1. Cosmic tests of massive gravity
University dissertation from Stockholm : Department of Physics, Stockholm UniversityAbstract : Massive gravity is an extension of general relativity where the graviton, which mediates gravitational interactions, has a nonvanishing mass. The first steps towards formulating a theory of massive gravity were made by Fierz and Pauli in 1939, but it took another 70 years until a consistent theory of massive gravity was written down.

2. New Techniques for Estimation of Source Parameters Applications to Airborne Gravity and PseudoGravity Gradient Tensors
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : Gravity gradient tensor (GGT) data contains the second derivatives of the Earth’s gravitational potential in three orthogonal directions. GGT data can be measured either using land, airborne, marine or space platforms. READ MORE

3. Stringed along or caught in a loop? Philosophical reflections on modern quantum gravity research
University dissertation from Uppsala : Uppsala universitet, Filosofiska InstitutionenAbstract : A number of philosophical questions, all connected to modern research in quantum gravity, are discussed in this dissertation.The goal of research in quantum gravity is to find a quantum theory for gravitation; the other fundamental forces are already understood in terms of quantum physics.

4. Geoid Model of Tanzania from Sparse and Varying Gravity Data Density by the KTH method
University dissertation from Stockholm : KTHAbstract : Developed countries are striving to achieve a cm geoid model. Most developing countries/regions think that the situation in their areas does not allow even a few decimetre geoid model. GNSS, which provides us with position, is one of the greatest achievements of the present time. READ MORE

5. Making Maps and Keeping Logs Quantum Gravity from Classical Viewpoints
University dissertation from Uppsala : Acta Universitatis UpsaliensisAbstract : This thesis explores three different aspects of quantum gravity. First we study D3brane black holes in CalabiYau compactifications of type IIB string theory. Using the OSV conjecture and a relation between topological strings and matrix models we show that some black holes have a matrix model description. READ MORE
