11. Formation of small molecules in space through the process of radiative association
Sammanfattning : This thesis is dedicated to calculating the reaction rate constants for the formation of molecules through radiative association (RA) under interstellar conditions. The molecules that have been studied are CH, AlCl, Na+ − H2 and Al+ − H2. LÄS MER
12. On the formation of small molecules by radiative association
Sammanfattning : This thesis is devoted to the theoretical investigation of radiative association, which is one of the processes contributing to formation of molecules in the interstellar medium. The formation of the CN, SiN, SiP and CO molecules through radiative association of the corresponding atoms in their ground electronic states is studied by the means of classical and quantum dynamical calculations.

13. Astrochemical Investigations of Complex Organics in Cold Molecular Cloud Cores
Sammanfattning : Astrochemistry is the study of the formation and evolution of molecules in the interstellar medium (ISM) of the Milky Way and other galaxies. Molecules start to accumulate in the coldest and densest regions of the ISM, namely molecular clouds, and as of this date, 307 interstellar molecules are identified. LÄS MER
14. Studies in Molecular Astrophysics and Astrobiology
Sammanfattning : The molecules of the interstellar medium (ISM) can be used as probes of the physical conditions in a range of different types of interstellar environment, for example star forming regions. The first chapters of this thesis describe the theory and the observational techniques used to study the rotational transition emission from, and the present knowledge of, these molecules. LÄS MER
15. Observations with Herschel: High-mass star formation and the search for NH+
Sammanfattning : 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.
