Principal Component Analysis of PSF Variation in Weak Lensing Surveys
Mike Jarvis, Bhuvnesh Jain
We introduce a new algorithm for interpolating measurements of the point-spread function (PSF) using stars from many exposures. The principal components of the variation in the PSF…
Effects of halo substructure on the power spectrum and bispectrum
Derek Dolney, Bhuvnesh Jain, Masahiro Takada
We study the effects of halo substructure and a distribution in the concentration parameter of haloes on large-scale structure statistics. The effects on the power spectrum and bis…
Detection of Cosmic Shear from STIS Parallel Archive Data: Data Analysis
J. -M. Miralles, H. Haemmerle, N. Pirzkal +6
In June 1997, parallel observations using the Space Telescope Imaging Spectrograph (STIS) on the HST started to be taken in substantial numbers along many different lines-of-sight.…
Cosmic Shear and Clusters of Galaxies
Y. Mellier, L. van Waerbeke, T. Erben +9
The first detections of cosmic shear signal reported recently by 4 independent groups cover angular scales between one and 10 arcmin. On those scales, the cosmic shear is a signatu…
Cosmic Shear with the VLT
R. Maoli, Y. Mellier, L. van Waerbeke +5
We report on the detection of cosmic shear on angular scales of 1.3-6.5 arcmin using 45 independent empty fields observed with the Very Large Telescope (VLT). This result confirms…
Cosmic Shear with the CFHT
L. van Waerbeke, Y. Mellier, T. Erben +10
We present results of our cosmic shear survey in progress at the Canada- France-Hawaii Telescope (CFHT). We analysed 1.7 sq. degrees of data, out of which we measured a significant…
