Tests of Gravity Theories with Pulsar Timing
… for testing gravitational physics in the strong gravity regime around these compact and dense objects. In this dissertation, based on gained timing data from observing campaigns with the Arecibo and Effelsberg telescopes, we will present an update to previous gravity test results from the …

Alternative theories of gravity and their application to cosmology
In this thesis we study extended theories of gravity in the context of cosmology. The first part is dedicated to the application of the theory of dynamical systems, which allow us to investigate the global dynamics of some cosmological models resulting from scalar-tensor and higher-order theories …

Constraining gravitational and cosmological parameters with astrophysical data
… Earth, and show that certain observables of the Gravity Probe B (GPB) experiment can be computed in this framework. We examine a toy model showing how a specific theory in this framework can be constrained by GPB data. We also search for viable theories of gravity where the Ricci scalar R in the …

Compact Objects In Relativistic Theories Of Gravity
… and black holes, in relativistic theories of gravity. We start by studying the role of nuclear physics (encoded in the so-called equation of state) in determining the properties of neutron stars in general relativity. We show that low-mass neutron stars are potentially useful astrophysical …

Gravitational Waves and Inspiraling Compact Binaries in Alternative Theories of Gravity
… I, we briefly review fundamental theories of gravity, performed experimental tests, and gravitational waves. The framework and the methods that we use in our calculations are discussed in Part II. This part includes reviewing the methods of the Parametrized Post-Newtonian: PPN) framework, …
