PhD Student | Galactic Dynamics

Jeremiah Horrocks Institute, UCLan

Welcome...

I am a PhD research student at the Jeremiah Horrocks Institute, University of Central Lancashire as part of the Galaxy Dynamics research group led by Prof. Victor P. Debattista. My primary research is studying the formation and evolution of box/peanut bulges in barred galaxies by comparing isolated and cosmological simulations to observations of external galaxies and the Milky Way.

My position is funded by the Moses Holden Studentship, dedicated to the Lancashire astronomer and educator. I am currently a Junior Associate of the LSST:UK Consortium as part of the Galaxies; Stars, Milky Way and Local Volume Science Collaboration and a member of the N-Body Shop. Part of my current research, Gough-Kelly et al. (2022), bridges these two memberships by making predictions for kinematic differences between populations within the Milky Way bulge.

I am also currently Vice Chair of the Royal Astronomical Society Early Career Network Steering Committee. Find out more about the network here.

Research

Galaxy dynamics helps us understand how galaxies form and evolve over time. My research focuses on the evolution of the central structures of disc galaxies, such as bars, nuclear discs, and bulges in galaxies similar to the Milky Way.

We are particularly interested in the slow internal processes that dominate large-scale changes over the billions of years following the initial turbulent formation period.

The chemical and spatial variations of the bulge's velocity ellipsoids

We study the velocity ellipsoids in an N-body$+$SPH (smooth particle hydrodynamics) simulation of a barred galaxy which forms a bar with a BP bulge. We focus on the 2D kinematics, …
