The Near Infrared Imager and Slitless Spectrograph for the James Webb Space Telescope -- I. Instrument Overview and in-Flight Performance
Rene Doyon, C. J Willott, John B. Hutchings +60
The Near-Infrared Imager and Slitless Spectrograph (NIRISS) is the science module of the Canadian-built Fine Guidance Sensor (FGS) onboard the James Webb Space Telescope (JWST). NI…
Improving the speckle noise attenuation of simultaneous spectral differential imaging with a focal plane holographic diffuser
David Lafrenière, René Doyon, Daniel Nadeau Ãtienne Artigau +2
Direct exoplanet detection is limited by speckle noise in the point spread function (PSF) of the central star. This noise can be reduced by subtracting PSF images obtained simultan…

Loic Albert, David Lafreniere, Rene Doyon +37
The Near Infrared Imager and Slitless Spectrograph instrument (NIRISS) is the Canadian Space Agency (CSA) contribution to the suite of four science instruments of JWST. As one of t…
Gemini Planet Imager Observational Calibrations I: Overview of the GPI Data Reduction Pipeline
Marshall D. Perrin, Jérôme Maire, Patrick Ingraham +35
The Gemini Planet Imager (GPI) has as its science instrument an infrared integral field spectrograph/polarimeter (IFS). Integral field spectrographs are scientificially powerful bu…
On-sky observations with an achromatic hybrid phase knife coronagraph in the visible
Lyu Abe, Mathilde Beaulieu, Farrokh Vakili +4
CONTEXT: The four-quadrant phase mask stellar coronagraph, introduced by D. Rouan et al., is capable of achieving very high dynamical range imaging and was studied in the context o…
