weak lensing mass calibration of the atacama cosmology telescope equatorial sunyaev zeldovich cluster sample with the canada france hawaii telescope stripe 82 survey
Journal of Cosmology and Astroparticle Physics, 2016Co-Authors: Nick Battaglia, Alexie Leauthaud, Hironao Miyatake, Matthew Hasselfield, Megan Gralla, R Allison, J R BondAbstract:Mass calibration uncertainty is the largest Systematic Effect for using clusters of galaxies to constrain cosmological parameters. We present weak lensing mass measurements from the Canada-France-Hawaii Telescope Stripe 82 Survey for galaxy clusters selected through their high signal-to-noise thermal Sunyaev-Zeldovich (tSZ) signal measured with the Atacama Cosmology Telescope (ACT). For a sample of 9 ACT clusters with a tSZ signal-to-noise greater than five the average weak lensing mass is (4.8 +/- 0.8) x 10(14) M-circle dot, consistent with the tSZ mass estimate of (4.70 +/- 1.0) x 10(14) M-circle dot which assumes a universal pressure profile for the cluster gas. Our results are consistent with previous weak-lensing measurements of tSZ-detected clusters from the Planck satellite. When comparing our results, we estimate the Eddington bias correction for the sample intersection of Planck and weak-lensing clusters which was previously excluded.

anomalous parity asymmetry of the wilkinson microwave anisotropy probe power spectrum data at low multipoles
The Astrophysical Journal, 2010Co-Authors: Jaiseung Kim, P NaselskyAbstract:We have investigated non-Gaussianity of our early universe by comparing the parity asymmetry of the Wilkinson Microwave Anisotropy Probe (WMAP) power spectrum with simulations. We find that odd-parity preference of the WMAP data (2 ≤ l ≤ 18) is anomalous at 4-in-1000 level. We find it likely that low quadrupole power is part of this parity asymmetry rather than an isolated anomaly. Further investigation is required to find out whether the origin of this anomaly is a cosmological or a Systematic Effect. The data from Planck Surveyor, which has Systematics distinct from WMAP, will help us to resolve the origin of the anomalous odd-parity preference.
