An extended dust disk in a spiral galaxy; An occulting galaxy pair in ANGST
B. W. Holwerda, W. C. Keel, B. Williams +2
We present an analysis of an occulting galaxy pair, serendipitously discovered in ACS Nearby Galaxy Survey Treasury (ANGST) observations of NGC 253 taken with Hubble Space Telescop…
Structure and Evolution of the Opacity of Spiral Disks
B. W. Holwerda, R. A. Gonzalez, W. C. Keel +3
The opacity of a spiral disk due to dust absorption influences every measurement we make of it in the UV and optical. Two separate techniques directly measure the total absorption…

Spiral Disk Opacity from Occulting Galaxy Pairs in the Sloan Digital Sky Survey
B. W. Holwerda, W. C. Keel, A. Bolton
A spiral galaxy partially ovelapping a more distant elliptical offers an unique opportunity to measure the dust extinction in the foreground spiral. From the Sloan Digital Sky Surv…
HST Observations of Young Star Clusters in Interacting Galaxies
K. D. Borne, W. C. Keel, P. N. Appleton +3
We present early results from the analysis of HST imaging observations for several pairs of interacting galaxies. We include two cases that were specifically chosen to represent a…
Deep HST/PC Images of a Young Radio Galaxy at z=2.390
Rogier A. Windhorst, William C. Keel, Sebastian M. Pascarelle
We present deep 63-orbit HST/PC images at ~0.06" FWHM resolution in the filters B_450, V_606 & I_814 - as well as in redshifted Lya - of the radio source LBDS 53W002, a compact nar…
