The Stellar Halo Metallicity - Luminosity Relationship for Spiral Galaxies
Agostino Renda, Brad K. Gibson, Mustapha Mouhcine +4
The stellar halos of spiral galaxies bear important chemo-dynamical signatures of galaxy formation. We present here the analysis of 89 semi-cosmological spiral galaxy simulations,…
On the origin of fluorine in the Milky Way
A. Renda, Y. Fenner, B. K. Gibson +6
The main astrophysical factories of fluorine (19F) are thought to be Type II supernovae, Wolf-Rayet stars, and the asymptotic giant branch (AGB) of intermediate mass stars. We pres…
Contrasting the chemical evolution of the Milky Way and Andromeda galaxies
Agostino Renda, Daisuke Kawata, Yeshe Fenner +1
The chemical evolution history of a galaxy hides clues about how it formed and has been changing through time. We have studied the chemical evolution history of the Milky Way (MW)…
Photometric Properties of White Dwarf Dominated Halos
H. -c. Lee, B. K. Gibson, Y. Fenner +5
Using stellar population synthesis techniques, we explore the photometric signatures of white dwarf progenitor dominated galactic halos, in order to constrain the fraction of halo…
Galactic Chemical Evolution
Brad K. Gibson, Yeshe Fenner, Agostino Renda +2
The primary present-day observables upon which theories of galaxy evolution are based are a system's morphology, dynamics, colour, and chemistry. Individually, each provides an imp…
Modelling the nova rate in galaxies
Francesca Matteucci, Agostino Renda, Antonio Pipino +1
We compute theoretical nova rates as well as type Ia SN rates in galaxies of different morphological type (Milky Way, ellipticals and irregulars) by means of detailed chemical evol…
