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…

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…

ARRAKIS: Atlas of Resonance Rings As Known In the S4G
S. Comerón, H. Salo, E. Laurikainen +19
Resonance rings are the consequence of secular evolution processes that redistribute material and angular momentum in discs. We produced a Catalogue and an Atlas of the rings detec…
Embedded Star Formation in S4G Galaxy Dust Lanes
Debra M. Elmegreen, Bruce G. Elmegreen, Santiago Erroz-Ferrer +22

X-ray nuclear activity in S4G barred galaxies: No link between bar strength and co-occurrent supermassive black hole fueling
Mauricio Cisternas, Dimitri Gadotti, Johan H. Knapen +23
Stellar bars can lead to gas inflow toward the center of a galaxy and stimulate nuclear star formation. However, there is no compelling evidence on whether they also feed a central…
