The Roman Coronagraph Community Participation Program: pre-launch reference star list and impact of reference star properties on post-processing performance
Justin Hom, Schuyler G. Wolff, Jessica Gersh-Range +51
The upcoming Roman Coronagraph will be the first high-contrast instrument in space capable of high-order wavefront sensing and control technologies, a critical technology demonstra…
Comparing realtime optical gain measurement and methods on MagAO-X
Eden McEwen, Jared R. Males, Olivier Guyon +20
A lingering technical challenge for pyramid wavefront sensors (PyWFS) is their change in response between calibration and correction residuals, a quantity known as optical gain (OG…
Closed-loop Atmospheric Dispersion Correction for High-Contrast Imaging with MagAO-X
Katie Twitchell, Sebastiaan Haffert, Jared R. Males +17
Incoming starlight is refracted as it enters Earth's atmosphere from the vacuum of space. The wavelength-dependence of atmospheric refraction causes elongation of the broadband PSF…
The eXtreme Wavefront Control Toolkit: High-Contrast Imaging Instrument Control for Ground and Space-Based Coronagraphs
Jared R. Males, Joseph D. Long, Sebastiaan Y. Haffert +16
We present the eXtreme Wavefront Control Toolkit (XWCTk) instrument control software system developed for the MagAO-X extreme adaptive optics (ExAO) instrument. The XWCTk is built…
Visible-Light High-Contrast Polarimetry with MagAO-X: Characterization and Initial Results
Miles Lucas, Laird Close, Jared R. Males +22
MagAO-X is a visible-light extreme adaptive optics instrument on the 6.5 meter Magellan Clay Telescope, recently upgraded to enable high-contrast polarimetric differential imaging…
The Space Coronagraph Optical Bench (SCoOB): 11. Modeling and correction of chromatic aberrations
Kyle Van Gorkom, Ramya M. Anche, Saraswathi Kalyani Subramanian +12
The space coronagraph optical bench (SCoOB) is a high contrast imaging testbed designed to demonstrate starlight suppression techniques at visible wavelengths in a space-like vacuu…
