We adopt a cosmological model that is spatially flat with  = 0.3; H0 = 70 km/s/Mpc.

Yes. The intense wind created by the rapid expulsion of infalling matter drives away a supermassive black hole's feeding source.

As the black hole pushes away the gas, dust, and stars near it—it stops feeding and stops spitting out new material for seeding new stars. The paper in question describes the
end of the black hole's ability to seed. The end of the cycle. A black hole that has reached its size limit no longer seeds new star formation.

You'll have to explain further. The end of a black hole's feeding is by nature not a cyclic thing. It's something that stops. If you're talking about a cyclic universe (big bang / big crunch) then I don't see how you're relating this paper (which doesn't describe anything like that) to such a universe.
Please help me understand: How would you define "cyclic universe" and "cyclic process" in your own words Quote:

It would not be easy to see a black hole that sucks in matter only. It wouldn't emit anything that we could see.
