How can stars form in the center of the galaxy?

Are there any models that explain star formations at the center of the Galaxy?

Is the current scientific theory of galaxy formation wrong?

@davepamn you have the best questions. As far as I've read the gas in the protogalaxy loses energy and gains density. Gas clouds form within the protogalaxy and while moving around in orbits, collide. When this happens the gas is compressed into a shock front.
A star cluster forms at the shock region and the energy from the young stars dissipates the remaining gas.

Has a simulator been built that can created the star format given the stellar mass?

I thought the question is about star formation at the center of a galaxy, but the above link talks about galaxy formation itself.

Essentially, molecular clouds collapse into a ball of plasma that forms a star. I am not going to try and act like a professional astronomer, so here's a link that will have loads more information than I have. http://en.wikipedia.org/wiki/Star_formation

My understanding is that a massive black hole exists at the galactic center (spiral or elliptic) to keep the star clusters, gas and dust moving around the center. So it is not conducive for star formation, maybe otherwise.
