Abstract:
We propose ACIS-S observation of a high redshift resolved X-ray jet to study emission processes responsible for the observed X-rays. Chandra will probe hard X-ray (2.5-30 keV) rest frame energies critical for studies of jet and particle acceleration physics. The source was observed in Cycle 4. Our new observation ~20 years (rest frame ~4.4 years) later will provide a baseline for the variability test of the X-ray emission process. This jet is propagating in a high-z environment and our studies will have potential insights on feedback.
