Abstract: We report the latest results from our Chandra quasar jet survey, the largest such survey yet conducted. X-ray emission is detected from over 60% of the jets. This emission is interpreted through a model in which X-rays are produced by inverse Compton scattering of the cosmic microwave background (IC-CMB). The IC-CMB model indicates that the jets are aligned within 5–15° of the observed line of sight. To test this model we consider the distribution of the ratio of the X-ray and radio fluxes, R, with redshift. IC-CMB predicts that R should scale with redshift as (1 + z)a with a = 1.5–2.0. A fit to the distribution of R values in our survey gives a = 0.8 ± 1.7 at 90% confidence, consistent with the IC-CMB model. However, the scatter in R is large, even within a narrow redshift range, suggesting that there is considerable scatter in the intrinsic properties of the jets.
