论文摘要
我们在周期性快速无线电爆发（FRB）180916.J0158+65爆发的几秒钟内提出了深度的Apache点观测观测。在其预期的活动阶段的顶峰以及加拿大氢强度映射实验（Chime）的最新30分钟观察窗口中，我们没有检测到M_I = 24.7〜MAG（3-Sigma）在2.2到1938.1秒的光学频段后，我们没有检测到任何短暂的光学发射。将我们的限制幅度与在FRB 180916+J0158.65的Circumburst环境中形成的同步子Maser的模型进行比较，我们限制了爆发能量> 1e44 ERG的场景，而Circumburst密度为> 1e4 cm-3。
We present deep Apache Point Observatory optical observations within seconds of the outburst of the periodic fast radio burst (FRB) 180916.J0158+65 obtained on 3 September 2020. FRB 180916.J0158+65 is located in a nearby spiral galaxy 150 Mpc away and has an "active phase" with a well-measured period of approximately 16.3 days. Targeting the FRB at the peak of its expected active phase and during a recent 30 minute observing window by the Canadian Hydrogen Intensity Mapping Experiment (CHIME), we did not detect any transient optical emission at m_i=24.7~mag (3-sigma) from 2.2 to 1938.1 seconds after the burst arrival time in optical bands (corrected for dispersion). Comparing our limiting magnitudes to models of a synchrotron maser formed in the circumburst environment of FRB 180916+J0158.65, we constrain scenarios where the burst energy was >1e44 erg and the circumburst density was >1e4 cm-3.
