STARE2: Detecting Fast Radio Bursts in the Milky Way

Abstract

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 $\sim 300$ 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 $\mu$s and 34 ms in 200 days of observing, limiting with 95% confidence the all-sky rate of transients above $\sim 300$ kJy to $<40$ $\mathrm{sk}{\mathrm{y}}^{-1}\mathrm{yea}{\mathrm{r}}^{-1}$. 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 $\sim 2$ $\mathrm{sk}{\mathrm{y}}^{-1}\mathrm{yea}{\mathrm{r}}^{-1}$.
