Mergers in Galaxy Groups. II. The Fundamental Plane of Elliptical Galaxies

Published in Monthly Notices of the Royal Astronomical Society, 2015

This second paper from my PhD thesis concluded that Paper I’s simulations follow a similar fundamental plane relation to observed ellipticals, but with a shallower slope, implying that some dissipation is likely necessary to form realistic ellipticals.

Quenching star formation in cluster galaxies

Published in Monthly Notices of the Royal Astronomical Society, 2014

This undergraduate thesis paper presented simplified models for the evolution of star formation in galaxies in rich clusters. Comparioson of model predictions to observations showed that typical galaxies are quenched on longer exponential time-scales of 3-3.5 Gyr, whereas models with very rapid quenching (<1Gyr) are disfavoured as they produce excessively old and red galaxies.

Mergers in Galaxy Groups. I. Structure and Properties of Elliptical Remnants

Published in The Astrophysical Journal, 2013

This first paper from my PhD thesis presented novel N-body simulations of mergers of spiral galaxies in groups of three to twenty-five. Analysis of synthetic images and kinematic maps showed that the merger remnants formed in the centers of these groups have very similar properties to nearby elliptical galaxies, showing that multiple, gas-poor and sometimes minor mergers are an alternative formation mechanism to the previously favoured paradigm of a single gas-rich major merger.
