Baum Rochester Institute of Technology N ------------------------------------------------------------------------------------ Abstract We propose for deep Chandra-HST observations of 3 hybrid MOJAVE quasars. As these sources have jets with different powers (Fanaroff-Riley type I & II) on either side of the central engine they could be the touchstone for ideas put forth to explain the question of the FR dichotomy and the nature of AGN jets in general. These deep observations will constrain unambiguously the X-ray emission mechanisms in these jets through the construction and modeling of broad-band SEDs at multiple jet positions. The X-ray imaging may reveal asymmetries in the hot gas on either side of the AGN, telling us about jet propagation in low/high power sources. The lack of such features may provide support to the idea of highly magnetized jets, which could be examined further through broad-band SED modeling. ------------------------------------------------------------------------------------ Observations Description ------------------------ We will observe the 3 quasars with arcsecond-scale radio jets, viz., 1045-188, 1849+670 and 2216-038, through the Wide Field Camera 3 (WFC3) on board HST, through the F160W (IR channel) and the F475W (UVIS channel) filters. The aim is to detect optical emission at various locations or knots along the jets of these quasars. Spectral index images will be made for these jet knots to understand the jet emission mechanism(s). Each target will be observed through each of the 2 filters (F160W and F475W) for 1 HST orbit each, giving a total of 6 orbits. Each orbit/visit is divided into 3 (sub-)exposures to create a 3-point LINE DITHER pattern.
