摘要：

With around 20000 QSOs, the 2dF QSO Redshift Survey (2QZ) is currently the largest individual QSO survey. A prime aim of 2QZ is to determine the form of QSO clustering, using correlation function and power spectral analyses, on large scales out to beyond the power spectrum turnover to primordial form predicted in CDM cosmologies. Here we present the first measurement of the QSO power spectrum, using the 2QZ, and investigate a new constraint on Omega and Lambda from redshift-space distortions in the power spectrum.
