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…
The Roman Coronagraph Community Participation Program: Observation planning and data reduction for polarimetric mode
Ramya M Anche, Toshiyuki Mizuki, Justin Hom +25
Reflected-light polarimetry of exoplanets constrains and resolves degeneracies in atmospheric properties, while polarized light observations of debris disks enable the characteriza…
The Roman Coronagraph Community Participation Program: trials and triumphs of designing an observing program for a technology demonstration instrument
Schuyler G. Wolff, Vanessa P. Bailey, Justin Hom +19
The Coronagraph Instrument onboard the Nancy Grace Roman Space Telescope serves as a crucial technology pathfinder for the Habitable Worlds Observatory, with on-sky verification of…
Laboratory demonstration of low order wavefront control using light reflected off the vortex coronagraph
Clarissa R. Do Ó, Kane Sjoberg, Luke Lamitina +4
The Astro2020 Decadal Survey identified exoplanet imaging as a high priority for the Habitable Worlds Observatory (HWO), which must image and characterize exo-Earths at contrasts o…
CATKit2-HCI: a collaborative framework for advancing high-contrast coronagraph testbeds
Rémi Soummer, Iva Laginja, Emiel H. Por +19
High-contrast exoplanet imaging requires dedicated laboratory testbeds for the development and validation of coronagraph architectures, wavefront sensing and control methods, calib…
