Abstract
The cold-dark-matter model makes very specific predictions for large scale structure. Here I compare these predictions with some observations of large scale structure in the nearby universe. I review a number of tests described in more detail elsewhere (Kaiser and Lahav, 1988a, b). These comprise a comparison of the cold-dark-matter predictions with angular dipoles of IRAS galaxies and bulk flow solutions; an improved determination of the bias parameter from a variant of Gott’s method; and a comparison of both angular dipoles and acceleration vector derived from the IRAS 2Jy redshift survey with the density field predicted from modelling of the peculiar velocity field. A new method for estimating the peculiar velocity autocorrelation function is described and applied to a selection of available catalogues. I conclude with a discussion of the connection between biased theories for galaxy formation and the distance estimates used to obtain peculiar velocities.
