How fast is the Milky Way’s central black hole? A scientist’s revelation on the epoch of darkening and growth of galaxies
From the brightness of the bagel of light, researchers have estimated how quickly matter is falling onto Sagittarius A*—the name given to the Milky Way’s central black hole. The answer is that it’s not quick. The universe is getting jammed up by a little trickle, said a scientist at Yale University. Somehow only a thousandth of the matter that’s flowing into the Milky Way from the surrounding intergalactic medium makes it all the way down and into the hole. Natarajan said that it was revealing a huge problem. Where is this gas going? What is happening to the flow? It is clear that our understanding of black hole growth is not correct.

The Effects of Quasar Feedback on the Growth of Small Galaxies and Their Hosts: How Large is the Black Hole?
Di Matteo, T., Springel, V. & Hernquist, L. Energy input from quasars regulates the growth and activity of black holes and their host galaxies. Nature 433, 604–607 (2005).
Stellar feedback, which occurs when a star explodes as a supernova, is known to have similar effects as AGN feedback on a smaller scale. These stellar engines are easily big enough to regulate small “dwarf” galaxies, whereas only the giant engines of supermassive black holes can dominate the evolution of the largest “elliptical” galaxies.
The correlation is surprising when you consider that the black hole—big as it is—is a scant fraction of the galaxy’s size. TheSagittarius A* weighs about 4% of the world’s suns, while the Milky Way holds 1.5 trillion solar rays. The black hole’s gravity is restricted by its strength in the area around the core of the galaxy.
