    Wow! Interesting, even it is not a "real" horizon

    That's pretty cool.

    Anyone have an opinion on how well this parallels astrophysical Hawking radiation?

    As far as I can see, the measured spectrum does not have a thermal distribution, while true Hawking radiation should.
    From their analysis, it is not clear at all (at least to me) that observed radiation is really the Hawking radiation.

    The arXiv blog has a post about it http://www.technologyreview.com/blog/arxiv/25805/

    The subsequent comments aren't particularly enlightening but are mildly amusing (particularly the one that suggests curtains satisfy the definition of a "white hole" :) )

    This ref

    http://arxiv.org/abs/1003.4150" [Broken]

    contains more details on how the physics of these systems is similar to that of a BH event horizon.

    Seems much more interesting than the experimental paper we discussed so far. Thanks!
