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…
Unlocking starlight subtraction in full data rate exoplanet imaging by efficiently updating Karhunen-Loève eigenimages
Joseph D. Long, Jared R. Males
Starlight subtraction algorithms based on the method of Karhunen-Loève eigenimages have proved invaluable to exoplanet direct imaging. However, they scale poorly in runtime when pa…
The hunt for Sirius Ab: Comparison of algorithmic sky and PSF estimation performance in deep coronagraphic thermal-IR high contrast imaging
Joseph D. Long, Jared R. Males, Katie M. Morzinski +7
Despite promising astrometric signals, to date there has been no success in direct imaging of a hypothesized third member of the Sirius system. Using the Clio instrument and MagAO…
Design of the MagAO-X Pyramid Wavefront Sensor
Lauren H. Schatz, Jared R. Males, Laird M. Close +11
Adaptive optics systems correct atmospheric turbulence in real time. Most adaptive optics systems used routinely correct in the near infrared, at wavelengths greater than 1 micron.…
MagAO-X: project status and first laboratory results
Jared R. Males, Laird M. Close, Kelsey Miller +32
MagAO-X is an entirely new "extreme" adaptive optics system for the Magellan Clay 6.5 m telescope, funded by the NSF MRI program starting in Sep 2016. The key science goal of MagAO…
Magellan Adaptive Optics Imaging of PDS 70: Measuring the Mass Accretion Rate of a Young Giant Planet within a Gapped Disk
Kevin Wagner, Katherine B. Follette, Laird M. Close +11
PDS 70b is a recently discovered and directly imaged exoplanet within the wide (40 au) cavity around PDS 70 (Keppler et al. 2018, Müller et al. 2018). Ongoing accretion on…
