Breakthrough Listen Search for Technosignatures toward the Kepler-160 System

We have conducted a search for artificial radio emission associated with the Kepler-160 system following the report of the discovery of the Earth-like planet candidate KOI-456.04 on 2020 June 4 (Heller et al. 2020). Our search targeted both narrowband (2.97 Hz) drifting (±4 Hz s^-1) and wideband pulsed (5 ms at all bandwidths) artificially dispersed technosignatures using the turboSETI (Enriquez et al. 2017) and SPANDAK (V. Gajjar et al. 2020, in preparation) pipelines, respectively, from 1 to 8 GHz. No candidates were identified above an upper limit Equivalent Isotropic Radiated Power of 5.9 × 10¹⁴ W for narrowband emission and 7.3 × 10¹² W for wideband emission. Here we briefly describe our observations and data reduction procedure.
