AGN Host Galaxy Morphologies in COSMOS
J. M. Gabor, C. D. Impey, K. Jahnke +14
We use HST/ACS images and a photometric catalog of the COSMOS field to analyze morphologies of the host galaxies of approximately 400 AGN candidates at redshifts 0.3 < z < 1.0. We…
Relation Between Stellar Mass and Star Formation Activity in Galaxies
Bahram Mobasher, T. Dahlen, A. Hopkins +8
For a mass-selected sample of 66544 galaxies with photometric redshifts from the Cosmic Evolution Survey (COSMOS), we examine the evolution of star formation activity as a function…
Color, 3D simulated images with shapelets
M. Ferry, J. Rhodes, R. Massey +3
We present a method to simulate color, 3-dimensional images taken with a space-based observatory by building off of the established shapelets pipeline. The simulated galaxies exhib…
The Phoenix Deep Survey: Extremely Red Galaxies and Cluster Candidates
Anthony G. Smith, Andrew M. Hopkins, Richard W. Hunstead +6
We present the results of a study of a sample of 375 Extremely Red Galaxies (ERGs) in the Phoenix Deep Survey, 273 of which constitute a subsample which is 80% complete to K_s = 18…
The HST/ACS Coma Cluster Survey: I - Survey Objectives and Design
David Carter, Paul Goudfrooij, Bahram Mobasher +34
We describe the HST ACS Coma cluster Treasury survey, a deep two-passband imaging survey of one of the nearest rich clusters of galaxies, the Coma cluster (Abell 1656). The survey…
SuperNova Acceleration Probe (SNAP): Investigating Photometric Redshift Optimization
Tomas Dahlen, Bahram Mobasher, Stephanie Jouvel +5
The aim of this paper is to investigate ways to optimize the accuracy of photometric redshifts for a SNAP like mission. We focus on how the accuracy of the photometric redshifts de…
