Forward modelling coronagraphic images with a fully physical, differentiable digital twin of MagAO-X: first laboratory results
Matthijs Mars, Sebastiaan Y. Haffert, Louis Desdoigts +10
Post-processing of high contrast imaging data relies on an accurate model of the stellar point spread function (PSF). Current techniques build this model from the science images th…
Digging dark holes on-sky with the Self-Coherent Camera: Preliminary results
Elena Tonucci, Sebastiaan Y. Haffert, Jared R. Males +17
Current high-contrast imaging instruments are limited by wavefront errors originating from non-common path aberrations (NCPAs) due, for example, to manufacturing errors in the opti…
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…
Quantum-optimal instruments for high-contrast imaging with multi-plane light converters
Sebastiaan Y. Haffert, Yinzi Xin, Rico Landman
Spatial Mode Demultiplexers (SPADE) are devices that split an incoming wavefront into a particular set of electric field modes. SPADEs have been shown to be quantum-optimal for man…
Demonstration of simultaneous PIAA- coronagraphy and wavefront sensing using a single metasurface-based focal-plane optic
Dhwanil Patel, Sebastiaan Y. Haffert, Skyler Palatnick +23
Controlling residual wavefront aberrations downstream of an extreme adaptive optics (ExAO) system is a major challenge in high-contrast imaging. These aberrations produce quasi-sta…
Exposure-averaged Gaussian Processes for Combining Overlapping Datasets
Jacob K. Luhn, Ryan A. Rubenzahl, Samuel Halverson +1
Physically motivated Gaussian process (GP) kernels for stellar variability, like the commonly used damped, driven simple harmonic oscillators that model stellar granulation and p-m…
