New Dimensions in Cosmic Lensing
Andy Taylor
I review the current status of combing weak gravitational lensing with depth information from redshifts as a direct probe of dark matter and dark energy in the Universe. In particu…
Reconstructing PSCz with a Generalised PIZA
Helen Valentine, Will Saunders, Andy Taylor
We present a generalized version of the Path Interchange Zel'dovich Approximation (PIZA), for use with realistic galaxy redshift surveys. PIZA is a linear particle-based Lagrangian…
Density and Velocity Fields from the PSCz Survey
Will Saunders, Enzo Branchini, Luis Teodoro +17
We present the results for the predicted density and peculiar velocity fields and the dipole from the PSCz survey of 15,000 IRAS galaxies over 84% of the sky. We find a significant…
Reconstructing PSCz with a Generalized PIZA
Helen E. M. Valentine, Will Saunders, Andy Taylor
We present a generalized version of the Path Interchange Zel'dovich Approximation (PIZA; Croft and Gaztanaga 1997; hereafter CG97), which may be used to reconstruct density and vel…
Cosmological Parameter Estimation from the CMB
Andy Taylor, Alan Heavens, Bill Ballinger +1
We discuss the problems of applying Maximum Likelihood methods to the CMB and how one can make it both efficient and optimal. The solution is a generalised eigenvalue problem that…
The clustering of warm and cool IRAS galaxies
Bob Mann, Will Saunders, Andy Taylor
We use a series of statistical techniques to compare the clustering of samples of IRAS galaxies selected on the basis of their far-infrared emission temperature, to see whether a t…
