I recall reading the first experimental paper on analog gravitational black holes being created using bose einstein condensates(http://journals.aps.org/prl/abstract/10.1103/PhysRevLett.105...), and was happy to see the work continuing here (see referenced paper in the article: http://arxiv.org/abs/1510.00621).

What was very surprising was that it was a single author paper (only the prof of the group). These sort of research efforts are usually Prof+possible postdoc+a few grad students. Not sure if prof is leaving grad students out (I hope not!), or is toiling alone at this work.
