Radiative Signatures from Warp Drives Traveling Through the Earth's Atmosphere

Shaun David Brocus Fell, Abraham Loeb. arxiv.org. August 11, 2026.

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.

Close Encounters of the Interstellar Kind: Examining the Capture of Interstellar Objects in Near Earth Orbit

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.

Complete supplied fourteen-page manuscript; conditional capture model

Overview of the Galileo Project

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.

Physical Considerations for an Intercept Mission to a 1I/'Oumuamua-like Interstellar Object

Amir Siraj, Abraham Loeb, Amaya Moro-Martin, Mark Elowitz, Abigail White, Wesley A. Watters, Gary J. Melnick, Richard Cloete, Jonathan Grindlay, Frank Laukien. arxiv.org. November 3, 2022.

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.

"Down to Earth" Limits on Unidentified Aerial Phenomena in Ukraine (Comment on arXiv:2208.11215)

Abraham Loeb. arxiv.org. October 5, 2022.

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.

Erosion of Icy Interstellar Objects by Cosmic Rays and Implications for ‘Oumuamua

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
PaperS7745

The Mass Budget Necessary to Explain ‘Oumuamua as a Nitrogen Iceberg

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.

Complete supplied three-page manuscript; conditional mass-budget model
PaperS7744

Interstellar Objects Outnumber Solar System Objects in the Oort Cloud

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.

Complete supplied four-page manuscript; conditional abundance model
PaperS7750

Destruction of molecular hydrogen ice and Implications for 1I/2017 U1 (`Oumuamua)

Thiem Hoang, Abraham Loeb. arxiv.org. August 12, 2020.

Hoang and Loeb model destruction and formation of pure hydrogen ice under assumed radiation, material and cloud conditions. They challenge one proposed explanation of Oumuamua while retaining environmental exceptions; no hydrogen object is observed and no artificial origin is established.

Complete supplied eight-page manuscript; conditional hydrogen-ice model
PaperS7742

Fast radio bursts: the observational case for a Galactic origin

Dan Maoz, Abraham Loeb, Yossi Shvartzvald, Monika Sitek, Michael Engel, Flavien Kiefer, Marcin Kiraga, Amir Levi, Tsevi Mazeh, Michał Pawlak, R. Michael Rich, Lev Tal-Or, Lukasz Wyrzykowski. arxiv.org. September 8, 2015.

Maoz, Loeb and colleagues compare optical variability with historical radio-burst fields and propose stellar counterparts. Their association calculations depend on selection and assumptions; simultaneous counterpart evidence and raw-data replication are missing.

SETI via Leakage from Light Sails in Exoplanetary Systems

James Guillochon, Abraham Loeb. arxiv.org. September 3, 2015.

Guillochon and Loeb model possible leakage from hypothetical light-sail propulsion systems. Simulated observing windows depend on assumed inhabited systems and operating choices; the paper supplies no detection or deployed apparatus.

Complete supplied v2 text and native layouts; conditional model
PaperS7724

The 2019 Discovery of a Meteor of Interstellar Origin

Amir Siraj, Abraham Loeb. arxiv.org. April 15, 2019.

Siraj and Loeb infer an interstellar meteor trajectory from catalogue inputs and an assumed error model. The paper attributes uncertainty information to Heavner and quotes a reported DoD statement, with Worden, Daniels, Shaw, Mozer, an anonymous analyst and Hurd credited for distinct clarification roles. Original correspondence and classified data were not received. Conditional confidence, ordinary bound comparators, population assumptions and mass-budget tension remain. Government review does not establish researcher classified access, artificial origin or recovered material.
