射电阵列望远镜搜索快速RadioBursts的优化

Optimization of Radio Array Telescopes to Search for Fast RadioBursts

Jeffrey B Peterson, Kevin Bandura, Pranav Sanghavi

摘要:

我们目前预计快速射电暴检测率进行调查,使用一套假设的密集阵列望远镜。这种调查的成本效率下降的速度至少与调查频率的平方反比一样快。在0至25 $\rm{m^2}$的范围内存在最佳阵列元件有效面积。如果FRB积分源计数与注量$α= d ~ln R/d ~ln F > -1$的幂律指数,则最具成本效益的望远镜布局使用单独的偶极子元件,这提供了全天视场。如果$α<-1$培养皿阵列更具成本效益。

英文摘要:

We present projected Fast Radio Burst detection rates from surveys carried out using a set of hypothetical close-packed array telescopes. The cost efficiency of such a survey falls at least as fast as the inverse square of the survey frequency. There is an optimum array element effective area in the range 0 to 25 $\rm{m^2}$. If the power law index of the FRB integrated source count versus fluence $α= d ~ln R/d ~ln F > -1$ the most cost effective telescope layout uses individual dipole elements, which provides an all-sky field of view. If $α<-1$ dish arrays are more cost effective.
