A black hole.
A supermassive black hole if my memory serves me correctly.
I believe that some theorize that a black hole is a crucial and necessary component in the formation of galaxies.
I don't know how widely accepted it is though.

The general consensus is that a black hole resides at the galactic center.
There are some very good reasons why a black hole cannot exist
The galactic center is inhabited by a mass of neutron density matter.
It is difficult to imagine how stars merge as they approach the galactic center,but a galaxy is an end stage in the evolution of a finite universe
As neutron density matter increases in density it either becomes a black hole {which is not possible} so the collapse of the matter at the galactic center must be the action that contributes to the contraction of the galaxy.
If a black hole could exist it would eventually accrete all the matter in the universe and sit for eternity doing nothing.

Yes,the engine which drives a galaxy is in fact a black hole. This is no longer theory as it is an observable phenomenon now that we know what to look for. As an example, the andronima galaxy next to us was thought to be very peaceful and basically at rest. Now we know that a super massive black hole powers it and that eventually it will collide with our own Milky Way. The question now is which galaxies are powered by regular black holes and which ones are powered by super massive ones.

a great huge black hollow is understood to be on the middle of each and every galaxy, although no longer each and every galaxy has a "whirlpool" trend. those styles of galaxies are talked approximately as "spiral" (our Milkyway is unquestionably one of them case in point) and there trend ought to in easy terms be led to by potential of a black hollow on the middle. the different styles of galaxies are Elliptical and odd galaxies, and that they have not got a spiral trend.

The letter "L."
Seriously. Look "a galaxy" There's three letters on each side of the "L." "L" is in the dead center.

Black hole, as said above, but im sure if technology will get more advanced (which im sure it will), we will have 100% guarentee on what it is, how its made, etc.
