Cosmology with Photometrically-Classified Type Ia Supernovae from the SDSS-II Supernova Survey
Heather Campbell, Chris B. D'Andrea, Robert C. Nichol +25
We present the cosmological analysis of 752 photometrically-classified Type Ia Supernovae (SNe Ia) obtained from the full Sloan Digital Sky Survey II (SDSS-II) Supernova (SN) Surve…
BEAMS: separating the wheat from the chaff in supernova analysis
Martin Kunz, Renée Hlozek, Bruce A. Bassett +3
We introduce Bayesian Estimation Applied to Multiple Species (BEAMS), an algorithm designed to deal with parameter estimation when using contaminated data. We present the algorithm…
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 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…
Extending BEAMS to incorporate correlated systematic uncertainties
Michelle Lochner, Bruce A. Bassett, Melvin Varughese +4
New supernova surveys such as the Dark Energy Survey, Pan-STARRS and the LSST will produce an unprecedented number of photometric supernova candidates, most with no spectroscopic d…
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…
