Weak Lensing Constraints on Cluster Structural Parameters
Jeffrey A. Willick, Nikhil Padmanabhan
We study the reliability of dark matter (DM) profile determinations for rich clusters of galaxies based on weak gravitational lensing measurements. We consider three functional for…
The Stanford Cluster Search for Distant Galaxy Clusters
Jeffrey A. Willick, Keith L. Thompson, Benjamin F. Mathiesen +3
We describe the scientific motivation behind, and the methodology of, the Stanford Cluster Search (StaCS), a program to compile a catalog of optically selected clusters of galaxies…
A Determination of the Hubble Constant from Cepheid Distances and a Model of the Local Peculiar Velocity Field
Jeffrey A. Willick, Puneet Batra
We present a measurement of the Hubble Constant based on Cepheid distances to 27 galaxies within 20 Mpc. We take the Cepheid data from published measurements by the Hubble Telescop…
Cosmic Velocities 2000: A Review
Jeffrey A. Willick
I review the status of cosmic velocity analysis as of January 2000, with an emphasis on two key questions: (1) What is the scale of the largest bulk flows in the universe? and (2)…
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…
The Low Resolution Spectrograph of the Hobby-Eberly Telescope II. Observations of Quasar Candidates from the Sloan Digital Sky Survey
D. P. Schneider, Gary J. Hill, X. Fan +1
This paper describes spectra of quasar candidates acquired during the commissioning phase of the Low-Resolution Spectrograph of the Hobby-Eberly Telescope. The objects were identif…
