1. Information geometries in black hole physics
Sammanfattning : In this thesis we aim to develop new perspectives on the statistical mechanics of black holes using an information geometric approach (Ruppeiner and Weinhold geometry). The Ruppeiner metric is defined as a Hessian matrix on a Gibbs surface, and provides a geometric description of thermodynamic systems in equilibrium. LÄS MER
2. Physics-informed inferences of galaxy clustering with Bayesian forward modelling
Sammanfattning : In this thesis, we showcase four novel approaches to constraining the relationship between cosmological observables and the large-scale structure. The majority of the energy content of the Universe in the concordance cosmological model remains largely unknown. LÄS MER
3. Investigation of Polar Mesosphere Summer Echoes in Northern Scandinavia
Sammanfattning : This PhD thesis deals with phenomena which are closely related to the unique thermal structure of the polar summer mesosphere, namely Polar Mesosphere Summer Echoes (PMSE). PMSE are strong radar echoes commonly observed by VHF MST radars from thin layers in the 80-90 km altitude interval at high latitudes during summer. LÄS MER
4. On the Formation and Physical Behaviour of Exhaled Particles
Sammanfattning : Aerosol particles are generated in human airways and leave the body with exhaled air. The particles originate from the respiratory tract and contain non-volatile compoundsthat potentially may be used as biomarkers for various medical conditions. To utilise any information provided by the particles, they must be characterised. LÄS MER
5. Thermophysical Modelling and Mechanical Stability of Cometary Nuclei
Sammanfattning : Comets are the most primordial and least evolved bodies in the Solar System. As such, they are unique sources of information regarding the early history of the Solar System. However, little is known about cometary nuclei since they are very difficult to observe due to the obscuring coma. LÄS MER
