Tavecchio Osservatorio Astronomico di Brera, Milano N ------------------------------------------------------------------------------------ Abstract We propose observations of a small sample of intermediate-redshift radio jets (2=3-4) tend to confirm the IC/CMB origin of the X-ray emission, the limited morphological information available due to the faintness of the radio emission prevents more detailed studies. Observations at intermediate z will bridge the gap, allowing us to study the role of both the increase of the CMB energy and intergalactic matter densities on the X-ray emission properties and physics of jets. ------------------------------------------------------------------------------------ Observations Description ------------------------ Each of the 3 targets require 1 orbit of F606W imaging. Assuming a radio-to-optical spectral index, $\alpha_{\rm ro}=0.9$ and normalizing to the radio fluxes, we expect a range of detections of 0.07 $\mu$Jy (18$\sigma$) for the faintest radio knots, to 0.64 $\mu$Jy (89$\sigma$) for the brightest. Conversely, we can probe $\alpha_{\rm ro}$ values down to $>$0.95 and $>$1.14 (5$\sigma$). Thus, a single filter observation is sufficiently sensitive to determine if the radio and X-ray points are from a single power-law component or if two spectral components are necessary (e.g., Sambruna et al. 2006). According to the WFC3 ETC, the 2 V~18 targets will take ~200 sec to saturate. We have put in a short (92-93 sec) exposure to obtain an unsaturated image. The third target, the faintest one, is not expected to saturate.
