Optimal filter systems for photometric redshift estimation
N. Benitez, M. Moles, J. A. L. Aguerri +18
In the next years, several cosmological surveys will rely on imaging data to estimate the redshift of galaxies, using traditional filter systems with 4-5 optical broad bands; narro…
VLT and ACS observations of RDCS J1252.9-2927: dynamical structure and galaxy populations in a massive cluster at z=1.237
R. Demarco, P. Rosati, C. Lidman +26
We present results from an extensive spectroscopic survey, carried out with VLT FORS, and from an extensive multiwavelength imaging data set from the HST Advanced Camera for Survey…
Lyman break galaxies, Lya emitters and a radio galaxy in a protocluster at z=4.1
Roderik A. Overzier, R. J. Bouwens, N. J. G. Cross +17
We present deep HST/ACS observations in g,r,i,z towards the z=4.1 radio galaxy TN J1338-1942 and its overdensity of >30 spectroscopically confirmed Lya emitters (LAEs). We select 6…
The Morphological Demographics of galaxies in the ACS Hubble Ultra Deep Parallel Fields
Felipe Menanteau, Holland C. Ford, Veronica Motta +4
We present a morphological analysis of distant field galaxies using the deep ACS images from the public parallel NICMOS observations of the Hubble Ultra Deep Field obtained in the…
Clustering of Star-forming Galaxies Near a Radio Galaxy at z=5.2
Roderik A. Overzier, G. K. Miley, R. J. Bouwens +13
We present HST/ACS observations of the most distant radio galaxy known, TN J0924-2201 at z=5.2. This radio galaxy has 6 spectroscopically confirmed Lya emitting companion galaxies,…
Feedback and Brightest Cluster Galaxy Formation: ACS Observations of the Radio Galaxy TN J1338--1942 at z=4.1
Andrew W. Zirm, R. A. Overzier, G. K. Miley +12
We present deep optical imaging of the z=4.1 radio galaxy TN J1338--1942 obtained using the ACS on-board HST. The radio galaxy is known to reside within a large galaxy overdensity…
Evolution in the Cluster Early-type Galaxy Size-Surface Brightness Relation at z =~ 1
B. P. Holden, J. P. Blakeslee, M. Postman +7
We investigate the evolution in the distribution of surface brightness, as a function of size, for elliptical and S0 galaxies in the two clusters RDCS J1252.9-2927, z=1.237 and RX…
A VLT spectroscopic survey of RX J0152.7-1357, a forming cluster of galaxies at z=0.837
R. Demarco, P. Rosati, C. Lidman +12
We present the results of an extensive spectroscopic survey of RX J0152.7-1357, one of the most massive distant clusters of galaxies known. Multi-object spectroscopy, carried out w…
Weak Lensing Analysis of the z~0.8 cluster CL 0152-1357 with the Advanced Camera for Surveys
M. J. Jee, R. L. White, N. Benitez +5
We present a weak lensing analysis of the X-ray luminous cluster CL 0152-1357 at z~0.84 using HST/ACS observations. The unparalleled resolution and sensitivity of ACS enable us to…
Photometric Redshifts for Galaxies in the GOODS Southern Field
B. Mobasher, R. Idzi, N. Benitez +28
We use extensive multi-wavelength photometric data from the Great Observatories Origins Deep Survey (GOODS) to estimate photometric redshifts for a sample of 434 galaxies with spec…
Advanced Camera for Surveys Photometry of the Cluster RDCS1252.9-2927: The Color-Magnitude Relation at z=1.24
J. P. Blakeslee, M. Franx, M. Postman +20
We investigate the color-magnitude (CM) relation of galaxies in the distant X-ray selected cluster RDCS1252.9-2927 at z=1.24 using images obtained with the Advanced Camera for Surv…
Gravitational Lens Magnification and the Mass of Abell 1689
A. N. Taylor, S. Dye, T. J. Broadhurst +2
We present the first application of lens magnification to measure the absolute mass of a galaxy cluster; Abell 1689. The absolute mass of a galaxy cluster can be measured by the gr…
