Spitzer UltRa Faint SUrvey Program (SURFS UP). II. IRAC-Detected Lyman-Break Galaxies at 6 < z < 10 Behind Strong-Lensing Clusters
Kuang-Han Huang, Maruša Bradač, Brian C. Lemaux +15
We study the stellar population properties of the IRAC-detected galaxy candidates from the Spitzer UltRa Faint SUrvey Program (SURFS UP). Using the Lyman…
Reconstruction of small-scale galaxy cluster substructure with lensing flexion
Benjamin Cain, Marusa Bradac, Rebecca Levinson
We present a reconstructions of galaxy-cluster-scale mass distributions from simulated gravitational lensing data sets including strong lensing, weak lensing shear, and measurement…
RCS2 J232727.6-020437: An Efficient Cosmic Telescope at
Austin Hoag, Maruša Bradač, Kuang-Han Huang +13
We present a detailed gravitational lens model of the galaxy cluster RCS2 J232727.6-020437. Due to cosmological dimming of cluster members and ICL, its high redshift () m…
Measuring the Stellar Masses of z~7 Galaxies with Spitzer Ultrafaint Survey Program (SURFS UP)
R. E. Ryan, A. H. Gonzalez B. C. Lemaux, M. Bradac +14
We present Spitzer/IRAC observations of nine -band dropouts highly magnified (2<mu<12) by the Bullet Cluster. We combine archival imaging with our Exploratory program (SURFS UP…
Spitzer UltRa Faint SUrvey Program (SURFS UP) I: An Overview
Maruša Bradač, Russell Ryan, Stefano Casertano +14
SURFSUP is a joint Spitzer and HST Exploration Science program using 10 galaxy clusters as cosmic telescopes to study z >~ 7 galaxies at intrinsically lower luminosities, enabled b…
Measuring Gravitational Lensing Flexions in Abell 1689 Using an Analytic Image Model
Benjamin Cain, Paul L. Schechter, M. W. Bautz
Measuring dark matter substructure within galaxy cluster haloes is a fundamental probe of the Lambda-CDM model of structure formation. Gravitational lensing is a technique for meas…
Chandra X-ray Observations of the 0.6 < z < 1.1 Red-Sequence Cluster Survey Sample
Amalia K. Hicks, Erica Ellingson, Mark Bautz +6
We present the results of Chandra observations of 13 optically-selected clusters with 0.6<z< 1.1, discovered via the Red-sequence Cluster Survey (RCS). All but one are detected at…
Evidence for line-of-sight structure in a comparison of X-ray and optical observations of the high-redshift cluster RCS043938-2904.7
Benjamin Cain, David G. Gilbank, M. W. Bautz +6
We present new Chandra observations of a high redshift (z~1) galaxy cluster discovered in the Red-Sequence Cluster Survey (RCS): RCS043938-2904.7. X-ray luminosity measurements and…
