Highest Frequency Detection of FRB 121102 at 4โ€“8 GHz Using the Breakthrough Listen Digital Backend at the Green Bank Telescope

We report the first detections of the repeating fast radio burst source FRB 121102 above 5.2 GHz. Observations were performed using the 4$-$8 GHz receiver of the Robert C. Byrd Green Bank Telescope with the Breakthrough Listen digital backend. We present the spectral, temporal and polarization properties of 21 bursts โ€ฆ
