A High-Likelihood Polar Interstellar Meteor Candidate
Richard Cloete, Abraham Loeb
We report a newly identified polar interstellar meteor candidate, labeled polarIM, detected on 2026-04-01 02:13:14 UTC at latitude , longitude , and altit…
Two Robust Interstellar Meteor Candidates in the Post-2018 CNEOS Fireball Database
Richard Cloete, Abraham Loeb
We report the identification of two previously unrecognized interstellar meteor candidates in the NASA CNEOS fireball database. Using the empirically calibrated low-discrepancy unc…
Upper Limit on the Non-Gravitational Acceleration and Lower Limits on the Nucleus Mass and Diameter of 3I/ATLAS
Richard Cloete, Abraham Loeb, Peter Vereš
We use astrometric data on 3I/ATLAS compiled by the Minor Planet Center from May 15 to September 23, 2025, and derive an upper limit on any statistically significant deviation from…
Improving the discovery of near-Earth objects with machine-learning methods
Peter Vereš, Richard Cloete, Matthew J. Payne +1
We present a comprehensive analysis of the digest2 parameters for candidates of the Near-Earth Object Confirmation Page (NEOCP) that were reported between 2019 and 2024. Our study…
Is the "Dark Comet" 2005 VL1 the Venera 2 Spacecraft?
Abraham Loeb, Richard Cloete
Recently, Seligman et. al. (2024) identified a population of near-Earth objects (NEOs) that exhibit statistically significant non-gravitational accelerations with no coma, and labe…
Commissioning An All-Sky Infrared Camera Array for Detection Of Airborne Objects
Laura Dominé, Ankit Biswas, Richard Cloete +13
To date there is little publicly available scientific data on Unidentified Aerial Phenomena (UAP) whose properties and kinematics purportedly reside outside the performance envelop…
