

    Abstract : The capture and interpretation of the electromagnetic radiation we receive from space is essential to our understanding of the cosmos. When the Earth's opaque atmosphere prevents the far-infrared radiation to reach ground based antennas, space observatories become crucial to collect that important piece of the large puzzle that otherwise would have been lost.
