Mapping the Ages of Dying Radio Galaxies

Caption

Radio observations and spectral-age maps of remnant radio galaxies in the XMM–LSS field. The left panels show radio emission observed with uGMRT and MeerKAT overlaid on optical images, the middle panels show the measured radio spectra and best-fitting spectral-ageing models, and the right panels map the spectral ages of the radio-emitting plasma. These observations allow astronomers to reconstruct how the galaxies evolve after their central jets switch off.
