  • Sixth Announced Gravitational Wave Detection, GW 170608 (16 Nov 2017)
    The LIGO Scientific and Virgo collaborations report the detection of yet another gravitational wave signal, dubbed GW 170608, emitted during the final moments of the merger of two black holes with masses of about 7 and 12 times the mass of the sun located at a redshift of ~0.07 (340 Mpc). This is one of the first cases where black holes detected through gravitational waves have masses similar to those detected indirectly via e-m radiation, such as X-rays The discovery paper was just submitted to ApJL.
