The Circumnuclear Impact of Accreting Black Holes at z~0

The centres of most galaxies are the habitat for supermassive black holes (SMBH) that comply with SMBH scaling relationships regardless of whether or not they are accreting. The scaling relationships imply that the growth of the SMBH and the growth of the galaxy bulge go hand in hand, and are understood to be a consequence of feedback between hot outflows generated by the accreting system and star formation in the host galaxy bulge. However, the exact mechanisms and the circumstances under which positive and negative feedback dominate are not understood. Some results from multi-frequency studies of accreting SMBH at z~0 that address the question will be discussed.
