Low-order wavefront control using a Zernike sensor through Lyot coronagraphs for exoplanet imaging
R. Pourcelot, M. N'Diaye, E. H. Por +19
Combining large segmented space telescopes, coronagraphy and wavefront control methods is a promising solution to produce a dark hole (DH) region in the coronagraphic image of an o…
Experimental validation of active control of low-order aberrations with a Zernike sensor through a Lyot coronagraph
Raphaël Pourcelot, Mamadou N'Diaye, Emiel H. Por +11
Future large segmented space telescopes and their coronagraphic instruments are expected to provide the resolution and sensitivity to observe Earth-like planets with a 10^10 contra…
Estimating low-order aberrations through a Lyot coronagraph with a Zernike wavefront sensor for exoplanet imaging
Raphaël Pourcelot, Mamadou N'Diaye, Greg Brady +13
Imaging exo-Earths is an exciting but challenging task because of the 10^-10 contrast ratio between these planets and their host star at separations narrower than 100 mas. Large se…
Near-Infrared Stellar Populations in the metal-poor, Dwarf irregular Galaxies Sextans A and Leo A
Olivia C. Jones, Matthew T. Maclay, Martha L. Boyer +3
We present JHK observations of the metal-poor ([Fe/H] -1.40) Dwarf-irregular galaxies, Leo A and Sextans A obtained with the WIYN High-Resolution Infrared Camera at Kitt…
