Chandra X-ray Observatory provides a great amount of data related to X-ray jets associated with quasars. The jets are common and they
constitute the largest scale black hole activity phenomenon, as they
transport a good amount of the quasars power to distances hundreds
kiloparsec away from the central engine. There have been several
models proposed to describe X-ray emission processes of large scale
jets and it is becoming clear that a "two-zone" jets model, with inner
relativistic "proper" jet (spline) and an outer "boundary" layer
(cocoon), is required to explain the data. We present two examples of
quasars jets at redshift z 1. They are different in physical size and
age, and are located in different intergalactic environments. We
discuss these jets properties in the context of the black hole
activity and evolution. We propose that the intermittent black hole
activity is imprinted in the jets structure as well as in the
interstellar medium. We discuss the consequences of such activity
related to the quasar power and overall impact of the jet on the
environment.
