A Covariance-Aware Framework for Spatially Resolved Exoplanet Biosignature Inference with the Solar Gravitational Lens
Slava G. Turyshev
Assessing possible life on an exoplanet requires spatial, spectral, temporal, and environmental context rather than a threshold detection of one molecule or surface feature. We dev…
Relativistic framework for high-precision GNSS processing in GCRS/BCRS with extension to cislunar space
Slava G. Turyshev, Yoaz E. Bar-Sever, William I. Bertiger
We present an implementation-oriented relativistic modeling framework for high-precision {\tt GNSS} processing consistent with the IAU-adopted Barycentric and Geocentric Celestial…
Optical Ground Stations for Space Communications:Systems Engineering, Availability, and Service Economics Through 2030
Slava G. Turyshev
Optical ground stations (OGSs) are becoming networked infrastructure for high-rate space-to-Earth communications, but their adoption is governed by service availability and utiliza…
Ultra-High-Resolution Astronomy with the Solar Gravitational Lens
Slava G. Turyshev
The solar gravitational lens (SGL) is a target-specific observatory: the Sun supplies the wave-optical element, while spacecraft provide occultation, annular photometry, sampling,…
Gravitational lensing for interstellar power transmission
Slava G. Turyshev
We investigate the propagation of monochromatic electromagnetic waves through multiple, well-separated, monopole gravitational lenses in the thin-lens/eikonal approximation. For th…
Direct High-Resolution Imaging of Earth-like Exoplanets with the Solar Gravitational Lens
Slava G. Turyshev
We present a scalar, aperture-averaged observability benchmark for resolved exoplanet imaging with the solar gravitational lens (SGL). A real Earth luminance map is propagated thro…
