Kavli Affiliate: Geza Gyuk | First 5 Authors: Geza Gyuk, Arlin Crotts, , , | Summary: We provide a set of microlensing optical depth maps for M31. Optical depths towards Andromeda were calculated on the basis of a four component model of the lens and source populations: disk and bulge sources lensed by bulge, M31 […]

Kavli Affiliate: John E. Carlstrom | First 5 Authors: Gilbert P. Holder, John E. Carlstrom, , , | Summary: The Sunyaev-Zel’dovich (SZ) effect from clusters of galaxies should yield a significant signal in cosmic microwave background(CMB) experiments at small angular scales ($ell ga 1000$). Experiments with sufficient frequency coverage should be able to remove much […]

Kavli Affiliate: Wayne Hu | First 5 Authors: Wayne Hu, , , , | Summary: Upcoming weak lensing surveys on wide fields will provide the opportunity to reconstruct the structure along the line of sight tomographically by employing photometric redshift information about the source distribution. We define power-spectrum statistics, including cross correlation between redshift bins, […]
