It has been argued that supermassive black holes (BHs) coevolve with the central parts of galaxies as a result of the common fuel for both the BH and star formation in the galaxy central region, as supported by the particularly significant relation between BH growth and the central mass density within 1 kpc ( found among star-forming galaxies. In the context of this scenario, one would naturally expect a close observational link between active galactic nucleus (AGN) activity and star formation activity in the central regions, e.g., the surface star formation rate density in the central 1 kpc region ( as a manifestation of coeval growth. With ≈ 3000 galaxies in the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey that have X-ray coverage from SRG/eROSITA, or ̧handra, we studied how the X-ray AGN fraction varies with We found that the fraction of X-ray AGNs with relatively higher specific BH accretion rates increases with consistent with the expectation. A comparison of the mean star formation rate surface density ( profiles of the host galaxies of these AGNs and normal galaxies sharing similar properties reveals elevated in AGN hosts across the entire central region. As for optically selected AGNs, their hosts also tend to show high in the central regions on average compared to normal galaxies, but they differ from X-ray AGNs in terms of the trend of AGN fraction versus which can be explained by selection effects. While these general trends all support the coeval growth scenario, they do not contradict observational evidence for AGN feedback suppressing star formation, as the time-averaged effects of such feedback might be modest in the local Universe.
