On the relation between metallicity and RGB color in HST/ACS data
David Streich, Roelof S. de Jong, Jeremy Bailin +3
The determination of stellar metallicity and its gradient in external galaxies is a difficult task, but crucial for the understanding of galaxy formation and evolution. The color o…
GHOSTS I: A New Faint very Isolated Dwarf Galaxy at D = 12 +/- 2 Mpc
Antonela Monachesi, Eric F. Bell, David J. Radburn-Smith +8
We report the discovery of a new faint dwarf galaxy, GHOSTS I, using HST/ACS data from one of our GHOSTS (Galaxy Halos, Outer disks, Substructure, Thick disk, and Star clusters) fi…
Evolution of Galactic Discs: Multiple Patterns, Radial Migration and Disc Outskirts
I. Minchev, B. Famaey, A. C. Quillen +5
We investigate the evolution of galactic disks in N-body Tree-SPH simulations. We find that disks, initially truncated at three scale-lengths, can triple their radial extent, solel…
The Structure and Metallicity Gradient in the Extreme Outer Disk of NGC 7793
Marija Vlajić, Joss Bland-Hawthorn, Kenneth C. Freeman
Studies of outer regions of spirals disks are fundamental to our understanding of both the process of galaxy assembly and the subsequent secular evolution of galaxies. In an earlie…
