Principal Investigator Institution Country Telephone Prof. John B. Hutchings DOMINION ASTROPHYSICAL OBSER CANADA (604) 363-0018 ------------------------------------------------------------------------------------ 7. Abstract WF/PC will be used to image two objects of interest in various wavelengths. 1) The quasar 2305+187 which is marginally resolved as interacting from the ground; 2) The galaxy NGC 4874 which is marginally resolved as having a bright nucleus and dust lane from the ground. ------------------------------------------------------------------------------------ 8.

GENERAL FORM Proposal 1157c PI: Prof. John B. Hutchings Proposal Title: IMAGING OF DISTANT ACTIVE GALAXIES -- CYCLE 1 ------------------------------------------------------------------------------------ 1. Proposers: Proposers Institution Country ESA ------------------------------------------------------------------------------------ A. C. Gower VICTORIA, UNIVERSITY OF CANADA John B. Hutchings DOMINION ASTROPHYSICAL CANADA OBSERVATORY ------------------------------------------------------------------------------------ 3. Description of proposed observations. 2305+187 and neighboring galaxies will be imaged with the WFC using filters to isolate continuum and emission line regions. NGC 4874 will be imaged with the PC in selected continuum band filters. ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. ST provides the high spatial resolution. ------------------------------------------------------------------------------------ 7. Data reduction and analysis plans. Analysis at DAO using extensive image processing software. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). All support provided. ------------------------------------------------------------------------------------ 13. WFC images of quasar and companion 2305+187 in several continuum and line wavelengths. PC images of NGC 4874 in continuum wavelengths. ------------------------------------------------------------------------------------ 11. Address Information Name: JOHN B.
