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…
On the Origin of Lopsidedness in Galaxies as Determined from the Spitzer Survey of Stellar Structure in Galaxies (S4G)
Dennis Zaritsky, Heikki Salo, Eija Laurikainen +23
We study the m=1 distortions (lopsidedness) in the stellar components of 167 nearby galaxies that span a wide range of morphologies and luminosities. We confirm the previous findin…
The impact of bars on disk breaks as probed by S4G imaging
J. C. Muñoz-Mateos, K. Sheth, A. Gil de Paz +25
We have analyzed the radial distribution of old stars in a sample of 218 nearby face-on disks, using deep 3.6um images from the Spitzer Survey of Stellar Structure in Galaxies (S4G…
Energetic galaxy-wide outflows in high-redshift ultra-luminous infrared galaxies hosting AGN activity
C. M. Harrison, D. M. Alexander, A. M. Swinbank +10
We present integral field spectroscopy observations, covering the [O III]4959,5007 emission-line doublet of eight high-redshift (z=1.4-3.4) ultra-luminous infrared galaxies (ULIRGs…
The S4G perspective on circumstellar dust extinction of AGB stars in M100
Sharon E. Meidt, Eva Schinnerer, Juan-Carlos Munoz-Mateos +19
We examine the effect of circumstellar dust extinction on the near-IR contribution of asymptotic giant branch (AGB) stars in intermediate-age clusters throughout the disk of M100.…
Reconstructing the stellar mass distributions of galaxies using S4G IRAC 3.6 and 4.5 micron images: I. Correcting for contamination by PAH, hot dust, and intermediate age stars
Sharon E. Meidt, Eva Schinnerer, Johan H. Knapen +23
With the aim of constructing accurate 2D maps of the stellar mass distribution in nearby galaxies from S4G 3.6 and 4.5 micron images, we report on the separation of the light from…
Extreme Starbursts in the Local Universe
R. M. Gonzalez Delgado, J. Rodriguez Zaurin, E. Perez +44
The "Extreme starbursts in the local universe" workshop was held at the Insituto de Astrofisica de Andalucia in Granada, Spain on 21-25 June 2010. Bearing in mind the advent of a n…
Mid-Infrared Galaxy Morphology from the Spitzer Survey of Stellar Structure in Galaxies (S^4G): The Imprint of the de Vaucouleurs Revised Hubble-Sandage Classification System at 3.6 microns
R. Buta, K. Sheth, M. Regan +17
Spitzer Space Telescope Infrared Array Camera (IRAC) imaging provides an opportunity to study all known morphological types of galaxies in the mid-IR at a depth significantly bette…
Starburst or AGN Dominance in Submillimetre-Luminous Candidate AGN?
Kristen Coppin, Alexandra Pope, Karin Menendez-Delmestre +2
It is widely believed that ultraluminous infrared (IR) galaxies and active galactic nuclei (AGN) activity are triggered by galaxy interactions and merging, with the peak of activit…
Spectroscopy of luminous z>7 galaxy candidates and sources of contamination in z>7 galaxy searches
P. Capak, B. Mobasher, N. Z. Scoville +22
We present three bright z+ dropout candidates selected from deep Near-Infrared (NIR) imaging of the COSMOS 2 square degree field. All three objects match the 0.8-8um colors of othe…
