The Carnegie-Irvine Galaxy Survey. II. Isophotal Analysis
Zhao-Yu Li, Luis C. Ho, Aaron J. Barth +1
The Carnegie-Irvine Galaxy Survey (CGS) is a comprehensive investigation of the physical properties of a complete, representative sample of 605 bright (B_T <= 12.9 mag) galaxies in…
The Carnegie-Irvine Galaxy Survey. I. Overview and Atlas of Optical Images
Luis C. Ho, Zhao-Yu Li, Aaron J. Barth +2
The Carnegie-Irvine Galaxy Survey (CGS) is a long-term program to investigate the photometric and spectroscopic properties of a statistically complete sample of 605 bright (B_T < 1…
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…
The impact of galaxy interactions on AGN activity in zCOSMOS
J. D. Silverman, P. Kampczyk, K. Jahnke +52
Close encounters between galaxies are expected to be a viable mechanism, as predicted by numerical simulations, by which accretion onto supermassive black holes can be initiated. T…
Cosmological evolution of supermassive black holes. I. mass function at 0<z<2
Yan-Rong Li, Luis C. Ho, Jian-Min Wang
We present the mass function of supermassive black holes (SMBHs) over the redshift range z=0-2, using the latest deep luminosity and mass functions of field galaxies to constrain t…
Thick disks of edge-on galaxies seen through the Spitzer Survey of Stellar Structure in Galaxies (S4G): Lair of missing baryons?
Sébastien Comerón, Bruce G. Elmegreen, Johan H. Knapen +21
Most, if not all, disk galaxies have a thin (classical) disk and a thick disk. In most models thick disks are thought to be a necessary consequence of the disk formation and/or evo…
