Unprecedented X‑ray Detail
An international team of astronomers has combined data from NASA’s Chandra X‑ray Observatory with modern image‑processing algorithms to produce the most detailed X‑ray image to date of the jet launched by the supermassive black hole at the core of galaxy M87.
Data set and technique
The study utilizes more than three hundred individual Chandra exposures taken over several years, covering the 0.5–7 keV energy band. By co‑adding the observations and applying de‑convolution methods, instrumental noise was minimized and spatial resolution was significantly enhanced.
Insights into jet structure
The resulting map reveals fine filamentary structures and multiple bright knots along the jet, suggesting localized particle‑acceleration sites. The plasma is confirmed to flow at speeds close to light, with magnetic fields playing a dominant role in shaping the emission.
Implications for astrophysics
These high‑resolution observations provide critical constraints for theoretical models of relativistic jet formation and for the interaction between the black hole, its accretion disk, and the surrounding interstellar medium. The findings also establish a benchmark for upcoming high‑energy missions.
