Constraining the topological Gauss-Bonnet coupling from GW150914

Abstract

Recent gravitational wave observation based on the data from GW150914 has confirmed Hawking's area theorem and estimated the increase in total horizon area during a merger process of two Kerr black holes. We use this result and the validity of the second law to obtain the first observational bound on the 4D topological Gauss-Bonnet coupling as $\gamma \lesssim 2.804_{-1.169}^{+7.946}\times 10^9{m}^2$ with $95\%$ credibility.

arXiv commentTitle and figure changed, table added. Manuscript has been modified to match the published version in Physical Review D as a Letter. Main results of the paper remains the same, although presentation has improved
