The impact of unresolved binaries on searches for white dwarfs in open clusters
Kurtis A. Williams
Many open clusters have a deficit of observed white dwarfs (WDs) compared with predictions of the number of stars to have evolved into WDs. We evaluate the number of WDs produced i…
Determination of the Dark Matter Profile of Abell 2199 from Integrated Starlight
Daniel D. Kelson, Ann I. Zabludoff, K. A. Williams +3
We have obtained deep, long-slit spectroscopy along the major axis of NGC 6166, the cD galaxy in the cluster Abell 2199, in order to measure the kinematics of intracluster starligh…
The Velocity Function of Galaxies
Anthony H. Gonzalez, Kurtis A. Williams, James S. Bullock +2
We present a galaxy circular velocity function, Psi(log v), derived from existing luminosity functions and luminosity-velocity relations. Such a velocity function is desirable for…
