Mildly Suppressed Star Formation in Central Regions of MaNGA Seyfert
  Galaxies
  Negative feedback from accretion onto super-massive black holes (SMBHs), that
is to remove gas and suppress star formation in galaxies, has been widely
suggested. However, for Seyfert galaxies which harbor less active, moderately
accreting SMBHs in the local universe, the feedback capability of their black
hole activity is elusive. We present spatially-resolved H$\alpha$ measurements
to trace ongoing star formation in Seyfert galaxies and compare their specific
star formation rate with a sample of star-forming galaxies whose global galaxy
properties are controlled to be the same as the Seyferts. From the comparison
we find that the star formation rates within central kpc of Seyfert galaxies
are mildly suppressed as compared to the matched normal star forming galaxies.
This suggests that the feedback of moderate SMBH accretion could, to some
extent, regulate the ongoing star formation in these intermediate to late type
galaxies under secular evolution.
