The low-mass IMF - deep star counts in the dSph galaxy Ursa Minor
Sofia Feltzing, Rosemary Wyse, Mark Houdashelt +1
We present a new study of deep star counts in the Local Group dwarf spheroidal (dSph) in Ursa Minor. Both the luminosity function (LF) and the colour-magnitude diagram (CMD) of the…
The Low-Mass Stellar IMF at High Redshift: Faint Stars in the Ursa Minor Dwarf Spheroidal Galaxy
Rosemary F. G. Wyse, Gerard Gilmore, Sofia Feltzing +1
Low-mass stars, those with main-sequence lifetimes that are of order the age of the Universe, provide unique constraints on the Initial Mass Function (IMF) when they formed. Star c…
Optical Synthetic Spectra of Elliptical Galaxies
R. A. Bell, M. L. Houdashelt
We present the first results from our population synthesis models of elliptical galaxies. In this paper, we concentrate upon the optical region of the spectrum (3000-7000 A). We mo…
Near-Infrared Synthetic Spectra of Elliptical Galaxies
M. L. Houdashelt, R. A. Bell
We present the first results from our population synthesis models of elliptical galaxies. In this paper, we concentrate upon the near-infrared region of the spectrum (0.7-3 um). We…
