Applying Novel Techniques from Physical and Biological Sciences to Life Detection
Space: Science & Technology, 2023 One of the primary goals of the space exploration community is to unambiguously detect past or present life outside of Earth. As such, a number of so-called life detection technologies, instruments, and approaches have been applied as part of past ...

Nine axes of merit for technosignature searches [PDF]
International Journal of Astrobiology, 2019 AbstractIt can be difficult to develop an effective and balanced search strategy in SETI, especially from a funding perspective, given the diverse methodologies and myriad orthogonal proposals for the best technosignatures. Here I propose a framework to compare the relative advantages and disadvantages of various proposed technosignatures based on nine

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 ...

Technosignatures in the Solar System
, 2022 Abstract: NASA has five robotic space probes on escape trajectories from the solar system (Pioneer 11, Pioneer 12, Voyager 1, Voyager 2, and New Horizons), and the Interstellar Probe is a concept likely to be submitted for consideration in the forthcoming Solar & Space Physics Decadal Survey.

The Breakthrough Listen Search for Intelligent Life: Technosignature Search of 97 Nearby Galaxies
The Astronomical Journal, 2023 The Breakthrough Listen search for intelligent life is, to date, the most extensive technosignature search of nearby celestial objects. We present a radio technosignature search of the centers of 97 nearby galaxies, observed by Breakthrough Listen at the

A Novel Technosignature Search in the Breakthrough Listen Green Bank Telescope Archive
The Astronomical JournalThe Breakthrough Listen program is, to date, the most extensive search for technological life beyond Earth. Over the past 9 yr, it has surveyed thousands of nearby stars and close to 100 nearby galaxies with telescopes around the world, including the ...

Natural-Like Technosignatures and Artificial Intelligence
, 2023 Natural-like technosignatures candidates may represent a detection problem for both artificial systems and humans. We tested traditional computer vision models with natural formations with special characteristics, Ahuna Mons region in Ceres in this particular case. We looked if these artificial models may represent a trustful aid to human detection and

Technosignature Searches of Interstellar Objects
With the discovery of the third confirmed interstellar object (ISO), 3I/ATLAS, we have entered a new phase in the exploration of these long-predicted objects. Though confirmed discovery of ISOs is quite recent, their utility as targets in the search for technosignatures (historically known as the Search for Extraterrestrial Intelligence -- SETI) has ...

An Extragalactic Widefield Search for Technosignatures with the Murchison Widefield Array
The Astrophysical JournalIt is common for surveys that are designed to find artificial signals generated by distant civilizations to focus on galactic sources. Recently, researchers have started focusing on searching for all other sources within the field observed, including the
