Rhonda Morgan, 2023, "ExEP Exo-Earth yield of a 6 m space telescope in the near-infrared SPIE Proceedings Paper", https://doi.org/10.48577/jpl.FBL4HC, SPIE Optics and Photonics 2023, JPL Open Repository
The search for biosignatures with the future Habitable Worlds Observatory requires high quality spectra over a broad wavelength range and of sufficient signal-to-noise. In this paper, we extend previous exoplanet yields to include wavelengths from 200 nm to 2 microns. Because the... |

Alex Walter, 2023, "Status of NASA’s stellar astrometry testbeds for exoplanet detection: Science and technology overview", https://doi.org/10.48577/jpl.TJPBFG, SPIE Optics and Photonics 2023, JPL Open Repository
Accurate measurement of exoplanetary masses is a critical step in addressing key aspects of NASA’s science vision. Measuring masses of Earth-analogs around FGK stars out to 10 pc requires sub-microarcsecond astrometric accuracy, which is not within the capabilities of current ins... |

Marie Levine-West, 2023, "Integrated Modeling of the James Webb Space Telescope: pre-Launch Predictions,Flight Performance and Lessons Learned", https://doi.org/10.48577/jpl.RPZK6Z, SPIE Optics and Photonics 2023, JPL Open Repository
Because of its size and complexity, the Observatory performance of the James Webb Space Telescope (JWST) in its operating condition was primarily verified by analysis prior to launch, breaking the standard NASA paradigm of test-as-you-fly. Most of the requisite analytical predict... |

David Marx, 2023, "Evaluation of Phase Retrieval for the Roman Space Telescope Coronagraph Instrument", https://doi.org/10.48577/jpl.XAHZGB, Optica Imaging Congress, JPL Open Repository
The Roman Space Telescope Coronagraph Instrument uses phase retrieval for instrument multiple calibrations. We describe the how phase retrieval is performed, and evaluate estimation error in the presence of instrument non-idealities. |
