The Infall of Gas onto the Galactic Disk
Brad K. Gibson
Ongoing accretion of low-metallicity gas onto the disk is a natural prediction of semi-analytical Galactic chemical evolution models. This star formation fuel ameliorates the overp…
Simulating a white dwarf dominated halo
C. B. Brook, Daisuke Kawata, Brad K. Gibson
Halo initial mass functions (IMFs) heavily biased toward white dwarf (WD) precursors ~1-8 Msun have been suggested as a suitable mechanism for explaining MACHO events. However, by…
A Numerical Study of the Chemo-Dynamical Evolution of Elliptical Galaxies
Daisuke Kawata, Brad K. Gibson
We investigate the chemo-dynamical evolution of elliptical galaxies, to understand the origin of the mass-dependence of photometric properties such as the colour-magnitude relation…
Are High-Velocity Clouds the Building Blocks of the Local Group?
Brad K. Gibson, Yeshe Fenner, Sarah T. Maddison +1
Motivated by the apparent order-of-magnitude discrepancy between the observed number of Local Group satellite galaxies, and that predicted by Lambda-CDM hierarchical clustering cos…
