CMB Cluster Lensing: Cosmography with the Longest Lever Arm
Wayne Hu, Daniel E. Holz, Chris Vale
We discuss combining gravitational lensing of galaxies and the cosmic microwave background (CMB) by clusters to measure cosmographic distance ratios, and hence dark energy paramete…
Cluster Mass Estimators from CMB Temperature and Polarization Lensing
Wayne Hu, Simon DeDeo, Chris Vale
Upcoming Sunyaev-Zel'dovich surveys are expected to return ~10^4 intermediate mass clusters at high redshift. Their average masses must be known to same accuracy as desired for the…
Primordial non-Gaussianity and Dark Energy constraints from Cluster Surveys
Emiliano Sefusatti, Chris Vale, Kenji Kadota +1
Galaxy cluster surveys will be a powerful probe of dark energy. At the same time, cluster abundance is sensitive to any non-Gaussianity of the primordial density field. It is there…
Potential sources of contamination to weak lensing measurements: constraints from N-body simulations
Catherine Heymans, Martin White, Alan Heavens +2
We investigate the expected correlation between the weak gravitational shear of distant galaxies and the orientation of foreground galaxies, through the use of numerical simulation…
Local Pancake Defeats Axis of Evil
Chris Vale
Among the biggest surprises revealed by COBE and confirmed by WMAP measurements of the temperature anisotropy of the CMB are the anomalous features in the 2-point angular correlati…
Finding Clusters in SZ Surveys
Chris Vale, Martin White
We use simulated maps to investigate the ability of high resolution, low noise surveys of the CMB to create catalogues of Clusters of galaxies by detecting the characteristic signa…
