The Roman Coronagraph Community Participation Program: early calibration plan and pilot observation of a companion
Julien H. Girard, Eric Cady, Neil T. Zimmerman +42
Roman is set to launch in weeks! The Coronagraph Instrument - technology pathfinder for future direct imaging missions - is ready to fly too. According to predictions, laboratory t…
Demonstrating the integration of a photonic lantern with an all-fiber-based nulling interferometer
Jordan Diaz, Rebecca Jensen-Clem, Philip M. Hinz +12
High-contrast imaging of Solar System scale exoplanets and protoplanets demands advancements in instrumentation to access deeper starlight suppression at smaller angular separation…
Enhanced wavefront sensing for the Roman Coronagraph Instrument: Gaussian probes and compact model validation
Lukas Delaye, Iva Laginja, Pierre Baudoz +10
The paper evaluates the use of Gaussian probe patterns for focal‑plane wavefront sensing in the Roman Space Telescope's Coronagraph Instrument, showing via simulations that they ca…
HWO Target Stars and Systems: A Prioritized Community List of Potential Stellar Targets for the Habitable Worlds Observatory's ExoEarth Survey
Noah W. Tuchow, Caleb K. Harada, Eric E. Mamajek +9
The HWO Target Stars and Systems 2025 (TSS25) list is a community-developed catalog of potential stellar targets for the Habitable Worlds Observatory (HWO) in its survey to directl…
Demonstrating Improved Contrast on the Roman Coronagraph with Spatial Linear Dark Field Control
Thayne Currie, Olivier Guyon, Ruslan Belikov +2
The baseline contrast floor from the Roman Coronagraph's High-Order Wavefront Sensing and Control strategy likely degrades over the course of time, requiring periodic recalibration…
Flight masks of the Roman Space Telescope Coronagraph Instrument
A. J. Eldorado Riggs, Vanessa P. Bailey, Dwight Moody +25
Over the past two decades, thousands of confirmed exoplanets have been detected. The next major challenge is to characterize these other worlds and their stellar systems. Much info…
