Advanced wavefront sensing and control demonstration with MagAO-X
Sebastiaan Y. Haffert, Jared R. Males, Kyle Van Gorkom +13
The search for exoplanets is pushing adaptive optics systems on ground-based telescopes to their limits. Currently, we are limited by two sources of noise: the temporal control err…
The Visible Integral-field Spectrograph eXtreme (VIS-X): high-resolution spectroscopy with MagAO-X
Sebastiaan Y. Haffert, Jared R. Males, Laird M. Close +9
MagAO-X system is a new adaptive optics for the Magellan Clay 6.5m telescope. MagAO-X has been designed to provide extreme adaptive optics (ExAO) performance in the visible. VIS-X…
Constraining the Orbit and Mass of epsilon Eridani b with Radial Velocities, Hipparcos IAD-Gaia DR2 Astrometry, and Multi-epoch Vortex Coronagraphy Upper Limits
Jorge Llop-Sayson, Jason J. Wang, Jean-Baptiste Ruffio +30
~Eridani is a young planetary system hosting a complex multi-belt debris disk and a confirmed Jupiter-like planet orbiting at 3.48 AU from its host star. Its age and architectur…
Exoplanet Detection in Starshade Images
Mengya, Hu, Anthony Harness +2
A starshade suppresses starlight by a factor of 1E11 in the image plane of a telescope, which is crucial for directly imaging Earth-like exoplanets. The state of the art in high co…
Data-driven subspace predictive control of adaptive optics for high-contrast imaging
Sebastiaan Y. Haffert, Jared R. Males, Laird M. Close +11
The search for exoplanets is pushing adaptive optics systems on ground-based telescopes to their limits. One of the major limitations at small angular separations, exactly where ex…
Bernoulli generalized likelihood ratio test for signal detection from photon counting images
Mengya Hu, He Sun, Anthony Harness +1
Because exoplanets are extremely dim, an Electron Multiplying Charged Coupled Device (EMCCD) operating in photon counting (PC) mode is necessary to reduce the detector noise level…
High-Contrast Integral Field Spectrograph (HCIFS): multi-spectral wavefront control and reduced-dimensional system identification
He Sun, Alexei Goun, Susan Redmond +4
Any high-contrast imaging instrument in a future large space-based telescope will include an integral field spectrograph (IFS) for measuring broadband starlight residuals and chara…
Learning a Probabilistic Strategy for Computational Imaging Sensor Selection
He Sun, Adrian V. Dalca, Katherine L. Bouman
Optimized sensing is important for computational imaging in low-resource environments, when images must be recovered from severely limited measurements. In this paper, we propose a…
Efficient wavefront sensing for space-based adaptive optics
He Sun, N. Jeremy Kasdin, Robert Vanderbei
Future large space telescopes will be equipped with adaptive optics (AO) to overcome wavefront aberrations and achieve high contrast for imaging faint astronomical objects, such as…
Identification and adaptive control of a high-contrast focal plane wavefront correction system
He Sun, N. Jeremy Kasdin, Robert Vanderbei
All coronagraphic instruments for exoplanet high-contrast imaging need wavefront correction systems to reject optical aberrations and create sufficiently dark holes. Since the most…
