Tabor and Loeb forecast detectability of hypothetical artificial illumination on Proxima b. This is not a detection. The paper acknowledges an estimated instrument noise floor ten times its predicted signal.
Supplied preprint text and native layouts; conditional modelLingam and Loeb consider whether some fast radio bursts could be artificial propulsion beams. The paper presents conditional models and possible tests, explicitly treating the artificial explanation as more speculative than astrophysical alternatives.
Complete supplied v2 text and native layouts; model unreplicatedGuillochon 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 modelLin, Gonzalez Abad and Loeb model whether hypothetical industrial pollutants could be detected in an exoplanet atmosphere. Their exposure forecasts are conditional and supply no detected pollution or civilization.
Supplied preprint text and native layouts; conditional modelLoeb and Turner propose tracking brightness changes with distance to help distinguish intrinsic illumination from reflected sunlight. The model requires assumptions about luminosity, geometry, spectrum and albedo. They retain conventional variability from phase, surfaces, outgassing, rotation and binary effects, plus cloud and geometry limitations for exoplanets. Historical telescope forecasts and inconclusive null results limit the proposal. The paper reports no artificial-light detection or replicated experiment.
Complete supplied preprint text and ten native layouts; original-version gapsLingam and Loeb propose spectral edges from hypothetical extensive photovoltaic surfaces as possible technosignatures. Contrast and power estimates depend on assumed coverage, reflectivity and geometry. Vegetation, minerals, clouds and ordinary heat transport remain alternatives. The figures combine cited reflectance curves and a schematic orbital scenario. The paper reports no detected extraterrestrial arrays. Historical instrument forecasts, manuscript comments and work-level Starshot support are qualified separately.
