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…
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 instantaneous radial growth rate of stellar discs
Gabriele Pezzulli, Filippo Fraternali, Samuel Boissier +1
We present a new and simple method to measure the instantaneous mass and radial growth rates of the stellar discs of spiral galaxies, based on their star formation rate surface den…
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…
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…
The GALEX/S4G UV-IR color-color diagram: Catching spiral galaxies away from the Blue Sequence
Alexandre Y. K. Bouquin, Armando Gil de Paz, Samuel Boissier +8
We obtained GALEX FUV, NUV, and Spitzer/IRAC 3.6m photometry for > 2000 galaxies, available for 90% of the S4G sample. We find a very tight "GALEX Blue Sequence (GBS)" in the (F…
