Theoretical physics implications of the binary black-hole mergers GW150914 and GW151226

The recent gravitational wave observations GW150914 and GW151226 reported by the LIGO and Virgo collaborations confirmed a key prediction of general relativity (GR). In this recent Physical Review D paper, the authors ask whether these events are also compatible with a variety of modifications of GR and alternative theories of gravity. In this wide-ranging and thorough study, the authors find that the recent observations put severe constraints on these non-standard theories.
