The FAST-SETI Milky Way Globular Cluster Survey. I. A Pilot Multibeam On-the-fly Search of Five Globular Clusters at the L Band

open access: yesThe Astronomical Journal
We report a narrowband technosignature search toward five Milky Way globular clusters—NGC 6171, NGC 6218, NGC 6254, NGC 6838, and IC 1276—using Five-hundred-meter Aperture Spherical radio Telescope (FAST)’s 19 beam L -band receiver (1.05–1.45 GHz).

An Improved Machine Learning Approach for Radio Frequency Interference Mitigation in FAST–SETI Survey Archival Data

open access: yesThe Astronomical Journal
The search for extraterrestrial intelligence (SETI) commensal surveys aim to scan the sky to detect technosignatures from extraterrestrial life. A major challenge in SETI is the effective mitigation of radio frequency interference (RFI), a critical step ...

Technosignature Searches of Interstellar Objects

open access: yes
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 ...

Detecting Extraterrestrial Civilizations that Employ an Earth-level Deep Space Network

open access: yesThe Astrophysical Journal Letters
A major aspect of the search for extraterrestrial intelligence (SETI) involves searching for electromagnetic transmissions from extraterrestrial sources, often using our own transmissions as a guide.

The Technosignature before SETI

open access: yes
The technosignature has a prehistory. Indeed, there is a history of the technosignature before SETI. And it long predates the invention of the radio telescope. Here I draw from research related to my book-in-progress, The Astrobiological Turn, to sketch a genealogy of the technosignature.

Yuti: A General-purpose Transit Simulator for Arbitrary Shaped Objects Orbiting Stars

open access: yesThe Astronomical Journal
We present a versatile transit simulator ( Yuti ) aimed at generating light curves for arbitrarily shaped objects transiting stars. Utilizing a Monte Carlo algorithm, it accurately models the stellar flux blocked by these objects, producing precise light
