1. Experimental Adaptive Optics. A test facility for adaptive optics on a small telescope
Sammanfattning : This thesis presents the work on the design of, construction of, and finally observations with, an experimental setup comprising a small telescope equipped with adaptive optics. The facility has been assembled at Lund Observatory, where also observations on the sky have been made. LÄS MER
2. Extremely Large Telescopes Optical Design and Wavefront Correction
Sammanfattning : An overview of the state of art within optical design of large astronomical telescopes is given. Recent advances within the field are presented. The importance of new computer-controlled mirror-polishing methods is emphasized. LÄS MER
3. Microfabrication of Optical Components in Synthetic Diamond : Infrared Optics for Applications in Astronomy and Spectroscopy
Sammanfattning : Infrared optics is a broad general term, relevant to a range of fields. The manufactured diamond optical components utilized within this thesis were applied to both astronomy, in which direct imaging of star system using large ground-based telescopes and diamond coronagraphs was performed, and in absorption spectroscopy probing solvents and proteins using a tuneable quantum cascade laser and diamond waveguides.

4. Dissociative Recombination of Astrochemically Interesting Ions
Sammanfattning : In this thesis the major work described concerns experimental determination of the dissociative recombination (DR) reaction for several molecular ions of astrochemical interest. DR is the process where an electron recombines with a molecular ion to form an excited neutral that disintegrates into two or more neutral fragments to release the gained excess energy. LÄS MER
5. 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
