In Titan’s nitrogen-methane atmosphere, photochemistry leads to the production of complex organic particles, forming Titan’s thick haze layers. Laboratory-produced aerosol analogs, or “tholins”, are produced in a number of laboratories; […]

Characterization Of An Instrument Model For Exoplanet Transit Spectrum Estimation through Wide Scale Analysis on HST Data
Instrument models (IMs) enable the reduction of systematic error in transit spectroscopy light curve data, but, since the model formulation can influence the estimation of science model parameters, characterization of […]

From Direct Measurement Of The Universe's Expansion History To Characterization Of Nearby Habitable Planet Candidates
The direct measurement of the Universe’s expansion history and the search for terrestrial planets in habitable zones around solar-type stars require extremely high-precision radial velocity measures over a decade. This […]

Stellar Gravitational Lens Engineering for Interstellar Communication and Artifact SETI
Several recent works have proposed “stellar relay” transmission systems in which a spacecraft at the focus of a star’s gravitational lens achieves dramatic boosts in the gain of an outgoing […]
