cds-question@unistra.frexoplanetsradio-sourcesradio-astronomyThe 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 1GHz. In this survey at 110-190MHz, observations of 1631198 targets from TESS and Gaia are reported. Observations took place simultaneously with two international stations (noninterferometric) of the Low Frequency Array in Ireland and Sweden. We can reject the presence of any Doppler drifting narrowband transmissions in the barycentric frame of reference, with equivalent isotropic radiated power of 1017W, for 0.4million (or 1.3million) stellar systems at 110 (or 190)MHz. This work demonstrates the effectiveness of using multisite simultaneous observations for rejecting anthropogenic signals in the search for technosignatures.2023AJ....166..193Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/166/193CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018)J/ApJ/767/94 : 1.1-1.9GHz SETI survey of KOIs.
