论文摘要
我们得出了与紧凑型二进制合并S190814BV的任何电磁对应物的限制，其参数与黑洞和中子星的合并一致。我们通过新的广阔光学成像仪DDOTI进行了观察，并考虑了Palmer等人报道的Swift/BAT观察结果。 （2019）。我们表明，Swift/BAT会在98％的置信度下检测到具有与典型的轴上短GRB相似的对应物，而我们的DDOTI观察结果仅在27％的置信度下排除了这样的对应物。也没有足够的敏感性来排除诸如GW 170817之类的外轴对应物。我们比较了Swift/Bat和Ddoti的效率，以便将来观察到，并表明DDOTI的效率可能是Swift/BAT的效率大约是Off-Axis的效率大约两倍，用于离轴事件的效率约为100 mpc。
We derive limits on any electromagnetic counterpart to the compact binary merger S190814bv, whose parameters are consistent with the merger of a black hole and a neutron star. We present observations with the new wide-field optical imager DDOTI and also consider Swift/BAT observations reported by Palmer et al. (2019). We show that Swift/BAT would have detected a counterpart with similar properties to a typical on-axis short GRB at the 98 per cent confidence level, whereas our DDOTI observations only rule out such a counterpart at the 27 per cent confidence level. Neither have sufficient sensitivity to rule out an off-axis counterpart like GW 170817. We compare the efficiency of Swift/BAT and DDOTI for future observations, and show that DDOTI is likely to be about twice as efficient as Swift/BAT for off-axis events up to about 100 Mpc.
