The Atacama Cosmology Telescope: Physical Properties of Sunyaev-Zel'dovich Effect Clusters on the Celestial Equator
Felipe Menanteau, Cristóbal Sifón, L. Felipe Barrientos +28
We present the optical and X-ray properties of 68 galaxy clusters selected via the Sunyaev-Zel'dovich Effect at 148 GHz by the Atacama Cosmology Telescope (ACT). Our sample, from a…
The Atacama Cosmology Telescope: Data Characterization and Map Making
Rolando Dünner, Matthew Hasselfield, Tobias A. Marriage +71
We present a description of the data reduction and mapmaking pipeline used for the 2008 observing season of the Atacama Cosmology Telescope (ACT). The data presented here at 148 GH…
The QUIET Instrument
QUIET Collaboration, C. Bischoff, A. Brizius +52
The Q/U Imaging ExperimenT (QUIET) is designed to measure polarization in the Cosmic Microwave Background, targeting the imprint of inflationary gravitational waves at large angula…
The Atacama Cosmology Telescope: Cross-Correlation of CMB Lensing and Quasars
Blake D. Sherwin, Sudeep Das, Amir Hajian +28
We measure the cross-correlation of Atacama Cosmology Telescope CMB lensing convergence maps with quasar maps made from the Sloan Digital Sky Survey DR8 SDSS-XDQSO photometric cata…
The Atacama Cosmology Telescope: Relation Between Galaxy Cluster Optical Richness and Sunyaev-Zel'dovich Effect
Neelima Sehgal, Graeme Addison, Nick Battaglia +33
We present the measured Sunyaev-Zel'dovich (SZ) flux from 474 optically-selected MaxBCG clusters that fall within the Atacama Cosmology Telescope (ACT) Equatorial survey region. Th…
The Atacama Cosmology Telescope: A Measurement of the Thermal Sunyaev-Zel'dovich Effect Using the Skewness of the CMB Temperature Distribution
Michael J. Wilson, Blake D. Sherwin, J. Colin Hill +35
We present a detection of the unnormalized skewness <T^3> induced by the thermal Sunyaev-Zel'dovich (tSZ) effect in filtered Atacama Cosmology Telescope (ACT) 148 GHz cosmic microw…
