Galactic Radio Explorer: an all-sky monitor for bright radio bursts

Understand

We present the Galactic Radio Explorer (GReX), an all-sky monitor to probe the brightest bursts in the radio sky.

• Building on the success of STARE2, we will search for fast radio bursts (FRBs) emitted from Galactic magnetars as well as bursts from nearby galaxies.
• GReX will search down to ten microseconds time resolution, allowing us to find new super giant radio pulses from Milky Way pulsars and study their broadband emission.
• The proposed instrument will employ ultra-wide band (0.7-2 GHz) feeds coupled to a high performance (receiver temperature 10 K) low noise amplifier (LNA) originally developed for the DSA-110 and DSA-2000 projects.
