Dynamics of ``Small Galaxies'' in the Hubble Deep Field

Wesley N. Colley, Oleg Y. Gnedin, Jeremiah P. Ostriker +1

We have previously found in the Hubble Deep Field a significant angular correlation of faint, high color-redshift objects on scales below one arcsecond, or several kiloparsecs in m…

Two Dimensional Topology of Large Scale Structure in the Las Campanas Redshift Survey

Wesley N. Colley

We have measured the topology (genus) of the density distribution of large-scale structure observed in the Las Campanas Redshift Survey (LCRS). The LCRS is complete to magnitude 17…

A Robust Determination of the Time Delay in 0957+561A,B and a Measurement of the Global Value of Hubble's Constant

Tomislav Kundic, Edwin L. Turner, Wesley N. Colley +9

Photometric monitoring of the gravitational lens system 0957+561A,B in the g and r bands with the Apache Point Observatory (APO) 3.5 m telescope during 1996 shows a sharp g band ev…

Are Hubble Deep Field Galaxy Counts Whole Numbers?

Wesley N. Colley, James E. Rhoads, Jeremiah P. Ostriker +1

We compute the two-point angular correlation function and number-magnitude relation of Hubble Deep Field sources in order to assess their nature. We find that the correlation peaks…

The Evolution of Viscous Inclined Disks in Axisymmetric and Triaxial Galaxies

Wesley N. Colley, Linda S. Sparke

We have used a set of equations developed by Pringle (1992) to follow the evolution of a viscous twisted disk in a galaxy-like potential which is stationary or tumbling relative to…

Unlensing Multiple Arcs in 0024+1654: Reconstruction of the Source Image

Wesley N. Colley, J. Anthony Tyson, Edwin L. Turner

A unique reconstruction of the image of a high redshift source galaxy responsible for multiple long arcs in the z = 0.4 cluster 0024+1654 is obtained by inverse lensing. Deep B and…

A Sharp Event in the Image a Light Curve of the Double Quasar 0957+561 and Prediction of the 1996 Image B Light Curve

T. Kundic, W. N. Colley, J. R. Gott +7

CCD photometry of the gravitational lens system 0957+561A,B in the g and r bands was obtained on alternate nights, weather permitting, from December 1994 through May 1995 using the…
