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…
The Holographic Dispersed Fringe Sensors (HDFS): phasing the Giant Magellan Telescope
Sebastiaan Y. Haffert, Laird M. Close, Alexander D. Hedglen +14
The next generation of Giant Segmented Mirror Telescopes (GSMT) will have large gaps between the segments either caused by the shadow of the mechanical structure of the secondary m…
Towards on-sky adaptive optics control using reinforcement learning
J. Nousiainen, C. Rajani, M. Kasper +15
The direct imaging of potentially habitable Exoplanets is one prime science case for the next generation of high contrast imaging instruments on ground-based extremely large telesc…
