Probing the velocity and spectral evolution along the eastern lobe of the microquasar SS 433
Abstract
We propose to perform Chandra ACIS-I observations of the non-thermal knots located in the eastern lobe of W50 associated with the Galactic microquasar SS 433. These knots are the likely counterparts of the recently detected VHE gamma-ray emission by HAWC, making the SS 433/W50 system a unique jet-driven PeVatron candidate. Chandra will provide the first high-resolution X-ray imaging data of our proposed region aimed to achieve: (1) proper motion measurement of the knots to determine the velocity profile in the eastern jet, and (2) spatially-resolved X-ray spectroscopy to characterize the spectral evolution along the jet. These observables uniquely obtained by new Chandra observations will test our model predictions for the jet dynamics, knot formation, and particle acceleration processes.
