Testing galaxy formation models with the GHOSTS survey: The color profile of M81's stellar halo
Antonela Monachesi, Eric F. Bell, David Radburn-Smith +6
We study the properties of the stellar populations in M81's outermost part, which hereafter we will term the stellar halo, using HST ACS/WFC observations of 19 fields from the GHOS…
Outer-Disk Populations in NGC 7793: Evidence for Stellar Radial Migration
David J. Radburn-Smith, Rok Roskar, Victor P. Debattista +8
We analyzed the radial surface brightness profile of the spiral galaxy NGC 7793 using HST/ACS images from the GHOSTS survey and a new HST/WFC3 image across the disk break. We used…
Outer Spiral Disks as Clues to Galaxy Formation and Evolution
Marija Vlajić
Recent studies of outer spiral disks have given rise to an abundance of new results. We discuss the observational and theoretical advances that have spurred the interest in disk ou…
The Abundance Gradient in the Extremely Faint Outer Disk of NGC 300
Marija Vlajić, Joss Bland-Hawthorn, Ken C. Freeman
In earlier work, we showed for the first time that the resolved stellar disk of NGC 300 is very extended with no evidence for truncation, a phenomenon that has since been observed…
