Hibberd – “Is the Interstellar Object 3I/ATLAS Alien Technology?” (arXiv)
Dark-forest style thought-experiment; not Loeb, but engages with that hypothesis from another angle.
https://arxiv.org/abs/2507.12213 ([arXiv][16])
1. Official / “boring but solid” info (no Loeb)
2. Peer-reviewed papers & preprints (non-Loeb authors)
Discovery & basic physical properties
Activity, dust & gas
Origin, age & galactic context
Direct responses to the “alien probe” angle (non-Loeb)
3. JWST / SPHEREx / multi-telescope coverage
4. Popular-science articles pushing back on the alien-mothership stuff
5. Imagery, observing & amateur work
