Evolution of the Milky Way with radial motions of stars and gas II. The evolution of abundance profiles from H to Ni
M. Kubryk, N. Prantzos, E. Athanassoula
We study the role of radial motions of stars and gas on the evolution of abundance profiles in the Milky Way disk. We investigate, in a parametrized way, the impact of radial flows…
The X-Shaped Milky Way Bulge in OGLE-III Photometry and in N-Body Models
David M. Nataf, Andrzej Udalski, Jan Skowron +11
We model the split red clump of the Galactic bulge in OGLE-III photometry, and compare the results to predictions from two N-body models. Our analysis yields precise maps of the br…
Evolution of the Milky Way with radial motions of stars and gas I. The solar neighborhood and the thin and thick disk
M. Kubryk, N. Prantzos, E. Athanassoula
We study the role of radial migration of stars on the chemical evolution of the Milky Way disk. In particular, we are interested in the impact of that process on the local properti…
The Mass Profile and Shape of Bars in the Spitzer Survey of Stellar Structure in Galaxies (S4G): Search for an Age Indicator for Bars
Taehyun Kim, Kartik Sheth, Dimitri A. Gadotti +24
We have measured the radial light profiles and global shapes of bars using two-dimensional 3.6 image decompositions for 144 face-on barred galaxies from the Spitzer Survey of…
Globular Cluster Populations: First Results from SG Early-Type Galaxies
Dennis Zaritsky, Manuel Aravena, E. Athanassoula +14
Using 3.6m images of 97 early-type galaxies, we develop and verify methodology to measure globular cluster populations from the SG survey images. We find that 1) the ratio,…
The Spitzer Survey of Stellar Structure in Galaxies (SG): Precise Stellar Mass Distributions from Automated Dust Correction at 3.6 microns
M. Querejeta, S. E. Meidt, E. Schinnerer +26
The mid-infrared is an optimal window to trace stellar mass in nearby galaxies and the 3.6 IRAC band has been exploited to this effect, but such mass estimates can be biased by…
