The Multi-Core Integral-Field Unit (MCIFU) is a new diffraction-limited near-infrared integral-
field unit for exoplanet atmosphere characterization with extreme adaptive optics (xAO) …

Principles of Adaptive Optics describes the foundations, principles, and applications of
adaptive optics (AO) and its enabling technologies. This leading textbook addresses the …

Context. Direct imaging of Earth-like planets is one of the main science cases for the next
generation of extremely large telescopes. This is very challenging due to the star-planet …

The study of cold or obscured, red astrophysical sources can significantly benefit from
adaptive optics (AO) systems employing infrared (IR) wavefront sensors. One particular area …

As we look to the next generation of adaptive optics systems, now is the time to develop and
explore the technologies that will allow us to image rocky Earth-like planets; wavefront …

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 …

We present the conceptual design of GMagAO-X, an extreme adaptive optics system for the
25 m Giant Magellan Telescope (GMT). We are develo** GMagAO-X to be available at or …

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 …

Second-generation exoplanet imagers using extreme adaptive optics (ExAO) and
coronagraphy have demonstrated their great potential for studying close circumstellar …

The pyramid wave front sensor (PyWFS) has become increasingly popular to use in
adaptive optics (AO) systems due to its high sensitivity. The main drawback of the PyWFS is …
