Geometry of Star-Forming Galaxies from SDSS, 3D-HST and CANDELS
A. van der Wel, Yu-Yen Chang, E. F. Bell +18
We determine the intrinsic, 3-dimensional shape distribution of star-forming galaxies at 0<z<2.5, as inferred from their observed projected axis ratios. In the present-day universe…
Morphologies of z~0.7 AGN Host Galaxies in CANDELS: No trend of merger incidence with AGN luminosity
C. Villforth, F. Hamann, D. J. Rosario +24
The processes that trigger Active Galactic Nuclei (AGN) remain poorly understood. While lower luminosity AGN may be triggered by minor disturbances to the host galaxy, stronger dis…
New Image Statistics for Detecting Disturbed Galaxy Morphologies at High Redshift
P. E. Freeman, R. Izbicki, A. B. Lee +5
Testing theories of hierarchical structure formation requires estimating the distribution of galaxy morphologies and its change with redshift. One aspect of this investigation invo…
The host galaxies of X-ray selected Active Galactic Nuclei to z=2.5: Structure, star-formation and their relationships from CANDELS and Herschel/PACS
D. J. Rosario, D. H. McIntosh, A. van der Wel +60
We study the relationship between the structure and star-formation rate (SFR) of X-ray selected low and moderate luminosity active galactic nuclei (AGNs) in the two Chandra Deep Fi…
X-ray selected AGN Hosts are Similar to Inactive Galaxies out to z=3: Results from CANDELS/CDF-S
D. J. Rosario, M. Mozena, S. Wuyts +18
We use multi-band spatially resolved photometry from the Cosmic Assembly Near-IR Deep Legacy Survey (CANDELS) in the 4 MSec Chandra Deep Field-South (CDF-S) to explore the nuclear…
Structural Parameters of Galaxies in CANDELS
A. van der Wel, E. F. Bell, B. Haussler +19
We present global structural parameter measurements of 109,533 unique, H_F160W-selected objects from the CANDELS multi-cycle treasury program. Sersic model fits for these objects a…
