Since only 5 optical synchrotron jets are known, line_4: detailed studies of the known jets are important to begin to understand line_5: this complex phenomenon. Indeed, the crucial questions for understanding line_6: the jet phenomenon remain unanswered. For example, are jets radiation beam line_7: or particle beams\? Are the radiating electrons accelerated locally where line_8: we see them in the optical, or are they tranported loss-free from the line_9: nucleus\? What is the confinement mechanism\? line_11: Polarization measurements are proposed to confirm the strong line_12: circumstantial evidence for the synchrotron emission from the jet. line_13: Spectral index measurements along the length of the jet will reveal line_14: details of the energy transport if the jet fits the standard scenarios. ! ! end of abstract general_form_proposers: lname: CRANE fname: PHILIPPE inst: EUROPEAN SOUTHERN OBSERVATORY country: GERMANY, WEST esa: N ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The Near UV Objective Prism will be used with the HST rotated line_2: to the appropriate position angle so the jet is perpendicular line_3: to the prism dispersion to provide a low dispersion spatially line_4: resolved spectrum of this jet. Since the jet is essentially line_5: unresolved perpendicular to its length, the spectrum will be line_6: relatively easy to interprete and will thus provide a good measure line_7: of the spectral index along the jet. ! question: 4 section: 1 line_1: The jet to be studied is only 0.6 arcsec long. The proposed observations line_2: take full advantage of the unique capabities of the FOC and of HST. In line_3: particular, the high spatial resolution coupled with the UV sensitivity line_4: will be exploited. Given the FOC spatial resolution of 22 milli-arcsec, line_5: the objective prism will include about 30 pixels along the jet in the line_6: brighter regions. This type of spatial resolution, needed to study the line_7: details of the spectral index along the jet, cannot be achieved with any line_8: but HST. The polarization measurements also require HST resolution. ! question: 7 section: 1 line_1: Although the reduction of this sort of data is not simple, we are in close line_2: contact with Peter Jakobsen who is THE expert on reducing these data. ! question: 9 section: 1 line_1: line_2: 1055 Imaging and Spectroscopy of M81 ( not related) line_3: 1056 Imaging and Spectroscopy of Spiral Galaxies(not related) line_4: 1057 Imaging and Spectroscopy of Elliptical Galaxies line_5: 1058 Optical Emission from Radio Lobes( not related) line_6: 1059 Gravitational Lenses (not related) line_7: 1061 Binary Pulsar PSR1913+16(not related) ! question: 10 section: 1 line_1: This is a GTO/AUG proposal, and thus the institutional arrangements remain line_2: the same for this as for the GTO science. ! !end of general form text general_form_address: lname: CRANE fname: PHILIPPE category: PI inst: EUROPEAN SOUTHERN OBSERVATORY addr_1: KARL-SCWARZSCHILD-STR. 2 city: D-8046 GARCHING BEI MUNCHEN country: GERMANY, WEST phone: +49-89-320-06-230 ! ! end of general_form_address records fixed_targets: targnum: 1 name_1: NGC3862 name_2: 3C264 descr_1: E,315,910 pos_1: RA = 11H 45M 5.038S +/- 0.1S, pos_2: DEC = +19D 36' 21.64" +/- 1.0" equinox: 2000.0 ! ! end of fixed targets !
