Disk and Bulge Morphology of WFPC2 galaxies: The HST Medium Deep Survey database

Kavan U. Ratnatunga, Richard E. Griffiths, Eric J. Ostrander

Quantitative morphological and structural parameters are estimated for galaxies detected in HST observations of WFPC2 survey fields. A modeling approach based on maximum likelihood…

The Top Ten List of Gravitational Lens Candidates from the HST Medium Deep Survey

K. U. Ratnatunga, R. E. Griffiths, E. J. Ostrander

A total of 10 good candidates for gravitational lensing have been discovered in the WFPC2 images from the HST Medium Deep Survey (MDS) and archival primary observations. These cand…

The HST Medium Deep Survey Cluster Sample: Methodology and Data

E. J. Ostrander, R. C. Nichol, K. U. Ratnatunga +1

We present a new, objectively selected, sample of galaxy overdensities detected in the Hubble Space Telescope Medium Deep Survey. These clusters/groups were found using an automate…

The Serendipitous Discovery of a Group or Cluster of young Galaxies at z=2.40 in Deep Hubble Space Telescope WFPC2 Images

Sebastian M. Pascarelle, Rogier A. Windhorst, Simon P. Driver +2

We report the serendipitous discovery of a group or cluster of young galaxies at 2.40 in a 24-orbit HST/WFPC2 exposure of the field around the weak radio galaxy 53W002. Po…

The morphological mix of field galaxies to I=24.25 magnitudes (b=26 magnitudes) from a deep Hubble Space Telescope WFPC2 image

Simon P. Driver, Rogier A. Windhorst, Eric J. Ostrander +3

We determine the morphological mix of field galaxies down to mag ( mag) from a single ultradeep HST WFPC2 image in both the and $I_{81…

New "Einstein Cross" Gravitational Lens Candidates in HST WFPC2 Survey Images

Kavan U. Ratnatunga, Eric J. Ostrander, Richard E. Griffiths +1

We report the serendipitous discovery of ``Einstein cross'' gravitational lens candidates using the Hubble Space Telescope. We have so far discovered two good examples of such lens…
