Unveiling the Structure of Barred Galaxies at 3.6 with the Spitzer Survey of Stellar Structure in Galaxies (SG): I. Disk Breaks
Taehyun Kim, Dimitri A. Gadotti, Kartik Sheth +24
We have performed two-dimensional multicomponent decomposition of 144 local barred spiral galaxies using 3.6 images from the Spitzer Survey of Stellar Structure in Galax…
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
Star-forming regions that are visible at 3.6 microns and Halpha but not in the u,g,r,i,z bands of the Sloan Digital Sky survey (SDSS), are measured in five nearby spiral galaxies t…
Morphological Parameters of Spitzer Survey of Stellar Structure in Galaxies (S4G)
B. W. Holwerda, J-C. Munoz-Mateos, S. Comeron +21
The morphology of galaxies can be quantified to some degree using a set of scale-invariant parameters. Concentration (C), Asymmetry (A), Smoothness (S), the Gini index (G), relativ…
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…
Inner rings in disc galaxies: dead or alive
Sébastien Comerón
In this Letter, I distinguish "passive" inner rings as those with no current star formation, as distinct from "active" inner rings that have undergone recent star formation. I buil…
