They serve as galactic nuclei.

Explanation:

A supermassive black hole (SMBH) is the largest type of black hole, in the order of hundreds of thousands to billions of solar masses (M☉), and is found in the centre of almost all currently known massive galaxies. In the case of the Milky Way, the SMBH corresponds with the location of Sagittarius A*.
