Solar System Surface Technosignatures: Searching for Signs of Artificial Design on Extraterrestrial Terrain
Ana Henrique, Sofia Sheikh, Benjamin Fields
Artificial radio emissions have historically been a major focus of technosignature searches. Here, we apply an anthropological lens to expand this scope to surface technosignatures…
Opportunity Lost in Searching for Technosignatures
Steve Prabu, David DeBoer, Andrew Siemion +6
The sensitivity of radio technosignature searches has improved dramatically over the last five decades; however, as the RFI environment from which these searches are conducted has…
Searching for Extraterrestrial Intelligence with the SKA
Chenoa D. Tremblay, Alex Andersson, Joe Bright +19
The search for technosignatures (also known as the Search for Extraterrestrial Intelligence or SETI) depends critically on our ability to distinguish artificial signals from the ri…
Technosignature Searches of Interstellar Objects
James R. A. Davenport, Sofia Z. Sheikh, Steve Croft +17
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 disc…
Earth Detecting Earth: At what distance could Earth's constellation of technosignatures be detected with present-day technology?
Sofia Z. Sheikh, Macy J. Huston, Pinchen Fan +5
The field of the Search for Extraterrestrial Intelligence (SETI) searches for ``technosignatures'' that could provide the first detection of life beyond Earth through the technolog…
COSMIC's Large-Scale Search for Technosignatures during the VLA sky Survey: Survey Description and First Results
Chenoa D. Tremblay, Jared Sofair, Lucy Steffes +9
Developing algorithms to search through data efficiently is a challenging part of searching for signs of technology beyond our solar system. We have built a digital signal processi…
Searching the SN 1987A SETI Ellipsoid with TESS
Bárbara Cabrales, James R. A. Davenport, Sofia Z. Sheikh +4
The SETI Ellipsoid is a strategy for technosignature candidate selection which assumes that extraterrestrial civilizations who have observed a galactic-scale event -- such as super…
The Breakthrough Listen Search for Intelligent Life: Technosignature Search of 97 Nearby Galaxies
Carmen Choza, Daniel Bautista, Steve Croft +18
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…
Data-Driven Approaches to Searches for the Technosignatures of Advanced Civilizations
T. Joseph W. Lazio, S. G. Djorgovski, Andrew Howard +19
Humanity has wondered whether we are alone for millennia. The discovery of life elsewhere in the Universe, particularly intelligent life, would have profound effects, comparable to…
On Detecting Interstellar Scintillation in Narrowband Radio SETI
Bryan Brzycki, Andrew P. V. Siemion, Imke de Pater +4
To date, the search for radio technosignatures has focused on sky location as a primary discriminant between technosignature candidates and anthropogenic radio frequency interferen…
Real-Time Technosignature Strategies with SN 2023ixf
James R. A. Davenport, Sofia Z. Sheikh, Wael Farah +5
Several technosignature techniques focus on historic events such as SN 1987A as the basis to search for coordinated signal broadcasts from extraterrestrial agents. The recently dis…
A 4-8 GHz Galactic Center Search for Periodic Technosignatures
Akshay Suresh, Vishal Gajjar, Pranav Nagarajan +6
Radio searches for extraterrestrial intelligence have mainly targeted the discovery of narrowband continuous-wave beacons and artificially dispersed broadband bursts. Periodic puls…
A deep-learning search for technosignatures of 820 nearby stars
Peter Xiangyuan Ma, Cherry Ng, Leandro Rizk +14
The goal of the Search for Extraterrestrial Intelligence (SETI) is to quantify the prevalence of technological life beyond Earth via their "technosignatures". One theorized technos…
A Search for Radio Technosignatures at the Solar Gravitational Lens Targeting Alpha Centauri
Nick Tusay, Macy J. Huston, Cayla M. Dedrick +17
Stars provide an enormous gain for interstellar communications at their gravitational focus, perhaps as part of an interstellar network. If the Sun is part of such a network, there…
Searching the SETI Ellipsoid with Gaia
James R. A. Davenport, Barbara Cabrales, Sofia Sheikh +4
The SETI Ellipsoid is a geometric method for prioritizing technosignature observations based on the strategy of receiving signals synchronized to conspicuous astronomical events. P…
Setigen: Simulating Radio Technosignatures for SETI
Bryan Brzycki, Andrew P. V. Siemion, Imke de Pater +6
The goal of the search for extraterrestrial intelligence (SETI) is the detection of non-human technosignatures, such as technology-produced emission in radio observations. While ma…
Opportunities for Technosignature Science in the Astro2020 Report
Jacob Haqq-Misra, Sofia Sheikh, Manasvi Lingam +7
The Astro2020 report outlines numerous recommendations that could significantly advance technosignature science. Technosignatures refer to any observable manifestations of extrater…
