The Luminosity Function of Galaxies in SDSS Commissioning Data
SDSS Collaboration, M. R. Blanton
During commissioning observations, the Sloan Digital Sky Survey (SDSS) has produced one of the largest existing galaxy redshift samples selected from CCD images. Using 11,275 galax…
SDSS-RASS: Next Generation of Cluster-Finding Algorithms
R. Nichol, C. Miller, A. Connolly +17
We outline here the next generation of cluster-finding algorithms. We show how advances in Computer Science and Statistics have helped develop robust, fast algorithms for finding c…
The Infrared Surface Brightness Fluctuation Hubble Constant
Joseph B. Jensen, John L. Tonry, Rodger I. Thompson +5
We measured infrared surface brightness fluctuation (SBF) distances to an isotropically-distributed sample of 16 distant galaxies with redshifts reaching 10,000 km/s using the near…
Observational Constraints on Higher Order Clustering up to $z\simeq 1
István Szapudi, Marc Postman, Tod R. Lauer +1
Constraints on the validity of the hierarchical gravitational instability theory and the evolution of biasing are presented based upon measurements of higher order clustering stati…
CFHT Optical PDCS Survey II: Evolution in the Space Density of Clusters of Galaxies
B. P. Holden, C. Adami, R. C. Nichol +6
We present the first dynamical study of the optically selected Palomar Distant Cluster Survey (PDCS). We show that eleven out of twelve PDCS clusters we observed are real over-dens…
The CFH Optical PDCS survey (COP) I: The Data
C. Adami, B. Holden, F. J. Castander +5
This paper presents and gives the COP (COP: CFHT Optical PDCS; CFHT: Canada-France-Hawaii Telescope; PDCS: Palomar Distant Cluster Survey) survey data. We describe our photometric…
Shellflow. I. The Convergence of the Velocity Field at 6000 km/s
S. Courteau, J. A. Willick, M. A. Strauss +2
We present the first results from the Shellflow program, an all-sky Tully-Fisher (TF) peculiar velocity survey of 276 Sb-Sc galaxies with redshifts between 4500 and 7000 km/s. Shel…
A Definitive Optical Detection of a Supercluster at z = 0.91
L. M. Lubin, R. Brunner, M. R. Metzger +2
We present the results from a multi-band optical imaging program which has definitively confirmed the existence of a supercluster at z = 0.91. Two massive clusters of galaxies, CL1…
