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…
Empirical Modeling of Zodiacal Backgrounds to Improve JWST NIRISS/SOSS Data Reduction
Tyler Baines, Aarynn Carter, Néstor Espinoza +3
Zodiacal light -- arising from both the thermal emission and scattered sunlight by interplanetary dust -- is the dominant component of the sky background in NIRISS Single Object Sl…
Technique-agnostic exoplanet demography for the Roman era -- I. Testing a demography retrieval framework using simulated Kepler-like transit datasets
Akshay Priyadarshi, Eamonn Kerins, Michael D. Albrow +41
The Nancy Grace Roman Space Telescope (Roman) will unveil for the first time the full architecture of planetary systems across Galactic distances through the discovery of up to 200…
Highlights from Exoplanet Observations by the James Webb Space Telescope
Néstor Espinoza, Marshall D. Perrin
The James Webb Space Telescope (JWST) has started a revolution in exoplanetary science. From studying in exquisite detail the chemical inventories and physical processes in gas gia…
Effects of Jump Detection and Ramp Fitting Algorithms on NIRISS/SOSS Exoplanet Time-Series Observations
Aarynn Carter, Néstor Espinoza, Loïc Albert +4
Jump detection and ramp fitting are fundamental steps when elevating JWST data products from up-the-ramp measurements to integration level count rate images. Occurring at an early…
Spelunker: A quick-look Python pipeline for JWST NIRISS FGS Guide Star Data
Derod Deal, Néstor Espinoza
The James Webb Space Telescope produces some of the highest sensitivity imaging of the cosmos across all instruments. One of them, the NIRISS Fine Guidance Sensor, provides guide s…
Characterization of the visit-to-visit Stability of the GR700XD Wavelength Calibration for NIRISS/SOSS Observations
Tyler Baines, Néstor Espinoza, Joseph Filippazzo +1
When utilizing the NIRISS/SOSS mode on JWST, the pupil wheel (tasked with orienting the GR700XD grism into the optical path) does not consistently settle into its commanded positio…
Characterization of the visit-to-visit Stability of the GR700XD Spectral Traces for NIRISS/SOSS Observations
Tyler Baines, Néstor Espinoza, Joseph Filippazzo +1
In this report, we present the results of our analysis of trace position changes during NIRISS/SOSS observations. We examine the visit-to-visit impact of the GR700XD pupil wheel (P…
