1. Stellar Models in General Relativity
Sammanfattning : Neutron stars are some of the most fascinating objects in Nature. Essentially all aspects of physics seems to be represented inside them. Their cores are likely to contain deconfined quarks, hyperons and other exotic phases of matter in which the strong interaction is the dominant force. LÄS MER
2. Photospheric emission from structured, relativistic jets : applications to gamma-ray burst spectra and polarization
Sammanfattning : The radiative mechanism responsible for the prompt gamma-ray burst (GRB) emission remains elusive. For the last decade, optically thin synchrotron emission from shocks internal to the GRB jet appeared to be the most plausible explanation. LÄS MER
3. Strong Cosmic Censorship and Cosmic No-Hair in spacetimes with symmetries
Sammanfattning : This thesis consists of three articles investigating the asymptotic behaviour of cosmological spacetimes with symmetries arising in Mathematical General Relativity.In Paper A and B, we consider spacetimes with Bianchi symmetry and where the matter model is that of a perfect fluid. LÄS MER
4. Dynamical systems in cosmology and astrophysics
Sammanfattning : General relativity is today an important branch of physics. It has, since its publication at the beginning of this century, changed from being of more mathematical than physical interest to one of the most active experimental fields in physics. LÄS MER
5. Unravelling Consistent Spin-2 Interactions
Sammanfattning : Recently, a unique formulation of a classically consistent theory of massive spin-2 fields has emerged. In this thesis I address a few of the primary questions that arise once such a theory is available. LÄS MER
