Abstract: N-body simulations provide most of our insight into the structure and evolution of galaxies, but our analyses of these are often heuristic and from simple statistics. We propose a method that discovers the dynamics in… read more here.

DOI: 10.1093/mnras/staf2118
Abstract: The Milky Way is known to contain a stellar bar, as are a significant fraction of disc galaxies across the universe. Our understanding of bar evolution, both theoretically and through analysis of simulations indicates that… read more here.

Abstract: Diffractions generated by the wavefield response of small-scale discontinuous geological bodies carry a wealth of information regarding complex geological structures, which can be used for high-resolution imaging. However, the weak amplitudes of diffractions make them… read more here.
