Gaia-assisted SETI Ellipsoid: identifying 32 SN 1987A technosignature targets in the southern TESS continuous viewing zone
To the point
Bárbara Cabrales and colleagues propose the SETI Ellipsoid approach, which uses Gaia EDR3 distances to define an ellipsoidal region around SN 1987A and identify 32 nearby targets in the southern TESS viewing zone as potential technosignature sources so wide-field time-domain surveys can monitor for coordinated signals despite timing uncertainties over about a year.
