An Evolutionary Model For Submillimeter Galaxies
Sukanya Chakrabarti, Yeshe Fenner, Lars Hernquist +2
[abridged]We calculate multi-wavelength spectral energy distributions (SEDs) (spanning optical to millimeter wavelengths) from simulations of major galaxy mergers with black hole f…
The Chemical Evolution of Helium in Globular Clusters: Implications for the Self-Pollution Scenario
Amanda Karakas, Yeshe Fenner, Alison Sills +2
We investigate the suggestion that there are stellar populations in some globular clusters with enhanced helium (Y from 0.28 to 0.40) compared to the primordial value. We assume th…
Helium enhancements in globular cluster stars from Asymptotic Giant Branch star pollution
Amanda Karakas, Yeshe Fenner, Alison Sills +2
Using a chemical evolution model we investigate the intriguing suggestion that there are populations of stars in some globular clusters (e.g. NGC 2808, omega Centauri) with enhance…
Cosmological implications of dwarf spheroidal chemical evolution
Yeshe Fenner, Brad K. Gibson, Roberto Gallino +1
The chemical properties of dwarf spheroidals in the local group are shown to be inconsistent with star formation being truncated after the reionization epoch (z~8). Enhanced levels…
Abundance Anomalies in NGC6752 - Do AGB Stars Have a Role?
S. W. Campbell, Y. Fenner, A. I. Karakas +2
We are in the process of testing a popular theory that the observed abundance anomalies in the Globular Cluster NGC 6752 are due to `internal pollution' from intermediate mass asym…
Galactic Chemical Evolution Redux: Atomic Numbers 6 < Z < 15
B. K. Gibson, Y. Fenner, A. Kiessling
Motivated by the inability of Galactic chemical evolution models to reproduce some of the observed solar neighbourhood distribution of elements (and isotopes) with atomic numbers 6…
