ALMA Imaging of HCN, CS and dust in Arp 220 and NGC 6240
Nick Scoville, Kartik Sheth, Fabian Walter +19
We report ALMA Band 7 (350 GHz) imaging at 0.4 - 0.6arcsec resolution and Band 9 (696 GHz) at ~0.25arcsec resolution of the luminous IR galaxies Arp 220 and NGC 6240. The long wave…
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,…
Confirming the Quiescent Galaxy Population out to : A Stacking Analysis of Mid-, Far-Infrared and Radio Data
Allison W. S. Man, Thomas R. Greve, Sune Toft +15
We present stringent constraints on the average mid-, far-infrared and radio emissions of 14200 quiescent galaxies (QGs), identified out to in the COSMOS field via thei…
ALMA Observations of the Antennae Galaxies: I. A New Window on a Prototypical Merger
Bradley C. Whitmore, Crystal Brogan, Rupali Chandar +7
We present the highest spatial resolution (~0.5") CO (3-2) observations to date of the "overlap" region in the merging Antennae galaxies (NGC 4038/39), taken with the ALMA. We repo…
Multi-molecule ALMA observations towards the Seyfert 1 galaxy NGC 1097
S. Martin, K. Kohno, T. Izumi +17
The nearby Sy 1 galaxy NGC 1097 represents an ideal laboratory to explore the molecular chemistry in the presence and surroundings of an active galactic nucleus. Exploring the dist…
Evolution of the specific Star Formation Rate Function at z<1.4 - Dissecting the mass-SFR plane in COSMOS and GOODS
O. Ilbert, S. Arnouts, E. Le Floc'h +21
The relation between the stellar mass and the star formation rate characterizes how the instantaneous star formation is determined by the galaxy past star formation history and by…
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…
The role of bars in AGN fueling in disk galaxies over the last seven billion years
Mauricio Cisternas, Kartik Sheth, Mara Salvato +3
We present empirical constraints on the influence of stellar bars on the fueling of active galactic nuclei (AGNs) out to z=0.84 using a sample of X-ray-selected AGNs hosted in lumi…
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…
Star Formation at From the Spitzer Large Area Survey with Hyper-Suprime-Cam (SPLASH)
Charles L. Steinhardt, Josh S. Speagle, Peter Capak +21
Using the first 50% of data collected for the Spitzer Large Area Survey with Hyper-Suprime-Cam (SPLASH) observations on the 1.8 deg Cosmological Evolution Survey (COSMOS) we es…
Late-stage galaxy mergers in COSMOS to z~1
C. N. Lackner, J. D. Silverman, M. Salvato +14
The role of major mergers in galaxy and black hole formation is not well constrained. To help address this, we develop an automated method to identify late-stage galaxy mergers bef…
The zCOSMOS Redshift Survey: evolution of the light in bulges and discs since z~0.8
L. A. M. Tasca, L. Tresse, O. Le Fevre +52
We studied the chronology of galactic bulge and disc formation by analysing the relative contributions of these components to the B-band rest-frame luminosity density at different…
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…
The Evolution of ISM Mass Probed by Dust Emission -- ALMA Observations at z = 0.3 to 2
N. Scoville, H. Aussel, K. Sheth +9
The use of submm dust continuum emission to probe the mass of interstellar dust and gas in galaxies is empirically calibrated using samples of local star forming galaxies, Planck o…
Sub-millimeter galaxies as progenitors of compact quiescent galaxies
S. Toft, V. Smolcic, B. Magnelli +16
Three billion years after the big bang (at redshift z=2), half of the most massive galaxies were already old, quiescent systems with little to no residual star formation and extrem…
