Overview
- Peer-reviewed analysis in Monthly Notices of the Royal Astronomical Society identifies J1007+3540 as an episodic active galactic nucleus that has reactivated after roughly 100 million years.
- Radio maps show a compact, bright core jet nested within older, faded plasma, marking a restart of activity.
- Interaction with the host cluster’s hot gas is compressing and bending the outflows, including a distorted northern lobe with curved backflow.
- uGMRT spectra reveal an ultra-steep region of very old, energy-depleted particles and a long faint tail of diffuse emission stretching southwest.
- Researchers plan deeper, higher-resolution observations to probe the nucleus and track how the revived jets propagate through the turbulent environment.
