Search for Extraterrestrial Intelligence (SETI) by fractal universe
Results in Physics, 2019 We propose the hypothesis that the universes we live are provided with fractal properties, from macro to micro scale, which have self-similarity and space filling.

Undetected Past Contacts with Technological Species: Implications for Technosignature Science
The Astronomical JournalIn the search for extraterrestrial intelligence (SETI), the highly incomplete sampling of the technosignature search space is often considered as a plausible explanation for the persistent lack of detections over six decades of searches. If correct, this

Developing a Drift Rate Distribution for Technosignature Searches of Exoplanets
The Astronomical Journal, 2023 A stable-frequency transmitter with relative radial acceleration to a receiver will show a change in received frequency over time, known as a “drift rate.” For a transmission from an exoplanet, we must account for multiple components of drift rate: the ...
