  "abstract": "We present a 13 yr Chandra High Resolution Camera (HRC-I) study of the M87 jet, using point-spread function deconvolution to achieve unprecedented subarcsecond X-ray resolution of its kiloparsec-scale structure and temporal evolution. The deconvolved images reveal previously blended structures within the jet, including two components in HST-1 and complex morphology in downstream knots. Flux measurements reveal a global decrease in X-ray emission across the jet of up to 84%, consistent with synchrotron cooling. Modeling the fading yields minimum magnetic field strengths of ∼324–1006 μ G for HST-1 and ∼41–115 μ G for knot A. Consistent with synchrotron cooling, multiwavelength comparisons with the Atacama Large Millimeter Array, James Webb Space Telescope, and Hubble Space Telescope show that the principal X-ray structures closely match the jet width and knot locations observed at lower energies, while the X-ray emission is generally shifted upstream. Proper-motion measurements show that jet features exhibit both quasistationary and superluminal apparent motions, reaching up to 4.8 c for HST-1, and also demonstrate that unresolved component blending can substantially bias inferred velocities. These results demonstrate the unique capability of high-resolution Chandra X-ray imaging over long temporal baselines to resolve the evolving substructure of relativistic jets and to probe the particle acceleration and energy dissipation processes that shape their dynamics.",
