Simulation tools for realistic high-order wavefront correction with the Roman Coronagraph
A. Lau, A. J. Riggs, S. F. Redmond +9
The Roman Space Telescope Coronagraph Instrument (Roman CGI) will demonstrate high-contrast imaging from space using coronagraphic masks, deformable mirrors, and high-order wavefro…

Enhanced wavefront sensing for the Roman Coronagraph Instrument: Gaussian probes and compact model validation
Lukas Delaye, Iva Laginja, Pierre Baudoz +10
The Coronagraph Instrument on the Roman Space Telescope will be the first space-based system to demonstrate closed-loop focal-plane wavefront sensing and control, a key step toward…

Coherence differential imaging using gradient-boosted decision trees for the direct detection of exoplanets
Johan Mazoyer, María J. Mellado-Tenorio, Axel Potier +4
Coronagraphic imaging of exoplanets is limited by residual speckles that mimic planets. Advanced post-processing is essential for current and future instruments on the ground or in…
