| 英文摘要 | The ligo detection of gravitational waves (gw) from merging black holes in 2015 marked the beginning of a new era in observational astronomy. the detection of an electromagnetic signal from a gw source is the critical next step to explore in detail the physics involved. the antarctic survey telescopes (ast3), located at dome a, antarctica, is uniquely situated for rapid response time-domain astronomy with its continuous night-time coverage during the austral winter. we report optical observations of the gw source (gw 170817) in the nearby galaxy ngc 4993 using ast3. the data show a rapidly fading transient at around 1 day after the gw trigger, with the i-band magnitude declining from 17.23 +/- 0.13 magnitude to 17.72 +/- 0.09 magnitude in similar to 1.8 h. the brightness and time evolution of the optical transient associated with gw 170817 are broadly consistent with the predictions of models involving merging binary neutron stars. we infer from our data that the merging process ejected about similar to 10(-2) solar mass of radioactive material at a speed of up to 30% the speed of light.
