Abstract As part of our ongoing investigation of the M87 jet, we have obtained unprecedented high resolution images of the jet using the FOC. These data show structures with a FWHM as small as 0.03", and provide a unique opportunity to study proper motions and structural changes of the jet. We will compare Cycle 6 FOC and WFPC2 images with Cycle 4 and 5 observations to measure secular changes and motions in the jet and nucleus. Typical speeds found with VLA observations range from 0.5c to 3c, while our Cycle 4 and 5 data already show speeds between 2c and 6c for the fastest components. Since the optical emission is more concentrated near the jet axis than the radio emission, the optical data will give velocity information on a different physical volume closer to the jet axis, and show whether there are strong velocity gradients across and within the jet. Secular changes in luminosity and polarization are also likely as the knots move, which will provide information on the evolution of the electron energy distribution and magnetic fields. We propose polarization measurements to map the magnetic field structure and its evolution in the first few pc of the jet near the ``central engine.'' We were awarded Cycle 5 time to carry out observations as the foundation of an annual monitoring program, and recieved a provisional award of time in Cycles 6 and 7; herein we request continuation of this program. ------------------------------------------------------------------------------------ 6775( 5) - 05/16/96 13:43 - [ 2] Observations Description ------------------------ FOC: Images of the jet using 3 pointings (nucleus + knots D&E; knots E,F,I; and knots I,A,B,C) in the 512x512 format with the F342W filter. At the bright nucleus exposures are also made utilizing F2ND and F4ND. Polarization sensitive images (+POL0, +POL60, +POL120) will be taken for the nucleus and knot A regions. The ``face-on" COSTAR reflections do not hinder polarization measurements, especially if polarization levels are as high as here, tens of percent. The feasibility is also demonstrated by our published results on Seyfert galaxies (Capetti et al. 1995). WFPC2: Images of the nucleus and jet with the PC through F814W filter. The proper motions measured by the VLA would easily be detected by the F342W FOC observations. For example, VLA results for a bright feature in knot D, which is 3" from the nucleus, show speeds up to 3c or 0.012" per year. The F342W image contains about 10000 counts in this region which has a scale size ~0.1". From signal-to-noise considerations a velocity accuracy of about (0.1")(square)rt(2)/(square)rt(10000)/3 = 0.0015" per year would be obtained between just the Cycle 4 and 5 observations, giving a velocity accuracy of ~0.3c for this feature in just one year. For Knot A the velocity accuracy would be about ten times better, due to larger total counts while the sharp ``edge" of knot A has a similar thickness ~0.1", and even finer internal structures. Alignment of images from different epochs will be aided by stars and globular clusters which are readily visible in the Cycle 4 FOC images (in contrast to the pre-COSTAR images where these features are invisible). The F814W WFPC2 observations will give spectral information and provide an independent motion measurement. Systematic uncertainties due to distortion will be largely eliminated by placing the jet on the same detector area for all epochs. We propose to extend these observations to future cycles in order to provide a longer time baseline for velocity measurements, and to monitor brightness changes in the jet. The essence of our proposal is monitoring. We have chosen a program which demonstrates optimal SNR for a given exposure time, in the blue with the FOC, and in the far -red with WFPC2, and uses the most straightforward imaging polarimetry. Therefore we propose to repeat this identical sequence in each of Cycles 6 and 7. We will use WFPC2 in parallel with the FOC to increase the sample of globular clusters already observed (see results in G0-5477 below, also Elson and Santiago 1995). Real Time Justification ----------------------- Interactive acquisitions and real-time uplinks are requested for the FOC observations, since the nominal pointing accuracy (2 arcsec.) is a large fraction of the FOC field-of-view (7 x 7 arcsec.). The jet is 20 arcseconds long, so that three accurately placed FOC fields will be needed to image the entire target.
