Challenge of direct imaging of exoplanets within structures: disentangling real signal from point source from background light
Jialin Li, Laird M. Close, Jared R. Males +19
The high contrast and spatial resolution requirements for directly imaging exoplanets requires effective coordination of wavefront control, coronagraphy, observation techniques, an…
On-sky, real-time optical gain calibration on MagAO-X using incoherent speckles
Eden A. McEwen, Jared R. Males, Olivier Guyon +15
The next generation of extreme adaptive optics (AO) must be calibrated exceptionally well to achieve the desired contrast for ground-based direct imaging exoplanet targets. Current…
MagAO-X Phase II Upgrades: Implementation and First On-Sky Results of a New Post-AO 1000 Actuator Deformable Mirror
Jay K. Kueny, Kyle Van Gorkom, Maggie Kautz +13
MagAO-X is the extreme coronagraphic adaptive optics (AO) instrument for the 6.5-meter Magellan Clay telescope and is currently undergoing a comprehensive batch of upgrades. One in…
High-Contrast Imaging at First-Light of the GMT: The Preliminary Design of GMagAO-X
Jared R. Males, Laird M. Close, Sebastiaan Y. Haffert +15
We present the preliminary design of GMagAO-X, the first-light high-contrast imager planned for the Giant Magellan Telescope. GMagAO-X will realize the revolutionary increase in sp…
More data than you want, less data than you need: machine learning approaches to starlight subtraction with MagAO-X
Joseph D. Long, Jared R. Males, Laird M. Close +17
High-contrast imaging data analysis depends on removing residual starlight from the host star to reveal planets and disks. Most observers do this with principal components analysis…
MagAO-X: Commissioning Results and Status of Ongoing Upgrades
Jared R. Males, Laird M. Close, Sebastiaan Y. Haffert +20
MagAO-X is the coronagraphic extreme adaptive optics system for the 6.5 m Magellan Clay Telescope. We report the results of commissioning the first phase of MagAO-X. Components now…
The Active Asteroids Citizen Science Program: Overview and First Results
Colin Orion Chandler, Chadwick A. Trujillo, William J. Oldroyd +20
We present the Citizen Science program Active Asteroids and describe discoveries stemming from our ongoing project. Our NASA Partner program is hosted on the Zooniverse online plat…
Making the unmodulated Pyramid wavefront sensor smart. Closed-loop demonstration of neural network wavefront reconstruction with MagAO-X
Rico Landman, Sebastiaan Haffert, Jared Males +12
Almost all current and future high-contrast imaging instruments will use a Pyramid wavefront sensor (PWFS) as a primary or secondary wavefront sensor. The main issue with the PWFS…
