6. Studies of late-type stars and massive star formation regions using masers
Sammanfattning : .... LÄS MER
7. H2S and dense gas in luminous infrared galaxies and their outflows
Sammanfattning : Luminous infrared galaxies (LIRGs) are dusty galaxies that are going through an important and likely transient phase in their evolution. They experience rapid growth through bursts of star formation or an accreting supermassive black hole, an Active Galactic Nucleus (AGN). LÄS MER
8. Chemodynamical Simulations of Star-Forming Molecular Clouds
Sammanfattning : Stars are known to form from dense, dusty clumps and cores of molecular clouds. However, there is no consensus on a theory that can predict the rate of star formation, its clustering, and the conditions needed for massive stars to be born. A major challenge is how to observe and characterise the gas that is the fuel for star formation. LÄS MER
9. Astrochemistry at Millimetre and Submillimetre Wavelengths
Sammanfattning : The focus of this thesis is a series of observational tests, aiming to clarify the chemical and physical origin of interstellar molecules. Spectral lines at millimetre and submillimetre wavelengths, caused by rotational transitions in CO, H2O, NH3, CH3OH, CH3SH, C2H3CN, and several of their isotopologues, have been observed towards regions of star-formation in the Galaxy.

10. 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.
