Natural and Artificial Spectral Edges in Exoplanets

Manasvi Lingam, Abraham Loeb. arxiv.org. May 25, 2017.

Lingam 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.

Detection Technique for Artificially-Illuminated Objects in the Outer Solar System and Beyond

Abraham Loeb, Edwin L. Turner. arxiv.org. March 13, 2012.

Loeb 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.

The Obama administration’s startling UFO connections

Alejandro Rojas. openminds.tv. October 28, 2009.

Rojas reports a conversation with Grant Cameron and relays historical claims about presidential interest in UFOs. He also acknowledges unknown Obama interest and ordinary political connections; the reported letters, memoir account and public requests do not establish secret programme access.

Eavesdropping on Radio Broadcasts from Galactic Civilizations with Upcoming Observatories for Redshifted 21cm Radiation

Abraham Loeb, Matias Zaldarriaga. arxiv.org. November 19, 2006.

Loeb 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.

A Covert Agenda: The British Government's UFO Top Secrets Exposed

Nick Redfern. everand.com. March 1, 2004.

Pope describes his MoD duties and correspondence with Redfern, but favors bureaucracy over the author’s coverup interpretation. Redfern retells his father’s alleged 1952 radar experience through a 1978 family conversation. Other historical reports are edited quotations, with no original records received. Ordinary alternatives, uncertain timing, absent radar or film, and a failed archive search remain alongside the accounts.

UFOs and the Extraterrestrial Contact Movement, Volume One — selected chapters

George M. Eberhart. cufos.org. 1986.

Eberhart maps literature, light reports, propulsion, radar, encounters, abduction, retrieval, effects, animal and space reports. Moore/Stringfield, Cash–Landrum, Gill and government-interest stories retain attribution and unread originals. Maritime, Tunguska, lunar and early historical interpretations retain ordinary alternatives, fiction and source cautions. J. Gordon Melton signs the religious introduction; psychic hypotheses and public-belief titles are distinct from clinical findings or event proof. Editions, replies, unseen originals and poll-title numbers remain qualified. Bibliography titles establish no alien artifact, secret access or completed original study.

Selected chapters; whole bibliography remains partial
