Recently, with Jahed Abedi and Hannah Dykaar, we found gravitational wave signatures for quantum gravity effects near black hole horizons. If you’d like to hear more about this, and you’re in Waterloo, come to my seminar tomorrow:

Our original paper can be found here, with additional press coverage (in various languages):

In a second paper, which just appeared on arXiv, we clarify some of the misunderstandings about our finding.

Delayed echoes from Planck-scale structure near black hole horizons predict a peak at x=1 in this plot. As can be seen, analysis of LIGO gravitational wave data indeed shows such a peak with >99% confidence level (from arXiv:1701.03485)
