The Lazuli Space Observatory: Architecture & Capabilities
Arpita Roy, Stuart Feldman, Pete Klupar +51
The Lazuli Space Observatory is a 3-meter aperture astronomical facility designed for rapid-response observations and precision astrophysics across visible to near-infrared wavelen…
Progress toward a demonstration of high contrast imaging at ultraviolet wavelengths
Kyle Van Gorkom, Ramya M. Anche, Christopher B. Mendillo +9
NASA's Habitable Worlds Observatory (HWO) aims to achieve starlight suppression to the level for the detection and spectral characterization of Earth-like exoplanets. Br…
The Space Coronagraph Optical Bench (SCoOB): 8. end-to-end numerical modeling of the testbed to estimate the contrast limits
Ramya M Anche, Kyle Van Gorkom, Kian Milani +9
The space coronagraph optical bench (SCoOB) at the University of Arizona is a high-contrast imaging testbed designed to operate in a vacuum to obtain a contrast better than 1e-8 in…
Approaches to lowering the cost of large space telescopes
Ewan S Douglas, Greg Aldering, Greg W. Allan +26
New development approaches, including launch vehicles and advances in sensors, computing, and software, have lowered the cost of entry into space, and have enabled a revolution in…
Microfabricated pinholes for high contrast imaging testbeds
Emory L. Jenkins, Kyle Van Gorkom, Kevin Derby +2
In order to reach contrast ratios of and beyond, coronagraph testbeds need source optics that reliably emulate nearly-point-like starlight, with microfabricated pinholes…
Simulating the efficacy of the implicit-electric-field-conjugation algorithm for the Roman Coronagraph with noise
Kian Milani, Ewan Douglas, Sebastiaan Haffert +1
The Roman Coronagraph is expected to perform its high-order wavefront sensing and control (HOWFSC) with a ground-in-the-loop scheme due to the computational complexity of the Elect…
Estimation of polarization aberrations and their effect on the coronagraphic performance for future space telescopes
Ramya M Anche, Sebastiaan Y. Haffert, Jaren N Ashcraft +5
A major goal of proposed future space observatories, such as the Habitable World Observatory, is to directly image and characterize Earth-like planets around Sun-like stars to sear…
Laboratory demonstration of the triple-grating vector vortex coronagraph
David S. Doelman, Mireille Ouellet, Axel Potier +5
The future Habitable Worlds Observatory aims to characterize the atmospheres of rocky exoplanets around solar-type stars. The vector vortex coronagraph (VVC) is a main candidate to…
Polarization aberrations in next-generation giant segmented mirror telescopes (GSMTs) I. Effect on the coronagraphic performance
Ramya M. Anche, Jaren N. Ashcraft, Sebastiaan Y. Haffert +8
Next-generation large segmented mirror telescopes are expected to perform direct imaging and characterization of Earth-like rocky planets, which requires contrast limits of $10^{-7…
Three-sided pyramid wavefront sensor. II. Preliminary demonstration on the new CACTI testbed
Lauren Schatz, Johanan Codona, Joseph D. Long +17
The next generation of giant ground and space telescopes will have the light-collecting power to detect and characterize potentially habitable terrestrial exoplanets using high-con…
The vector-apodizing phase plate coronagraph: design, current performance, and future development
D. S. Doelman, F. Snik, E. H. Por +50
Over the last decade, the vector-apodizing phase plate (vAPP) coronagraph has been developed from concept to on-sky application in many high-contrast imaging systems on 8-m class t…
Data-driven subspace predictive control of adaptive optics for high-contrast imaging
Sebastiaan Y. Haffert, Jared R. Males, Laird M. Close +11
The search for exoplanets is pushing adaptive optics systems on ground-based telescopes to their limits. One of the major limitations at small angular separations, exactly where ex…
