Habitable World Discovery and Characterization: Coronagraph Concept of Operations and Data Post-Processing
Michael W. McElwain, Dimitri Mawet, Jean-Baptiste Ruffio +11
The discovery and characterization of habitable worlds was the top scientific recommendation of the Astro2020 decadal survey and is a key objective of the Habitable Worlds Observat…
High-contrast imager for complex aperture telescopes (HiCAT): 11. System-level demonstration of the Apodized Pupil Lyot Coronagraph with a segmented aperture in air
Rémi Soummer, Raphaël Pourcelot, Emiel H. Por +16
We present the final results of the Apodized Pupil Lyot Coronagraph (APLC) on the High-contrast imager for Complex Aperture Telescopes (HiCAT) testbed, under NASA's Strategic Astro…
Dimpled scalar vortex coronagraph laboratory demonstration
Niyati Desai, Garreth Ruane, Susan Redmond +3
Achieving the Habitable Worlds Observatory (HWO) goal of 10^-10 contrast at a separation of 3 /D across a 20% bandwidth requires coronagraph focal plane masks with both broadba…
Laboratory demonstration of low order wavefront control using light reflected off the vortex coronagraph
Clarissa R. Do Ã, Kane Sjoberg, Luke Lamitina +4
The paper reports the first laboratory demonstration of a low‑order wavefront sensing and tip‑tilt control loop using light reflected from a vector vortex coronagraph, achieving su…
High-contrast imager for complex aperture telescopes (HiCAT): 8. Dark zone demonstration with simultaneous closed-loop low-order wavefront sensing and control
Rémi Soummer, Emiel H. Por, Raphaël Pourcelot +27
We present recent laboratory results demonstrating high-contrast coronagraphy for the future space-based large IR/Optical/Ultraviolet telescope recommended by the Decadal Survey. T…
Overview, design, and flight results from SuperBIT: a high-resolution, wide-field, visible-to-near-UV balloon-borne astronomical telescope
L. Javier Romualdez, Steven J. Benton, Anthony M. Brown +17
Balloon-borne astronomy is a unique tool that allows for a level of image stability and significantly reduced atmospheric interference without the often prohibitive cost and long d…
