BUBBLY: A method for detecting and characterizing interstellar bubbles using Fabry-Perot spectroscopy
Artemi Camps-Fariña, Javier Zaragoza-Cardiel, John E. Beckman +4
We present a new method for the detection and characterization of expansion in galaxy discs based on Hα Fabry-Perot spectroscopy, taking advantage of the high spatial and velocity…
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…
Two physical regimes for the Giant HII Regions and Giant Molecular Clouds in the Antennae Galaxies
Javier Zaragoza-Cardiel, Joan Font, John E. Beckman +3
We have combined observations of the Antennae galaxies from the radio interferometer ALMA (Atacama Large Millimeter/submillimeter Array) and from the optical interferometer GHFa…
IRAC Near-Infrared Features in the Outer Parts of S4G Galaxies
Seppo Laine, Johan H. Knapen, Juan-Carlos Munoz-Mateos +26
We present a catalogue and images of visually detected features, such as asymmetries, extensions, warps, shells, tidal tails, polar rings, and obvious signs of mergers or interacti…
Optical imaging for the Spitzer Survey of Stellar Structure in Galaxies. Data release and notes on interacting galaxies
Johan H. Knapen, Santiago Erroz-Ferrer, Javier Roa +4
(Abridged) The Spitzer Survey for Stellar Structure in Galaxies (S4G) and its more recently approved extension will lead to a set of 3.6 and 4.5 micron images for 2829 galaxies, wh…
Morphology and environment of galaxies with disc breaks in the S4G and NIRS0S
J. Laine, E. Laurikainen, H. Salo +16
We study the surface brightness profiles of disc galaxies in the 3.6 micron images from the Spitzer Survey of Stellar Structure in Galaxies (S4G) and K_s-band images from the Near…
The Baryonic Tully-Fisher Relationship for SG Galaxies and the "Condensed" Baryon Fraction of Galaxies
Dennis Zaritsky, Helene Courtois, Juan-Carlos Muñoz-Mateos +20
We combine data from the Spitzer Survey for Stellar Structure in Galaxies (SG), a recently calibrated empirical stellar mass estimator from Eskew et al., and an extensive datab…
Reconstructing the stellar mass distributions of galaxies using S4G IRAC 3.6 and 4.5 micron images: II. The conversion from light to mass
Sharon E. Meidt, Eva Schinnerer, Glenn van de Ven +26
We present a new approach for estimating the 3.6 micron stellar mass-to-light ratio in terms of the [3.6]-[4.5] colors of old stellar populations. Our approach avoids several of th…
