Current research project

Supernovae: Theoretical Modelling of Light Curves and Spectra

 

Type Ia supernovae are complex and powerful astrophysical phenomena. They are highly relevant to many astrophysics disciplines such as stellar evolution, nucleosynthesis, and cosmology. Computational modelling of radiative transfer allows for the development of understanding between the underlying physical conditions and the observables.

My research involves the use of the radiative transfer code ARTIS (Applied Radiative Transfer In Supernovae) to computationally model Type Ia Supernovae, primarily spectra and light curves, as well as other properties. Currently, the focus of my research is on the investigation of the potential double-degenerate double-detonation Type Ia evolutionary pathway. One of the aims of this research is to help further the understanding of underlying progenitor systems which are involved in Type Ia Supernovae.

Biography

I started my PhD at the Astrophysics Research Centre in October 2022 after completing my Master's degree in Physics at Queens University Belfast. My Master's research project was also conducted with Dr Stuart Sim, this project involved the modelling of a Type Ia Supernovae using a radiative transfer code TARDIS (Temperature And Radiative Diffusion In Supernovae); this led me to apply for a PhD in the Supernova research group at Queen's.
