论文摘要
短期无线电瞬态相空间有几个未开发的区域。这样一个未开发的区域是巨型脉冲（来自脉冲星）和宇宙学位置的快速无线电爆发（FRB）之间的光度差距。瞬态天文无线电发射2（Stare2）的调查是对此类瞬态的搜索到7 MPC。 Stare2的视野为3.6个Steradians，并且对$ \ sim300 $ kjy的一毫秒瞬态敏感。使用两个站系统，我们已经检测到并定位了太阳爆发，证明了试验系统能够检测到持续时间短的无线电瞬变。我们发现在200天的观察中，持续时间在65美元$ $ s和34毫秒之间没有令人信服的瞬态，并以95％的信心限制了$ \ sim300 $ kjy的全天空瞬变速率，$ \ sim300 $ kjy至$ <40 $ {\ rm {\ rm sky^{ - 1} ear^earl^{ - 1}} $。如果可以将FRB的光度函数推到300 kJy，距离为10 kpc，那么人们期望速率为$ \ sim2 $ $ {\ rm sky^{ - 1}年^ear^{ - 1}} $。
There are several unexplored regions of the short-duration radio transient phase space. One such unexplored region is the luminosity gap between giant pulses (from pulsars) and cosmologically located fast radio bursts (FRBs). The Survey for Transient Astronomical Radio Emission 2 (STARE2) is a search for such transients out to 7 Mpc. STARE2 has a field of view of 3.6 steradians and is sensitive to one-millisecond transients above $\sim300$ kJy. With a two-station system we have detected and localized a solar burst, demonstrating that the pilot system is capable of detecting short duration radio transients. We found no convincing transients with duration between 65 $μ$s and 34 ms in 200 days of observing, limiting with 95% confidence the all-sky rate of transients above $\sim300$ kJy to $< 40$ ${\rm sky^{-1} year^{-1}}$. If the luminosity function of FRBs could be extrapolated down to 300 kJy for a distance of 10 kpc, then one would expect the rate to be $\sim2$ ${\rm sky^{-1} year^{-1}}$.
