On-sky dark hole diggin' with implicit Electric Field Conjugation on MagAO-X
S. Y. Haffert, J. Liberman, J. R. Males +17
Direct spectroscopy is very promising approach to characterizing the atmospheres of nearby rocky exoplanets. Non-common path aberrations (NCPA) are differential aberrations between…
A Multiband Study of the HR 4796A Disk in the Optical Using MagAO-X
Jay K. Kueny, Alycia J. Weinberger, Zhe-Yu Daniel Lin +18
We present total intensity images of the debris disk around HR 4796A from observations spanning 2023 to 2025 with the Magellan extreme adaptive optics instrument (MagAO-X). We dete…
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…
Phase-Induced Amplitude Apodization Complex Mask Coronagraph (PIAACMC) on-sky demonstration with MagAO-X
Elena Tonucci, Sebastiaan Haffert, Warren Foster +18
Advancing the technological development of small inner working angle (IWA) coronagraphs is essential to enabling high-contrast imaging of temperate exoplanets with future extremely…
Making the unmodulated pyramid wavefront sensor smart II. First on-sky demonstration of extreme adaptive optics with deep learning
R. Landman, S. Y. Haffert, J. D. Long +17
Pyramid wavefront sensors (PWFSs) are the preferred choice for current and future extreme adaptive optics (XAO) systems. Almost all instruments use the PWFS in its modulated form t…
