Fell and Loeb model radiation from an assumed zero-ADM-mass warp-bubble geometry in an atmosphere. Their relativistic aircraft-scale examples predict strong emission. The geometry-generating source and backreaction are omitted; heating, continuum validity and propagation introduce further limits. These conditional predictions constrain an interpretation, without detecting or demonstrating a drive.
Oem Trivedi, Abraham Loeb. arxiv.org. January 29, 2026.
Trivedi and Loeb propose a network for discovering and characterizing interstellar objects. Their hypothetical examples and performance estimates are conditional; the paper demonstrates no deployed network, artificial object or government programme access.
■ Supplied preprint text and native layouts; proposal remains unvalidated
Loeb models a population mass budget for 3I/ATLAS and offers ordinary cometary-core or rarer-population alternatives. Technological design is conditional speculation; albedo, size, selection and reservoir assumptions remain explicit, with no artificial-origin detection or independent model validation.

Diptajyoti Mukherjee, Amir Siraj, Hy Trac, Abraham Loeb. arxiv.org. August 7, 2023.
Mukherjee, Siraj, Trac and Loeb simulate capture and retention of interstellar objects near Earth, then estimate populations and survey detectability under assumed incoming velocities, abundance, sizes and lifetimes. The manuscript identifies no actual captured interstellar object.

Thiem Hoang, Abraham Loeb. arxiv.org. March 24, 2023.
Hoang and Loeb argue that evaporative cooling changes a trapped-hydrogen explanation for ’Oumuamua’s acceleration. The critique depends on selected thermal assumptions and does not establish an artificial origin.
Abraham (Avi) Loeb, Frank H. Laukien. galileo.hsites.harvard.edu. February 13, 2023.
Loeb and Laukien outline instrument-based investigations of aerial phenomena, interstellar objects and meteor fragments. The paper describes a research programme and proposed methods, rather than a confirmed anomalous discovery.

Siraj, Loeb and colleagues outline requirements for a proposed interstellar-object intercept. Detection and reachability forecasts depend on assumptions; material analogues and modelled spectra do not identify an artificial object.
Loeb argues that assumed high atmospheric speeds should produce strong frictional luminosity, and that a shorter inferred range could permit ordinary explanations. His conditional critique supplies no raw-observation refit or identified object. The paper acknowledges Galileo Project support and a Breakthrough Prize Foundation grant; it does not document the unnamed official visit separately reported in his book.

Amir Siraj, Abraham Loeb. arxiv.org. September 20, 2022.
Siraj and Loeb infer unusually high breakup pressures for two reported meteors from catalogue inputs. IM1 reuses the earlier analysis; IM2 remains a candidate whose interstellar origin requires confirmation. Breakup pressure is a model proxy, rather than a laboratory composition measurement. Early weak flaring, corrected light-curve normalization, sensor bias and small-number population assumptions qualify the conclusions. This paper supplies no new government approach or classified-data receipt.

Vo Hong Minh Phan, Thiem Hoang, Abraham Loeb. arxiv.org. October 28, 2021.
Phan, Hoang and Loeb model erosion and modification of icy interstellar objects under assumed cosmic-ray, material and travel conditions. Prior observations and fits support theoretical predictions rather than new detections or demonstrated composition.
■ Complete supplied seven-page manuscript; conditional erosion model
Amir Siraj, Abraham Loeb. arxiv.org. October 15, 2021.
Siraj and Loeb assess whether nitrogen-ice fragments could account for the earlier Oumuamua detection. Their conclusion depends on population and mass-budget assumptions; no new data are generated or analyzed.

Amir Siraj, Abraham Loeb. arxiv.org. July 22, 2021.
Siraj and Loeb infer a potentially large interstellar population from prior observations and population assumptions. The paper introduces no new data; selection, size distributions and model sensitivity limit its abundance estimates.
