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 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 Zaldarriaga forecast searches for accidental radio leakage with then-proposed astronomical observatories. Detectability depends on bandwidth, observing time, beam direction, duty cycle and interference. The figure and table share historical Earth-emission assumptions. Proposed orbital and habitability inferences were not performed measurements. A hypothetical relay-station private communication is attributed but unavailable. The paper reports no extraterrestrial detection; named funding is distinguished by recipient.
All eight supplied preprint pages and native layouts; journal and original-data 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.
All five supplied preprint pages and native layouts; conditional proposal and original gapsLoeb 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.
