Nicholls, David Conway
The motive for this work was to investigate whether small, isolated gas-rich galaxies show
evidence of chemical evolution, by studying their nebular metallicities. I have identified
a sample of 83 objects chosen for low luminosity and mass, the presence of active star
formation, and isolation from other galaxies and galaxy clusters that might generate tidal
effects or enrich the intergalactic medium. From these I have measured the spectra of 35
objects, using theWiFeS IFU spectrograph on...[Show more]
