In Search of Extraterrestrial Artificial Intelligence Through Dyson Sphere–like Structures around Primordial Black Holes [PDF]

open access: greenThe Astrophysical Journal
Are we alone? It is a compelling question that human beings have confronted for centuries. The search for extraterrestrial life is a broad range of quests for finding simple forms of life up to intelligent beings in the Universe. The plausible assumption

The search for extraterrestrial intelligence: Telecommunications technology [PDF]

open access: greenIEEE Communications Society Magazine, 1980
Efforts to discover evidence of intelligent extraterrestrial life have become not only feasible, but respectable. Fledgling observational projects have begun that will use stateof-the-art hardware to develop sophisticated receiving and data processing systems. The rationale behind the Search for Extraterrestrial Intelligence (SETI), the manner in which

Signal Synchronization Strategies and Time Domain SETI with Gaia DR3

open access: yesThe Astronomical Journal, 2023
Spatiotemporal techniques for signal coordination with actively transmitting extraterrestrial civilizations, without the need for prior communication, can constrain technosignature searches to a significantly smaller coordinate space.

The Most Sensitive SETI Observations Toward Barnard's Star with FAST

open access: yesThe Astronomical Journal, 2023
Search for extraterrestrial intelligence (SETI) has been mainly focused on nearby stars and their planets in recent years. Barnard’s star is the second closest star system to the Sun and the closest star in the Five-hundred-meter Aperture Spherical radio
