I had the same question! From what I can gather, the black hole is plowing through gas, when the gas gets too close to the black hole, it gets sucked in and forms a disk around the black hole. As the gas disk spirals in towards the black hole, it gets heated up and shocked, causing it to fragment and form clumps. These clumps eventually collapse under their own gravity, forming stars. How cool is that!
