The emission process for these objects has become the source of much debate, with both synchrotron and inverse-Compton processes possible, and with implications that impact not only on jet physics but also cluster and galaxy feedback modells. To obtain the best constraints on the jet physics it is critical to study long, relatively nearby jets. We therefore propose deep Chandra + HST observations of 3C 111, which has an extraordinary, 2-arcminute long X-ray jet, . We will constrain the X-ray and optical morphologies of the knot and hotspots, and obtain X-ray spectra and broadband spectral energy distributions for all components. This will constrain the emission mechanism and the evolution of jet parameters as a function of distance from the AGN. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will obtain images of 3C 111, its jet, counterjet and hotspots with the WFC3/UVIS (F850LP) and WFC3/IR (F160W). This will allow us to characterize all jet components as well as the hotspots in the optical and near-IR, obtain morphological information, and also optical and broadband spectral energy distributions. The latter will allow the fitting of synchrotron emission models. One image suffices to obtain the entire system in with WFC3/UVIS. However, to put both hotspots within the field, we are forced to have a very tight constraint on ORIENT (+/- 5 degrees). While we realize that this impacts schedulability, it is very important to have both hotspots, as this will allow us to fit relativistic beaming models, a key part of our project. The optimal roll angle (ORIENT) for WFC3/IR is identical to that for WFC3/UVIS. However, due to the smaller field of view two images are necessary to obtain both hotspots in the IR channel. We have kept both channels in the same visit for simplicity. As we have specified the point positions in RA, Dec rather than via POS TARGs, 13114( 4) - 09-Oct-2012 18:00:41 - [ 2] and the important thing is to fit the entire jet and lobes in the field of view, we can allow rotations of the ORIENT to multiples of 90 degrees.
