Fall 2019
Neutron stars are some of the densest objects in the Universe, with densities in their cores that are larger than that of the atomic nucleus. Their relatively small size allows them to spin very rapidly, with speeds at the equator that are a large fraction of the speed of light. Being some of the...

In geological sequestration CO2 leakage is a vital concern; consequently monitoring and verifying the subsurface movement and phase behaviour of the injected CO2 is very important to ensure the integrity of the reservoir. Seismic methods are thought to be one way to monitor the changes in...

We study the effects of electron-electron interactions and magnetic fields on surface states of three-dimensional topological insulators (3D TIs). In this work we use an effective Hamiltonian to describe a slab of the 3D TI Bi$2$Se$3$. In the non-interacting limit, and for slab thicknesses...

Spacetime—the union of space and time—is both the actor and the stage during physical processes in our fascinating Universe. In Lorentz invariant local theories, the existence of a maximum signalling speed (the “speed of light”) determines a notion of causality in spacetime, distinguishing the...

Effects of the Large Magellanic Cloud on the Local Dark Matter Distribution in the Milky Way: Insights from the Auriga Simulation
DownloadSpring 2024
This thesis investigates the Large Magellanic Cloud's (LMC) influence on the Milky Way's local dark matter distribution, focusing on implications for dark matter direct detection. Using state-of-the-art Auriga magneto-hydrodynamical simulations with an LMC-like system, we study the dark matter...

Efficient algorithms for least squares wave equation migration and source signature estimation
DownloadFall 2017
Estimating accurate images of the subsurface is one of the end products of seismic data processing. Numerical solutions to the wave equation allow designing linearized forward operators. The adjoint of the linearized forward operator is used to image the interior of the earth. The adjoint...

Elastic Least-squares Reverse Time Migration and Elastic Gauss-Newton Full-waveform Inversion
DownloadFall 2018
With the fast development of high-performance computing resources, imaging and inversion techniques in the exploration geophysics community are moving from simplified methods to more complex methods that honour as far as possible the physics of wave propagation. Multiparameter imaging and...
