The peculiar motions of early-type galaxies in two distant regions - VII. Peculiar velocities and bulk motions

Colless, Matthew; Saglia, R.P; Burstein, David; Davies, R.L; McMahan, Robert K. Jr; Wegner, Gary


We present peculiar velocities for 85 clusters of galaxies in two large volumes at distances between 6000 and 15000kms-1 in the directions of Hercules-Corona Borealis and Perseus-Pisces-Cetus (the EFAR sample). These velocities are based on Fundamental Plane (FP) distance estimates for early-type galaxies in each cluster. We fit the FP using a maximum likelihood algorithm which accounts for both selection effects and measurement errors, and yields FP parameters with smaller bias and variance...[Show more]
