| Summary:
We have carried out Chandra, HST, and VLA observations of four MOJAVE blazars
that have been previously classified as ‘hybrid’ (FR I/II) blazars in terms of
radio morphology but not total radio power. The motivation of this study is to
determine the X-ray emission mechanism in jets, these being different in FR I
and FR II jets. We detected X-ray jet emission with sufficient SNR in two
blazars viz. PKS 0215+015 and TXS 0730+504. We carried out spectral energy
distribution (SED) modeling of the broad-band emission from the jet regions in
these sources and found that a single synchrotron emission model is ruled out
due to the deep upper limits obtained from HST optical and IR data. The IC- CMB
model can reproduce the X-ray jet emission in both sources although the model
requires extreme jet parameters. Both our sources possess FR II like radio
powers and our results are consistent with previous studies suggesting that
radio power is more important than FR morphology in determining the emission
mechanism of X-ray jets.
