This paper http://arxiv.org/abs/1504.00263, Assessing inflow rates in atomic cooling halos: implications for direct collapse black holes, discusses formation of direct collapse black holes in the early universe. Supermassive black holes are the only reasonable explanation for quasers in the high z universe. A long standing question has been how can black holes achieve such staggering masses in such a short time after the BB? It is believed some SMBH could have been seeded via direct collapse, but, it has also been thought the UV background would suppress their numbers well below those necessary to explain high z quasar populations. The authors appear to have found this is not necessarily the case.
