Scientific Category 3. Proposal For 4. Proposal Type 5. Continuation ID QUASARS & AGN SAT/OS Sub Category GRAVITATIONAL LENSES ------------------------------------------------------------------------------------ 6. Principal Investigator Institution Country Telephone Philippe Crane EUROPEAN SOUTHERN OBSERVATOR GERMANY, W +49-89-320-06- ASTRONOMER/PHYSICIST ------------------------------------------------------------------------------------ 7. Abstract We intend to detect new features in gravitationally lensed QSO's. In particular, we will look for the predicted extra images, optical counter-parts to VLA and VLBI jets and if possible at the morphology of the deflecting mass. Quantitative knowledge of these is necessary for the astrophysical use of the phenomenon. ------------------------------------------------------------------------------------ 8.

Description of proposed observations. Exposures 3, 4, 6, and 7 should be in cycle 1 Exposures 1, 2, and 5 should be in cycle 2 NOTE: THE ABOVE TEXT IN SECTION 3 IS FROM AN EARLIER PROPOSAL AND DOES NOT APPLY TO THIS SAT VERSION OF THE PROPOSAL. ONLY EXPOSURE LINE 1 EXISTS IN THIS VERSION OF THE PROPOSAL AND IT IS IN CYCLE 0. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. If we choose the option to make an f/288 exposure of Q0957+561 we want the position angle to be -13D so that the expected optical jet falls entirely within the f/288 field of view. NOTE: THE ABOVE COMMENT IN SECTION 5 IS FROM AN EARLIER VERSION OF THE PROPOSAL. Q0957+561 IS NOT THE TARGET IN THE ONE EXPOSURE IN THIS SAT PROPOSAL. ------------------------------------------------------------------------------------ 12. ------------------------------------------------------------------------------------ 13. Known gravitationally lensed QSO's will be imaged to look for expected subsidiary images and optical counterparts to radio jets. ------------------------------------------------------------------------------------ 11.
