Abstract:
The Search for Extraterrestrial Intelligence aims to find evidence of technosignatures, which can point toward the possible existence of technologically advanced extraterrestrial life. Radio signals similar to those engineered on Earth may be transmitted by other civilizations, motivating technosignature searches across the entire radio spectrum. In this endeavor, the low-frequency radio band has remained largely unexplored; with prior radio searches primarily above 1 GHz. In this presentation we discuss the results of a recent low-frequency survey of over 1,600,000 stars in our Galaxy with LOFAR (110 – 190 MHz), the expansion of SETI searches to NenuFAR (10 – 85 MHz) and the future observation plans for technosignatures at low frequencies.
