Overview
- Radio maps show a bright, compact inner jet embedded inside faded, expanded lobes that together reach nearly a million light-years.
- The morphology identifies J1007+3540 as an episodic active galactic nucleus with multiple past eruptions separated by long quiet phases.
- A compressed northern lobe with a curved backflow marks strong interaction with the intracluster medium that bends and distorts the outflows.
- uGMRT spectra reveal an ultra‑steep index in the compressed region, indicating very old, energy‑depleted particles shaped by the cluster environment.
- The research team plans deeper, higher‑resolution observations to trace the restarted jets and better constrain the system’s duty cycle and feedback.
