Description
We study the spatially resolved star formation, gas excitation, and outflow properties of AGN in the full MaNGA survey. These AGN are classified into Type 1, Type 2, infrared, and radio AGN based on their optical spectra, mid-infrared colours, and LoTSS photometry. We estimate the AGN contribution to emission lines, infrared and radio luminosities to trace the power of the narrow or broad line regions, the torus, and the radio jets of the AGN respectively. Compared to mass-matched control samples, we find enhanced nuclear star formation in infrared, Type 1, and Type 2 AGN, and suppressed star formation in radio AGN. Outflow features are also more prominent in infrared and Type 1 AGN, especially in inner radial bins. Stronger gas excitation is found in all AGN populations, particularly within the central 1 kpc region. Stronger AGN show more pronounced effects. Our results support a scenario in which high Eddington ratio AGN with strong emission line regions and dust torus evolve into low accretion mode radio AGN, while their host galaxies transition from a nuclear starburst stage to a quiescent phase.
