Far-infrared Emission Lines as Metallicity Diagnostic

open access: yesThe Astrophysical Journal
The chemical abundance of the interstellar medium is a key tracer of galaxy evolution. Optical and ultraviolet emission lines are widely used to derive gas-phase metallicities, but suffer from uncertainties due to possible temperature fluctuations and ...

The effect of the environment on the evolution of galaxy colours [PDF]

open access: yes, 2006
In chapter 1 of this thesis, I give a brief overview of the birth of modern cosmology and the growth of the current paradigm. I then go on to describe the different types of galaxies, the star formation rates within them and give some notes about galaxy ...
