SETIBURST: A Robotic, Commensal, Realtime Multi-Science Backend for the Arecibo Telescope
Radio astronomy has traditionally depended on observatories allocating time to observers for exclusive use of their telescopes. The disadvantage of this scheme is that the data thus collected is rarely […]

Sub-milli-Kelvin Instruments – Radial Velocity Measurements: Tests with the Habitable-zone Planet Finder
Insufficient instrument thermo-mechanical stability is one of the many roadblocks for achieving 10cm/s Doppler radial velocity (RV) precision, the precision needed to detect Earth-twins orbiting Solar-type stars. Highly temperature and […]

Acoustic Properties of Glacial ice for Neutrino Detection and the Enceladus Explorer
Ultra high energy neutrinos may be observed in ice by the emission of acoustic signals. The SPATS detector has investigated the possibility of observing GZK-neutrinos in the clear ice near […]

SETI via Leakage from Light Sails in Exoplanetary Systems
The primary challenge of rocket propulsion is the burden of needing to accelerate the spacecraft’s own fuel, resulting in only a logarithmic gain in maximum speed as propellant is added […]
