Visible-Light High-Contrast Polarimetry with MagAO-X: Characterization and Initial Results

MagAO-X is a visible-light extreme adaptive optics instrument on the 6.5 meter Magellan Clay Telescope, recently upgraded to enable high-contrast polarimetric differential imaging (PDI) in r', i', and z'filters. Polarimetry is a powerful technique for suppressing unpolarized starlight and isolating the faint, polarized...

Closed-loop atmospheric dispersion correction for high-contrast imaging with MagAO-X

Incoming starlight is refracted as it enters Earth’s atmosphere from the vacuum of space. The wavelength dependence of atmospheric refraction causes elongation of the broadband PSF of ground-based telescopes, especially in the visible spectrum. The result is degraded image quality alongside reduced coronagraph light-bl...

What the speck is that? Improving exoplanet imaging sensitivity by combining machine learning and physical models

Extreme adaptive optics observations of exoplanetary systems are limited at the smallest separations by speckle noise introduced by diffractive effects in the telescope and instrument system. To probe for lower-mass planets on close orbits, we need to improve starlight suppression with both optics and post-processing t...

No need to modulate: on-sky results of a neural network enhanced pyramid wavefront sensor and prospects for the ELTs

One of the main limitations of ground-based extreme adaptive optics systems (XAO) is the balance between the temporal and photon noise error. The unmodulated Pyramid Wavefront Sensor (uPWFS) promises significant gains in sensitivity over its modulated counterpart, but its practical use is limited by its linearity range...

Updating the SCExAO/CHARIS polarimetric calibration following the Nasmyth beam-switcher upgrade

Subaru/SCExAO/CHARIS enables near-infrared integral field spectropolarimetry. Quantitative polarimetry is useful for a variety of science cases, particularly measurements related to dust grain properties in circumstellar disks. This capability requires correcting for polarization effects from the optical path via a Mue...
