Optical SETI Observations of the Anomalous Star KIC 8462852

, 2015
To explore the hypothesis that KIC 8462852's aperiodic dimming is caused by artificial megastructures in orbit (Wright et al. 2015), rather than a natural cause such as cometary fragments in a highly elliptical orbit (Marengo et al.

Anomaly Detection and Radio-frequency Interference Classification with Unsupervised Learning in Narrowband Radio Technosignature Searches

The Astronomical Journal
The search for radio technosignatures is an anomaly detection problem: Candidate signals represent needles of interest in the proverbial haystack of radio-frequency interference (RFI). Current search frameworks find an enormity of false-positive signals,

A Radio Technosignature Search of TRAPPIST-1 with the Allen Telescope Array

The Astronomical Journal
Planet–planet occultations (PPOs) occur when one exoplanet occults another exoplanet in the same system, as seen from the Earth’s vantage point. PPOs may provide a unique opportunity to observe radio “spillover” from extraterrestrial intelligences’ radio
