Millimetre/Sub-Millimetre SETI: Expanding The Radio Technosignature Parameter Space With ALMA2040
[astro-ph.IM] The search for extraterrestrial intelligence (SETI) has been largely concentrated at centimetre wavelengths, and in particular in the ‘water hole’ (1.42-1.66 GHz) range. The millimetre and sub-millimetre sky is, […]

Beyond The Beacon: State And Corporate Competition After An Information-Rich Technosignature Detection
[astro-ph.IM] The 2026 update to the Declaration of Principles Concerning the Conduct of the Search for Extraterrestrial Intelligence provides a framework for post-detection practice.
![Grad-CAM autopsy at an amplitude of 4.0. (a) Q2_bright_hit: D1-3 S-shaped, detected. (b) Q2c_bright_mis: D1-1 extreme drift, missed. Columns: input, Grad-CAM map, and CAM difference (injected minus clean). Inputs are shown as the detector sees them: the three ON panels side by side, with frequency running vertically; white lines mark panel boundaries and the green line the injection’s starting channel. -- [astro-ph.IM]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/10/Missed-Detections.png?resize=1200%2C720&ssl=1)
