Sub-diffraction-limited coronagraphic imaging with nano-printed PIAACMC phase masks

Elena Tonucci, Sebastiaan Y. Haffert, Warren B. Foster +22

Imaging Earth-like exoplanets in the habitable zone of their host star is among the main science objectives of future ground-based and space-based observatories. However, the extre…

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…

windsoCC: reconstructing the wind-driven halo in MagAO-X images using wavefront sensor telemetry

Jay K. Kueny, Jared R. Males, Alycia J. Weinberger +16

The wind-driven halo (WDH) is a persistent, low spatial frequency noise artifact that arises due to the servo-lag error inherent to all adaptive optics (AO) instruments. Spatial fi…

ffortissimo: A Freeform Forward-Modeling Pipeline for High-Contrast Images of Circumstellar Disks Based on Automatic Differentiation

Jay K. Kueny, Joseph D. Long, Jared R. Males +16

Modeling circumstellar disks in the traditional sense carries the assumption that the dust density distribution can be accurately described with a fixed parametric form. Furthermor…
