New method to achieve the proper polarization state for a vector vortex coronagraph
Jorge Llop-Sayson, Cole Kappel, Nemanja Jovanovic +1
The vector vortex coronagraph (VVC) performance in the laboratory and in ground-based observatories has earned it a spot on the NASA mission concepts HabEx and LUVOIR. The VVC indu…
Wavefront sensing and control in space-based coronagraph instruments using Zernike's phase-contrast method
Garreth Ruane, J. Kent Wallace, John Steeves +14
Future space telescopes with coronagraph instruments will use a wavefront sensor (WFS) to measure and correct for phase errors and stabilize the stellar intensity in high-contrast…
High-contrast Demonstration of an Apodized Vortex Coronagraph
Jorge Llop-Sayson, Garreth Ruane, Dimitri Mawet +7
High contrast imaging is the primary path to the direct detection and characterization of Earth-like planets around solar-type stars; a cleverly designed internal coronagraph suppr…
Enabling the next generation of scientific discoveries by embracing photonic technologies
Nemanja Jovanovic, Charles Beichman, Cullen Blake +46
The fields of Astronomy and Astrophysics are technology limited, where the advent and application of new technologies to astronomy usher in a flood of discoveries altering our unde…
Space Telescope and Optical Reverberation Mapping Project. VIII. Time Variability of Emission and Absorption in NGC 5548 Based on Modeling the Ultraviolet Spectrum
G. A. Kriss, G. De Rosa, J. Ely +164
We model the ultraviolet spectra of the Seyfert 1 galaxy NGC~5548 obtained with the Hubble Space Telescope during the 6-month reverberation-mapping campaign in 2014. Our model of t…
Simulations of a High-Contrast Single-Mode Fiber Coronagraphic Multi-Object Spectrograph for Future Space Telescopes
Carl T. Coker, Stuart B. Shaklan, A J E. Riggs +1
Directly imaging and characterizing Earth-like exoplanets is a tremendously difficult instrumental challenge. Present coronagraphic systems have yet to achieve the required $10^{-1…
