Spectral Selection in Sphere-Constrained Flows Generated by Polynomials of the Dirichlet Laplacian
Javed Hussain
Let be a bounded smooth domain and let be the positive Dirichlet Laplacian on . For a real polynomial with positive leading coefficient, w…
No need to modulate: On-sky results of a Neural Network enhanced pyramid wavefront sensor and prospects for the ELTs
Rico Landman, Liam Koning, Sebastiaan Y. Haffert +20
One of the main limitations of ground-based extreme adaptive optics systems (XAO) is the balance between the temporal and photon noise error. The unmodulated Pyramid Wavefront Sens…
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…
On-sky demonstration of self-learning predictive control with MagAO-X
Sebastiaan Y. Haffert, Jared R. Males, Parker T. Johnson +13
Direct imaging of exoplanets is very tricky and requires extremely well corrected wavefronts. Especially low-order order modes are detrimental to the performance of coronagraphs at…
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…
The final design of GMagAO-X: the wavefront sensing and control (WFS&C) architecture of GMagAO-X
Sebastiaan Y. Haffert, Jared R. Males, Laird M. Close +10
The Giant Magellan Adaptive Optics eXtreme (GMagAO-X) instrument has now been selected as an official part of the Giant Magellan Telescope's (GMT) instrument suite. The instrument…
