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 broadban…
Model validation and tolerancing of scalar vortex masks in the High Contrast Imaging Testbed (HCIT) facility
Niyati Desai, Garreth Ruane, Daniel Shanks +3
The Habitable Worlds Observatory (HWO) mission will require coronagraphs capable of suppressing starlight at the contrast level to directly image exo-Earths. High c…
A socio-demographic study of the exoplanet direct imaging community II
Lucie Leboulleux, Niyati Desai, Daniel Echeverri +9
Recognizing and addressing under-representation, exclusion, and problematic behavior within astronomy and astrophysics is crucial. In 2019, a survey was conducted at the Spirit of…
Implicit Electric Field Conjugation Through a Single-mode Fiber
Joshua Liberman, Jorge Llop-Sayson, Arielle Bertrou-Cantou +4
Connecting a coronagraph instrument to a spectrograph via a single-mode optical fiber is a promising technique for characterizing the atmospheres of exoplanets with ground and spac…
Integrated photonic-based coronagraphic systems for future space telescopes
Niyati Desai, Lorenzo König, Emiel Por +38
The detection and characterization of Earth-like exoplanets around Sun-like stars is a primary science motivation for the Habitable Worlds Observatory. However, the current best te…
Benefits of adding radial phase dimples on scalar coronagraph phase masks
Niyati Desai, Dimitri Mawet, Eugene Serabyn +4
Current scalar coronagraph focal plane mask designs are performance-limited by chromaticity. We investigate the effects of adding central Roddier and dual zone phase dimples to sca…
Visible extreme adaptive optics on extremely large telescopes: Towards detecting oxygen in Proxima Centauri b and analogs
J. Fowler, Sebastiaan Y. Haffert, Maaike A. M. van Kooten +38
Looking to the future of exo-Earth imaging from the ground, core technology developments are required in visible extreme adaptive optics (ExAO) to enable the observation of atmosph…
