Principal Investigator Institution Country Telephone J. roger P Angel UNIVERSITY OF ARIZONA USA 602-621-7661 ------------------------------------------------------------------------------------ 7. Abstract Measurement of the spectrum of polarization has proven to be a powerful tool in deciphering emission processes and source geometry in AGN. This program will extend these observations into the UV below 3000A. ------------------------------------------------------------------------------------ 8.

GENERAL FORM Proposal 3270c PI: J. roger P Angel Proposal Title: SPECTROPOLARIMETRY OF QSOS, BLAZARS AND AGN: CYCLE 2 OBSERVATIONS ------------------------------------------------------------------------------------ 1. Proposers: Proposers Institution Country ESA ------------------------------------------------------------------------------------ Dr. Edward Beaver UC, SAN DIEGO USA Dr. E. Margaret Burbidge UC, SAN DIEGO USA Dr. J. Roger P Angel UNIVERSITY OF ARIZONA USA Dr. Bruce Margon WASHINGTON, UNIVERSITY OF USA Dr. Holland C Ford JOHNS HOPKINS UNIVERSITY USA Dr. Frank Bartko MARTIN MARIETTA CORPORATION USA Dr. Arthur F Davidsen JOHNS HOPKINS UNIVERSITY USA Dr. Richard J Harms APPLIED RESEARCH CORPORATION USA Dr. Ralph Bohlin SPACE TELESCOPE SCIENCE USA INSTITUTE ------------------------------------------------------------------------------------ 3. Description of proposed observations. The spectrum of polarization for a number of AGN of diverse type will be observed with the FOS spectropolarimeter. Targets include both low and high polarization QSOs, Seyfert galaxies, and BL Lac objects. ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. The ST is needed to do spectropolarimetry below 3000A. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. Blazars are so rapidly variable that any observation must be completed within a few hours. The SV prerequisite programs for all FOS observations in this program are: Prop ID 2195 FOS Target Acquisition Tests All observations Prop ID 1317 Int./Ext. Wavelength Offsets 1st target Prop ID 1318 Spectral Flat Fields 1st target Prop ID 1320 Absolute Spectrophotometry 1st visit of bright targets Prop ID 1430 Polarimetric y-bases (lines 103,104) and polarimetric wavelength calibrations (lines 105,106) ------------------------------------------------------------------------------------ 13. Spectropolarimetry of QSOs, BL Lac objects, Blazars, Seyferts, and other AGN, are obtained in order to decipher emission and scattering processes and source geometry. ------------------------------------------------------------------------------------ 11.
