The Roman Coronagraph Community Participation Program: calibration strategy for the Mueller matrix using on-sky sources
Toshiyuki Mizuki, Justin Hom, Bertrand Mennesson +14
The Nancy Grace Roman Space Telescope Coronagraph Instrument will provide space-based polarimetric observations of circumstellar disks and exoplanetary systems. Accurate reconstruc…
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…
Early Exploration of the Scientific Discovery Space for the Habitable Worlds Observatory
Courtney D. Dressing, Danica Adams, Evelyne Alecian +324
The paper summarizes 70 science cases for the proposed NASA Habitable Worlds Observatory, outlining the observational needs across four scientific pillars and detailing required ca…
Characterizing Earth analogs may require a moderate or high-resolution spectrograph
Jean-Baptiste Ruffio, Sarah Steiger, Corey Spohn +16
A primary goal of the Habitable Worlds Observatory (HWO) is to detect and measure the abundance of biosignature molecules, such as water (H2O) and oxygen (O2), in the atmosphere of…
Dimpled scalar vortex coronagraph laboratory demonstration
Niyati Desai, Garreth Ruane, Susan Redmond +3
Achieving the Habitable Worlds Observatory (HWO) goal of 10^-10 contrast at a separation of 3 /D across a 20% bandwidth requires coronagraph focal plane masks with both broadba…
