1. 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
2. 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
3. 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
4. Chemodynamics in Star-Forming Molecular Clouds
Sammanfattning : Stars are fundamental building blocks of galaxies. However, the answers to many basic questions about their formation remain elusive. There is no consensus on a theory that can predict the rate of star formation, its clustering properties, and the conditions needed for massive stars to be born. LÄS MER
5. Ultrafast dynamics of small quantum systems studied using electron-ion coincidence spectroscopy
Sammanfattning : Studying how small quantum systems, like molecules and clusters, interact with X-rays is crucial to understanding the ultrafast processes that occur in nature on incredibly short timescales, ranging from femtoseconds to picoseconds. X-rays excite small quantum systems to unstable core hole states, leading to a cascade of phenomena, including Auger decay, nuclear rearrangement, and dissociation. LÄS MER
