Experimental Trials With The Optical Differentiation Wavefront Sensor For Extended Objects

Meghan Farris O'Brien, Sebastiaan Y. Haffert, Joseph D. Long +4

Commonly used wavefront sensors, the Shack Hartmann wavefront sensor and the pyramid wavefront sensor, for example, have large dynamic range or high sensitivity, trading one regime…

XPipeline: Starlight subtraction at scale for MagAO-X

Joseph D. Long, Jared R. Males, Sebastiaan Y. Haffert +15

MagAO-X is an extreme adaptive optics (ExAO) instrument for the Magellan Clay 6.5-meter telescope at Las Campanas Observatory in Chile. Its high spatial and temporal resolution can…

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…

MagAO-X: current status and plans for Phase II

Jared R. Males, Laird M. Close, Sebastiaan Haffert +15

We present a status update for MagAO-X, a 2000 actuator, 3.6 kHz adaptive optics and coronagraph system for the Magellan Clay 6.5 m telescope. MagAO-X is optimized for high contras…

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…

The Giant Magellan Telescope high contrast adaptive optics phasing testbed (p-HCAT): lab tests of segment/petal phasing with a pyramid wavefront sensor and a holographic dispersed fringe sensor (HDFS) in turbulence

Alexander D. Hedglen, Laird M. Close, Sebastiaan Y. Haffert +14

The Giant Magellan Telescope (GMT) design consists of seven circular 8.4-m diameter mirror segments that are separated by large > 30 cm gaps, creating the possibility of fluctuatio…
