Breaking the brightness barrier: JWST/NIRCam DHS spectroscopy for high-precision time-series observations
Achrene Dyrek, John Stansberry, Louis E. Bergeron +12
Many of the most scientifically compelling exoplanets orbit bright nearby stars that exceed the brightness limits of existing JWST spectroscopic observing modes. To address this li…
slicersim: A python package to simulate image slicer spectroscopic observations -- application to the Lazuli Spectrograph
M. Rigault, Y. Copin, G. Aldering +8
Integral Field Spectroscopy (IFS) is a key technique to study galaxies, stellar and planetary systems, and transients, by spatially splitting the scene and dispersing this light on…
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…
NIRCam Performance on JWST In Flight
Marcia J. Rieke, Douglas M. Kelly, Karl Misselt +7
The Near Infrared Camera for the James Webb Space Telescope is delivering the imagery that astronomers have hoped for ever since JWST was proposed back in the 1990s. In the Commiss…
JWST NIRCam Defocused Imaging: Photometric Stability Performance and How it Can Sense Mirror Tilts
Everett Schlawin, Thomas Beatty, Brian Brooks +25
We use JWST NIRCam short wavelength photometry to capture a transit lightcurve of the exoplanet HAT-P-14 b to assess performance as part of instrument commissioning. The short wave…
JWST/NIRCam Coronagraphy: Commissioning and First On-Sky Results
Julien H. Girard, Jarron Leisenring, Jens Kammerer +53
In a cold and stable space environment, the James Webb Space Telescope (JWST or "Webb") reaches unprecedented sensitivities at wavelengths beyond 2 microns, serving most fields of…
