APOGEE Kinematics I: Overview of the Kinematics of the Galactic Bulge as Mapped by APOGEE
M. Ness, G. Zasowski, J. A. Johnson +12
We present the stellar kinematics across the Galactic bulge and into the disk at positive longitudes from the SDSS-III APOGEE spectroscopic survey of the Milky Way. APOGEE includes…
Globular Cluster Populations: Results Including SG Late-Type Galaxies
Dennis Zaritsky, Kelsey McCabe, Manuel Aravena +18
Using 3.6 and 4.5m images of 73 late-type, edge-on galaxies from the SG survey, we compare the richness of the globular cluster populations of these galaxies to those of ear…
Spectral analysis of stellar orbits in a tidally induced bar
Grzegorz Gajda, Ewa L. Lokas, E. Athanassoula
Using numerical analysis of fundamental frequencies we study the orbital structure of a tidally induced bar formed in a simulated dwarf galaxy orbiting a Milky Way-like host. We fi…
Environmental regulation of cloud and star formation in galactic bars
F. Renaud, F. Bournaud, E. Emsellem +7
The strong time-dependence of the dynamics of galactic bars yields a complex and rapidly evolving distribution of dense gas and star forming regions. Although bars mainly host regi…
The Odd Offset between the Galactic Disk and Its Bar in NGC 3906
Bonita de Swardt, Kartik Sheth, Taehyun Kim +27
We use mid-infrared 3.6 and 4.5microns imaging of NGC 3906 from the Spitzer Survey of Stellar Structure in Galaxies (S4G) to understand the nature of an unusual offset between its…
The Spitzer Survey of Stellar Structure in Galaxies (S4G): Stellar Masses, Sizes and Radial Profiles for 2352 Nearby Galaxies
Juan Carlos Munoz-Mateos, Kartik Sheth, Michael Regan +25
The Spitzer Survey of Stellar Structure in Galaxies (S4G) is a volume, magnitude, and size-limited survey of 2352 nearby galaxies with deep imaging at 3.6 and 4.5um. In this paper…
Stellar Populations of Barred Quiescent Galaxies
Edmond Cheung, Charlie Conroy, E. Athanassoula +10
Selecting centrally quiescent galaxies from the Sloan Digital Sky Survey (SDSS) to create high signal-to-noise (>100) stacked spectra with minimal emission line contamination, we a…
H-alpha kinematics of S4G spiral galaxies-II. Data description and non-circular motions
Santiago Erroz-Ferrer, Johan H. Knapen, Ryan Leaman +15
We present a kinematical study of 29 spiral galaxies included in the Spitzer Survey of Stellar Structure in Galaxies, using Halpha Fabry-Perot data obtained with the Galaxy Halpha…
2D kinematic signatures of boxy/peanut bulges
Francesca Iannuzzi, E. Athanassoula
We study the imprints of boxy/peanut structures on the 2D line-of-sight kinematics of simulated disk galaxies. The models under study belong to a family with varying initial gas fr…
Boxy/peanut/X bulges, barlenses and the thick part of galactic bars: What are they and how did they form?
E. Athanassoula
Bars have a complex three-dimensional shape. In particular their inner part is vertically much thicker than the parts further out. Viewed edge-on, the thick part of the bar is what…
The Effects of Boxy/Peanut Bulges on Galaxy Models
F. Fragkoudi, E. Athanassoula, A. Bosma +1
We examine the effects that the modelling of a Boxy/Peanut (B/P) bulge will have on the estimates of the stellar gravitational potential, forces, orbital structure and bar strength…
A Classical Morphological Analysis of Galaxies in the Spitzer Survey of Stellar Structure in Galaxies (S4G)
R. Buta, K. Sheth, E. Athanassoula +22
The Spitzer Survey of Stellar Structure in Galaxies (S4G) is the largest available database of deep, homogeneous middle-infrared (mid-IR) images of galaxies of all types. The surve…
