The Peculiar Motions of Early-Type Galaxies in Two Distant Regions VI: The Maximum Likelihood Gaussian Algorithm
R. P. Saglia, Matthew Colless, David Burstein +3
The EFAR project is designed to measure the properties and peculiar motions of early-type galaxies in two distant regions. Here we describe the maximum likelihood algorithm we deve…
The X-ray evolution of clusters of galaxies to z=0.9
L. R. Jones, H. Ebeling, C. Scharf +6
The evolution of the X-ray luminosity function of clusters of galaxies has been measured to z=0.9 using over 150 X-ray selected clusters discovered in the WARPS survey. We find no…
The peculiar motions of early-type galaxies in two distant regions - VII. Peculiar velocities and bulk motions
Matthew Colless, R. P. Saglia, D. Burstein +3
We present peculiar velocities for 84 clusters of galaxies in two large volumes at distances between 6000 and 15000 km/s in the directions of Hercules-Corona Borealis and Perseus-P…
The Infall Region of Abell 576: Independent Mass and Light Profiles
K. Rines, M. J. Geller, A. Diaferio +2
We describe observations of the nearby cluster of galaxies A576 beyond the virial radius and into the infall region. Using 1057 redshifts, we use the infall pattern in redshift spa…
Comparison of the ENEAR Peculiar Velocities with the PSCz Gravity Field
Adi Nusser, Luiz N. da Costa, Enzo Branchini +5
We present a comparison between the peculiar velocity field measured from the ENEAR all-sky catalog and that derived from the galaxy distribution of the IRAS PSCz redshift…
ENEAR Redshift-Distance Survey: Cosmological Constraints
S. Borgani, M. Bernardi, L. N. da Costa +5
We present an analysis of the ENEAR sample of peculiar velocities of elliptical galaxies, obtained with D_n-σdistances. We use the velocity correlation function to analyze the stat…
