Forward modelling coronagraphic images with a fully physical, differentiable digital twin of MagAO-X: first laboratory results
Matthijs Mars, Sebastiaan Y. Haffert, Louis Desdoigts +10
Post-processing of high contrast imaging data relies on an accurate model of the stellar point spread function (PSF). Current techniques build this model from the science images th…
NEXT: The Netherlands EXoplanet Testbed I. Goals and opto-mechanical design
Rico Landman, Sebastiaan Haffert, Louis Desdoigts +7
We report on the goals, design, and ongoing development of the Netherlands EXoplanet Testbed (NEXT), a high-contrast imaging testbed under construction in Leiden. NEXT is designed…
The final design of GMagAO-X: the wavefront sensing and control (WFS&C) architecture of GMagAO-X
Sebastiaan Y. Haffert, Jared R. Males, Laird M. Close +10
The Giant Magellan Adaptive Optics eXtreme (GMagAO-X) instrument has now been selected as an official part of the Giant Magellan Telescope's (GMT) instrument suite. The instrument…
The Roman Coronagraph Community Participation Program: pre-launch reference star list and impact of reference star properties on post-processing performance
Justin Hom, Schuyler G. Wolff, Jessica Gersh-Range +51
The upcoming Roman Coronagraph will be the first high-contrast instrument in space capable of high-order wavefront sensing and control technologies, a critical technology demonstra…
Optimal mode-sorting coronagraphy: limits of single-moded measurements for the Habitable Worlds Observatory
Yinzi Xin, Sebastiaan Haffert, Rico Landman
Conventional coronagraph architectures struggle to reach the theoretical limit of exoplanet detection at close working angles. Spatial mode-sorting is capable of reaching the theor…
WIde Separation Planets In Time (WISPIT): A Gap-clearing Planet in a Multi-ringed Disk around the Young Solar-type Star WISPIT 2
Richelle F. van Capelleveen, Christian Ginski, Matthew A. Kenworthy +17
In the past decades several thousand exoplanet systems have been discovered around evolved, main-sequence stars, revealing a wide diversity in their architectures. To understand ho…
