Breakthrough Listen Search for Technosignatures Towards the Kepler-160 System

TL;DR

This study conducted a comprehensive search for artificial radio signals from the Kepler-160 system using advanced pipelines, but found no technosignatures above the specified power limits, providing constraints on potential extraterrestrial emissions.

Contribution

First systematic search for technosignatures towards Kepler-160 using both narrowband and wideband radio observations with detailed data analysis pipelines.

Findings

No technosignatures detected above the power limits

Established upper limits for potential extraterrestrial radio emissions

Demonstrated effective data reduction and analysis methods

Abstract

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 (arXiv:1905.09038v2). Our search targeted both narrowband (2.97 Hz) drifting ($\pm 4$ Hz s$^{-1})$ and wideband pulsed (5 ms at all bandwidths) artificially-dispersed technosignatures using the turboSETI (arXiv:1709.03491v2) and SPANDAK pipelines, respectively, from 1-8 GHz. No candidates were identified above an upper limit Equivalent Isotropic Radiated Power (EIRP) of $5.9 \times 10^{14}$ W for narrowband emission and $7.3 \times 10^{12}$ W for wideband emission. Here we briefly describe our observations and data reduction procedure.
